The following is the result of research about diet considerations for dogs with calcium oxalate stones.
Water intake is the most important factor in preventing kidney stones. The Journal of the American Medical Associateion (June 19, 1991) says, "Adequate water intake is sufficient to prevent recurrence in over 60% of all cases." A study in the same journal in 1993 said a high fluid intake was associated with a 29% lower risk of stone formation. Drinking more fluids dilute the chemical salts in the urine and prevent stone formation.
Fresh water is a necessity and water from a clean bowl should be available allowing the dog to drink freely and as much as it desires. Switch from dry to canned food and add water to the food. Give dry food as treats. If you feed a homemade recipe, get as much water into it as you can.
I have increased the water in her recipe to make just short of a wet mush. Dr Adams suggested keeping as much water in the food as possible since Amie's not much of a drinker (never has been). How can we increase Amie's water intake?
When Amie's last tests in the Spring of 1998 showed blood in her urine, her vet, Claudia Lewis, said Amie needs fluids badly. She suggested giving Amie the turkey broth. She will prefer it to water if she's going to drink. Amie still drinks rarely in a day but at least she's taking in a little more fluid. She especially likes her broth slightly warmed to room temperature. We call it "drink treat" and make a fuss about how great it is. If she doesn't drink right away, we put it in the refrigerator to avoid bacteria formation.
My veterinarian, Claudia Lewis, gave me a computer print-out about nutritional and kidney disease. It said that the management of protein intake is the most important aspect of nutritional therapy for kidney disease. The protein must be highly digestible - (What is that?).
In human populations where protein is reduced or absent the risk of kidney stones is much reduced. A human study in Great Britain showed that vegetarians formed stones at 1/8 the rate of the general population.
A high protein diet can cause stones by increasing calcium in the urine. It lowers urinary pH and can increase uric acid. High quantities of animal protein can contribute to stone formation by increasing urinary calcium and oxalic acid excreting and by decreasing urinary citric acid excretion. Michigan State University Vet Clinic said to avoid red meats.
Eating animal fat has been associated with stone formation.
Fats should be unsaturated and constitute 3-8% of the diet.
Digesting carbohydrates are no problem for dogs with kidney disease.
A study showed that a high fiber diet decreased urinary calcium and oxalate levels.
Another study showed that defatted rice bran binds calcium in the intestine and decreases urinary calcium output. Amie is allegic to rice.
Some foods are oxalate-producing. These are very high oxalate-producing (this isn't the full list):Vegetables ~ beets, eggplant, leeks, sweet potatoes, okra, pepperSee the Low Oxalate Diet Book for a more complete list of oxalates and their relative oxalate production.
Greens ~ green beans or peppers, beets, celery, collards, eggplant, parsley, spinach, Swiss chard, chives, endive, kale, leeks, okra, rutagbega, summer squash, sweet potatoes, tomatoes
Legumes ~ beans, soy products including tofu
Grains ~ wheat germ
Nuts ~ all
Seeds ~ sesame and tahini
Fruit ~ berries, currants, concord grapes, figs, rhubarb, lemon, lime, plums, tangerines.
Chocolate is also oxalate-producing and toxic to dogs. Asparagus is said to break up oxalate crystals.
Calcium stones have an alkaline chemistry, so an acid ash diet may be less conducive to forming stones. An acid ash diet would increase the amount of meat, grains, eggs, cheese. It would limit the amount of vegetables, milk, fruit. This conflicts with the next paragraph.
Acidifying diets can contribute to stone-formation. Acid producing foods are: animal fats, potatoes, lemon, garlic, soy, beans, eggs, prunes, plums, cranberries, rhubarb, wheat, oats, peanuts, sugar. (Sucrose is the 7th listed ingredient in Hill's u/d diet!).
We were disappointed to discover that peanut butter is acid-forming and therefore not good for dogs with calcium oxalate kidney stones. It is by far Amie's favorite food. She will eat anything with peanut butter on it. She will rouse herself from a deep sleep when she hears the tub of no-salt-added, freshly ground peanut butter being opened. Claudia said even a trace of peanut butter isn't a trace to a 7 pound sensitive dog.
Amie's lithotripsy veterinarian, Dr Adams, recommended that we add a tiny amount of plain salt (salt with sodium silico-aluminate, no other additives) to each serving. Do not use kelp. Someone suggested sea salt. Salty food may cause side effects with Urocit.
The UC Davis nutritionist suggested Mortons salt substitute with potassium chloride rather than sodium choride. This is opposite of Adam's recommendation. I'll go with Adams on this one.
How much salt? When Amie's original recipe was analyzed, she was getting too little. Excess sodium may increase urine calcium exretion. Currently I lightly salt each portion, but how do I know if it is too much?
I thought that if I found a homemade diet that fixed her allergies, I could add food to balance her diet and add whatever was necessary to control her urinary problem. The balancing with real food has so far been impossible. How do I know what other nutrients she needs? Hill's and other canine nutritionists urged me to get canine nutritional supplements.
I had tried pet vitamins at various times, sometimes getting them from catalog companies specializing in natural food. Amie likes them, but she's allergic to the ingredients. A Hill's researcher recommended that I include a nutritional supplement with no additives and which is the least offensive. Name one.
Claudia doesn't carry supplements so she told me to go to another vet and read the labels. This vet said no dog needs supplementation if it is eating commercial food - a waste of money. Dog food is sufficient. I explained that that is precisely my problem. He very reluctantly let me look at the labels for two different supplement combinations and would not recommend either.
The difference in quantities and ingredients were vast. Really. Two choices of multi-supplements weren't in the same proportions compared to each other or in the same proportions that I had seen recommended in a book. How could there be such a difference in the two? What to do? I know proportion is important. I subscribe to the theory that different breeds have different nutritional requirements, but I could not figure from the labels which supplement was appropriate for Amie. It was a moot issue, anyway, since they all had some ingredient I knew she was allergic to.
I had given her PetGuard years ago to handle her flea problems because it is high in brewer's yeast and B vitamins. She loves them like a treat and one day I found her sniffing the jar and straining to get closer. So I added PetGuard to her diet and there was no reaction. Is the "naturally occurring" 6 mg of vitamin C conflicting with her kidney problem? I'm concerned that she's not getting enough other vitamins, minerals and trace minerals. I prefer to give her real food.
B vitamins often must be supplied since they are water soluble and are rapidly excreted in the urine. B vitamins have not been shown to be harmful.
Vitamin B-6 increases the transamination of a precursor of oxalic acid to glycine. There have been some cat studies which suggest B-6 supplementation may reduce urinary oxalic acid.
Vitamin B-12 has been recommended by two authorities to supplement Amie's custom homemade diet. Dr Larry Adams said it won't affect calcium oxalate stones - won't hurt, may help. The smallest dose I have found is a teeny weeny tableet of 500 ug and Amie should have about 50 ug a day. Claudia suggested finding a tiny dose at a bird store. The bird store owner scolded me out the door when I asked about it so I'm still searching.
Vitamin C is a precursor of oxalate. About half of vitamin C eaten is converted to oxalic acid.
I have been giving Amie PetGuard Yeast Tablets for the additional vitamin B. A canine nutritionist recommended not giving this supplement because it includes 6 mg of vitamin C. A PetGuard representative said the vitamin C is naturally-occurring in the food used to make the tablet, rather than an additive. She didn't think this form or amount of vitamin C would be a problem, but I don't know. The Animal Advocate, William Cusick, believes that dogs produce their own vitamin C and supplementing is harmful. He says many pet food companies add it to their pet food as an inexpensive preservative (antioxidant).
Vitamin D promotes intestinal calcium absorption and urinary calcium excretion (bad).
Magnesium should not be restricted or supplemented. There have been studies showing that magnesium supplements reduce oxalate levels. Magnesium and calcium compete for oxalate, but magnesium is less likely than calcium to bind with oxalate in urine. This is too tricky for the amateur. Messing up the magnesium balance can be fatal. However good food sources of magnesium include leafy grean vegetables, nuts, soybeans, seeds, and whole grains. Some of these foods are oxalate producing and allergy producing so do your research.
In humans, about half the daily requirement is usually prescribed. Restricting calcium may cause osteoporosis and restricting calcium may harm because it could result in increased urinary oxalate excretion. A study in the New England Journal of Medicine (March 25, 1993) shows that calcium-rich food can actually prevent stones. The Harvard School of Public Health found that men who had lots of calcium in their diet showed a 33% lower risk of stone formation than men who ate little calcium.
It's interesting that canine nutritionists recommend calcium supplements but don't specify which kind or are in conflict with each other. Not all calcium supplements are alike. They react differently based on the animal's acid-base balance. That's why it is so important to know an average urine pH.
The UC Davis canine nutritionist we consulted recommended calcium carbonate, given Amie's calcium oxalate kidney stones. Calcium carbonate neutralizes stomach acid needed for calcium absorption. It is the least expensive form. But from what source? It can be made from ground limestone or ground oyster shell. Oyster shell is the poorest form. Limestone is marginally better, depending on how finely it is ground. Someone suggested Tums. I contacted the nutritionist, who said bonemeal is preferred. She said bonemeal is the most common supplement used to balanced calcium and phosphate, but may be allergy-producing.
I use Kal brand bonemeal powder, which is another form of calcium carbonate. The label says, "Edible bone from bovine sources with marrow and nothing more. The source of this product is processed under extremely sanitary conditions at low temperatures in order to preserve all major and trace nutrients present in natural edible bonemeal powder." I called Kal to ask some questions and was referred to its product specialist. He said that regardless of what was on the label, all of their calcium carbonate is "mined from the ground". Isn't bonemeal a form of calcium carbonate? He was so rude I really am reluctant to call again.
Make sure you don't get a calcium supplement with any other mineral, especially magnesium.
Call the Calcium Information Center for more info (800-321-2681).
Call New York Hospital-Cornell Medical Center and Oregon Health Sciences Univeristy toll-free hotline (800- 321-2681).
The New England Journal of Medicine study showed that men with the highest consumption of potassium (fruits and vegetables) had only half the risk of developing kidney stones. Vets strongly recommend not supplementing with potassium.
Digestive enzymes have been recommended by more than one source. The PetGuard rep said they will result in effective digestion and increase thirst. We got Dr Goodpet's canine digestive enzymes with lactobacillus acidophilus. So far we haven't seen increased thirst with Amie, but the frequency of her urinations have increased from 3 to a high of 11 per day, now settling in at around 5 or 6 per day - her pre-lithotripsy level. We noticed an increase in volume, which might concern us, except that the color is still yellow and therefore, not dilute.
Dr Larry Adams, who performed the lithotripsy, recommended not giving digestive enzymes or any naturopathic supplement. He didn't give a reason. Because I have seen a fairly detailed website correlating urine and saliva pH with stones and other treatments, I will continue the digestive enzymes until I get more info pro or con.
Eskimos live on a diet of fatty fish but rarely have kidney stones. A doctor in Scotland found fish oil as a preventative for kidney stones. In Glasgow researchers found that fish oil with evening primrose oil sharply reduced urine calcium levels. I gave Amie omega-3 fatty acids for a while, but didn't know what good it was doing. Fish liver oil may increase the chance of stone formation.

ADJUSTING AMIE'S DIET
"THE ANIMAL ADVOCATE"
WORK IN PROGRESS
AMIE'S CURRENT RECIPE
ADJUSTING AMIE'S DIET
When it was determined that Amie had kidney stones, it was recommended that she stop eating venison because red meat is more stone-producing than poultry. I was very nervous about trying poultry because there is quite a bit of agreement that chicken is allergy-producing. Figuring that if she could tolerate poultry, I would rather cook a gigantic turkey every few months and freeze it than cook chicken more frequently.
I tried the recipe with a drug-free frozen turkey breast. Shelton Farms produces free-range turkeys raised without antibiotics or artificial growth stimulants and are considered the highest quality turkey you can get. She did well on the turkey breast and I began cooking whole turkeys.
After it was determined that Amie was not going to react to the turkey - groats - vegetable diet it was recommended that we gradually test ingredients that are on the Hill's Prescription dog food labels. If Amie did OK, we could switch her to canned food which would handle the urinary condition. The problem is that the labels list additives, instead of real food. Of Hill's four commercial dog foods which help a urinary problem all had ingredients she can't tolerate - not to mention the preservatives and other stuff.
Since she was doing so well on this diet, we decided not to change anything until after the urinary problem had been solved. She has basically been on this diet (See Amie's Custom Recipe) now since October 1996. How can we get her diet balanced to handle both the allergies and the urinary problem?
Three canine nutritional specialists promised to analyze Amie's diet to make it more balanced. One even required us to have a sample of Amie's food analyzed by Woodson-Tenet Laboratories, a pet food testing laboratory, before he would comment on her diet. The Woodson Lab results showed that her original homemade diet was low in sodium, fat and calcium. We made some adjustments that did have a positive effect (confirmed by lab tests). The three who had promised did not follow through. They simply did not do it. After offering their assistance, they would not respond to Claudia's prodding and just blew us off. Why promise in the first place?
"THE ANIMAL ADVOCATE"
In preparing this information for Amie's web page I searched for allergies and stones in dogs as I had a year ago to see if anything new had popped up. I found William Cusick (he calls himself "The Animal Advocate") who was a researcher with the now extinct National Research Council. He was instrumental in recommending requirements for dog food. He will design a custom-made diet based on your pet's breed and medical history. I received a packet of information.
Bill's diet included wheat and corn, which Amie is allergic to. He recommended parsley and garlic, which we now know Amie shouldn't have. And he suggested broccoli, which, is not oxalate-forming.
I was grateful for Bill's thoughtfulness and completeness in tailoring a recipe for Amie but found that I can't make it. I don't live in a laboratory, I live in the real world. One of the ingredients he recommended, for example, was a large turkey gizzard per weekly batch of food. I live near one of the largest turkey producers in the world and I cannot get a large turkey gizzard every week.
Another problem I have with his recipe is that it makes a batch of food to last a week. From a food safety standpoint, I don't feel comfortable saving frozen-defrosted-cooked meat for a week in the refrigerator.
Bill's very detailed list of recommended nutritional supplements are simply not available in the small quantities or the proportions he recommends. He strongly advised me to stop giving Amie PetGuard Yeast Tablets (6 mg vitamin C) because dogs make their own vitamin C and vitamin C causes her type of stones. I called PetGuard and spoke with a wonderful representative who spent about 45 minutes with me and gave me some very useful information. She said the vitamin C in the yeast tablet is not added, but is naturally occurring such as the vitamin C in the broccoli Bill recommends. This is confusing. She offered to send more information but didn't.
Nevertheless, it was worth $25 to see what Bill would come up with. If you have a larger dog maybe his recommendations would seem more reasonable. I mention him at all because I believe he is on the right track. Most of the people who call themselves pet nutritionists don't know nearly as much as he does. He is the only source I found that believes different breeds have different nutritional requirements and his internet page is quite persuasive. I learned for example that poodles shouldn't have carrots. He also believes that artificial additives can be harmful. Given the dollars I have spent chasing other leads, my money was well spent on "The Animal Advocate's" customized recipe. I used his information to question other nutritionists and compare to other info I found. I wish, though, that he knew more about kidney stones and acknowledged the limitations of his knowledge.
A representative from Hill's told Claudia about a veterinarian at U. C. Davis that formulates special-need diets. One of the staff members suggested we first try the Hill's u/d diet (been there). Then she suggested trying an Elimination Diet (done that). November 21, 1997 we sent her the info she needs. I also included "The Animal Advocate" notes.
The canine nutritionist at UC Davis reviewed Amie's data. She believes Amie now has indications of struvite disease, which complicates a dietary prescription. Struvite stones are due to infection. She made the following recommendations.
1) Avoid oxalate-forming foods such as spinach, rhubarb and parsley.
2) Discontinue onions because they contribute to Heinz body formation in erythrocytes (anemia). Because garlic is of the onion family, I've cut it out, too.
3) Celery and carrots contribute little to the overall composition of the diet, but may be continue to be included. In order to include some green food I've started to use celery tops instead of the ribs. I continued to use organic carrots because I believe in their ability to detoxify the liver and provide additional nutrients, but based on The Animal Advocate's info about carotene, I've stopped adding that, too.
4) She suggested vitamin and mineral supplements which are not available in my area or on the Internet, but I'm tracking this down. One of her suggestions is 50 micrograms of vitamin B-12. The smallest amount I can get is 500 micrograms in a teeny weeny tablet. I figured I could grind up a batch of supplements 10 times a regular dose and use one B-12 tablet, making 10 doses at once, but I don't have the recommended supplement. The supplement issue continues to be very difficult.
WORK IN PROGRESS
Amie's diet is a work in progress. While it seems to be working better than any other food, we know it isn't fully balanced. She has been on a restricted diet since July 1996 and I'm concerned about the effect of a lack of other nutrients. I frequently add steamed vegetables but still feel it's lacking.
Her homemade recipe is working very well in that her her coat is thick and full. It tends to be on the dry side, without much luster. She is jet black and her hair is turning gray. She occasionally will chew her paws and tail, indicating some allergic reaction, which became worse over the winter and exploded in the spring of 1998.
Claudia recommended feeding smaller portions more often and to see how much water I can get into her food, adding water to her plate if necessary. She won't eat a sloppy mess of food, but I was able to increase the water in her recipe batch by more than 150%. She still won't drink water but she will drink defatted, homemade turkey broth.
A canine kidney specialist at UC Davis recommended substituting 1/8 teaspoon of baking soda for the Urocit, which was making her sick. She was getting this dose for two meals and a tiny bit more at her night meal. Dr Larry Adams said just changing the pH of her urine with baking soda doesn't get to the underlying issue. He recommended a liquid form of Urocit (Polycitra-K) which is a candy-like liquid. Amie really doesn't like it mixed in her food so we started squirting it in her mouth. This just didn't work for her. She felt sick, stopped eating and developed sores on her back.
The PetGuard rep also suggested I check for acid-base balance in my macrobiotic books. She also recommended CO-Q-10, but I don't know the right dose for a 7 pound dog. After some research I began adding a slight pinch of the powder to her food. Been doing this for about a year. So far she has lived about 18 months longer than predicted. Has the CO-Q-10 helped?
The Animal Advocate recommended broccoli in his recipe. Also, asparagus is said to break up oxalate crystals - will research. Alkaline-forming foods include chlorophyll foods and millet - will research.
AMIE'S RECIPE AS OF May 14, 1999
Note: This has been designed specifically for Amie Hinchman-Wilcox, a 7 pound toy poodle with food allergies and a tendency to form calcium oxalate kidney stones. It is included here to show the result of food testing and to include the recommendations of canine kidney specialists. Do not use for your pet without consulting with your veterinarian. We KNOW it is not yet balanced, but it is where we are right now. I don't think it is just a superstition that chicken (or turkey) soup is good for you.NEW DIET 10-26-00
This batch makes about six cups of food. (Turkey preparation instructions follow.)
6 cups Water (bottled spring)
1 cup Buckwheat groats (organic)
1 cup Turkey (cooked), finely minced and loosely packed (about 1/4 lb)
4 tablespoons Sunflower oil, cold pressed or a mix of Sunflower oil and turkey fat
1 1/2 teaspoon Bonemeal powder (calcium carbonate)
Turkey broth, homemade
Put all but the broth in a large pot and stir. Cook over medium heat until you smell the buckwheat. The mixture should be smooshy and most of the water absorbed.
Serve 3/4 cups slightly warmed food with
~ A slight amount of plain salt (salt, sodium silico-aluminate)
~ About one-half teaspoon digestive enzymes
~ Several tablespoons of broth. Mix well.
~ One drop of bird vitamins
~ One drop of echinacea (no alcohol)
~ One-half PetGuard vitamin
Amie eats 3 times a day.
~ I have also cooked a whole, organically grown chicken and a turkey breast. These take less time but I have to do it more often, so I prefer to cook a large turkey.
~ Joy of Cooking says ¼ lb of meat is equivalent to about ¾ cup packed, shredded meat. That is about 1 cup loosely filled cup. I haven't actually weighed a loosely filled cup of turkey.
~ Hill's u/d diet is 3.2% protein. The lab analysis of Amie's recipe showed 4.7% protein. I will reduce the proportion of protein a bit.
~ I had been making Amie's food with rendered turkey fat, skimmed from the freshly made broth, but it is acid-forming so I eliminated it. The UC Davis nutritionist said it wouldn't hurt to substitute the fat for the sunflower oil. It gives the food more flavor.
~ The original recipe included carrots. The "Animal Advocate" sent me info that said poodles don't do well eating carotene, and although he said it would be okay, I cut it out of the recipe to see if there was any effect.
~ I used to add 3 ribs of celery until I discovered that celery is oxalate-producing.
~ The original recipe included onions and garlic. The UC Davis nutritionist said onions cause Heinz body formation of erythrocytes (anemia), so I cut out onion and garlic. Then vet Claudia Lewis said garlic has such good effects to try it. Amie loves garlic. If she shows any tendency toward anemia on her next tests, I will eliminate it.
~ The Animal Advocate recommended including broccoli. Broccoli is not oxalate-forming. Amie loves broccoli.
PREPARING THE TURKEY
1 frozen Shelton turkey - the largest I can get
4 large cloves of garlic, coarsely chopped
About 3 gallons spring water
A 28 lb turkey yields at least 28 cups of finely minced turkey and about 28 cups of broth.
The Hard Way
Cut the turkey into parts and skin it. Discard the skin. Put the turkey parts into 2 large stock pots and cover with water. It takes about ½ hour to begin to simmer. After about an hour foam begins to form. Skim and discard. After the foam subsides, add the garlic. Simmer about 1 ½ - 2 hours total.
When cooked, remove the meat to a colander where the excess liquid and fat can drain into a collecting bowl. This liquid is put into a stock pot.
The Easy Way
Reserve the neck, gizzard, heart, etc. Roast the bird uncovered and unstuffed with some water in the pan. Cook 15 minutes per pound at 325 or until done. I baste it a few times and cover with foil when it is brown. Save the juices and the reserved parts for making broth.
Carefully remove the meat from bones and gristle. I prepare the meat as if it were for human consumption (omitting the icky, slimy parts). Put the bones into the broth and cook for about an hour.
Very finely mince the meat in an electric chopper/grinder and mix it all in a large bowl. It turns out that there is about 2/3 cups white meat to about 1/3 cup dark and about ½ teaspoon organ meats to make 1 lightly filled cup (or ¾ cup packed meat, which equals about ¼ lb). Each cup of meat is put in a freezer baggie and immediately frozen in a freezer ziplock bag. The broth is strained, pressing the vegetables to extract juice, then chilled.
The next day I skim the top of the broth to collect the turkey fat - discard it or save and freeze for use in the recipe, or save for your own use. Then I measure the broth (which is really a dense gelee) into 1 cup portions and freeze them in sandwich baggies in a ziplock freezer bag.
Irene emailed me recommending Pat McKay's raw food diet (www.patmckay.com/). Irene says her doberman with wobbly legs (like Amie's) saw quick results on this diet. It seems to fly in the face of every bit of research I've found so far with the meat to carb ratio very high. The raw part seems to make such sense. Amie has been eating the turkey-groats diet with some steamed non-oxalate producing vegetables since 1997 and I've never felt that it was the best diet. It was the best we could come up with.
I feel I have to keep experimenting. I found Shelton's organically raised ground turkey at the natural food store and got Pat McKay's supplements. Her calcium is needed because "raw meat is very high in phosphorus and must have a balance of calcium and magnesium to be absorbed and utilized by the body." It was much easier to make food this way. Amie didn't scarf down the food like she would some sashimi-grade tuna, for example, but she ate. By morning common sense told me to abandon the high protein diet. I continued her custom diet using raw meat and Pat McKay's supplements. By the next day I returned to Amie's usual cooked turkey custom diet. She wasn't too interested in food at this point.
Pat McKay answered my request for information. Here's what she said."You do not have to modify our diet for Amie's kidney stone condition. Unfortunately her problem is not unusual. We get requests for what to do about kidney stones on a daily basis. Keeping the system acidic is very important. That's why we recommend feeding only meat and vegetables. Grains are the main source of this problem. The studies done on protein where done on cooked protein. Raw is totally different. Dogs and cats have a much more difficult time digesting and assimilating cooked foods of any kind. By nature they were not meant to eat cooked foods. For the past 20 years, I have seen only improvement by going raw and continuing to keep the protein high at 75%. You must also use our Calicum+Plus. It is the only calcium presently on the market that does not leave calcium deposits which convert to stones. Calcium carbonate is a man-made calcium that leaves deposits. Also you must have a complete line of vitamins, minerals and trace minerals. The body has to have balance."I believe that Pat doesn't know that not all kidney stones are alike. Calcium oxalate stones are formed in an acidic system. I think this diet would be dangerous. I am interested in the raw aspect, though. Also, Amie's diet includes buckwheat groats. Buckwheat is a grass, not a grain. If I ever have another dog I surely will not feed it commercial food but I don't know what recipe I'd follow.
The best thing I can recommend to others with similar health problems in your dog, is to feed the appropriate prescription diet as recommended by your vet. If your dog is allergic to it, try the Elimination Diet first to determine what foods your pet is allergic to. Maybe you can find a commercial product that works. That would certainly be an easy solution. I would prefer to find a homemade recipe with fresh ingredients and no artificial additives. Easier said than done.Forward to: How to Work with Veterinarians
