Not surprised at all that many owners of dogs with cancer choose to go the raw and homecooked route.

You never want to get the news that your dog has cancer. However, it’s good to know there are many effective treatments available to dogs now. One of the simplest and most affordable is a good diet. While the food you give your dog won’t necessarily cure cancer, it can make a significant difference in your dog’s ability to fight the disease.

If your dog is diagnosed with cancer, you should make it a priority to help him maintain as healthy a body as possible with a sound immune system. This may require some adjustments to his diet, because many cancers cause dogs to lose weight and muscle mass. This condition, called “cachexia,” can be caused directly by the cancer or it can be the side effect of some cancer treatments.

In a series of studies, Dr. Ogilvie, a leading cancer nutritionist, looked at the effect of different diets on dogs with cancers, specifically lymphomas. He discovered that dogs with cancer actually metabolize some nutrients differently than healthy dogs.

For starters, dogs with cancer use carbohydrates differently. In his study, Dr. Ogilvie found that the cancer grows rapidly with plenty of glucose available. Specifically, the cancer cells gain energy by using simple sugars, such as glucose, which is a breakdown product of carbohydrates. Therefore, you can help deprive the cancer cells of fuel for growth by decreasing the amount of carbohydrates in your dog’s diet.

In contrast to their use of carbs, cancer cells don’t utilize fat very well. The omega-3 fatty acids in particular are useful for cancer patients. These fatty acids decrease the development of carcinogen-related tumors and decrease the growth of solid tumors. They also help alleviate some side effects of chemotherapy and radiation treatments and provide healthy cells with energy. Flaxseed oil and cold-water fish oils such as salmon oils are excellent sources of omega-3 fatty acids that you can consider adding to your dog’s diet. Omega-6 fatty acids such as safflower oil are not recommended, with the exception of cases of an unusual skin growth called mycosis fungoides.

So a diet with low carbohydrates and a fair amount of omega-3 fatty acids can help your dog. But what about protein? Tumor cells will use protein for energy before fat; that’s why cancer patients lose muscle and body condition. The cancer cells fight with the normal cells for the amino acids they need. An ideal diet for a dog with cancer, then, contains a moderate amount of top-quality protein.

You may also want to supplement some amino acids, such as arginine, which is known for helping to maintain the immune system. A strong immune system can help your dog’s body fight cancer. Glutamine is another important amino acid that helps to preserve the gastrointestinal tract and may decrease any vomiting or diarrhea seen as a side effect of some chemotherapy regimens. Finally, glycine specifically protects the kidneys from the side effects of the chemotherapy drug called cisplatin. You can really boost your dog’s ability to fight the cancer by making sure he gets enough of these three important amino acids.

Other supplements that might be beneficial include vitamins A, C, and E and selenium. These vitamins and the mineral selenium are known for their antioxidant properties; they all fight the free radicals related to aging. Vitamin A can even be supplied in the form of cod liver oil that will also provide extra omega-3 fatty acids. Vitamin E and selenium act as antioxidants but need to be given in the proper balance. Vitamin C is not only an antioxidant but also an acidifier. Studies have shown that an alkaline body aids cancer growth, so it is conceivable, though not proven, that an acidic body may slow down cancer growth. While all of these supplements are helpful, too much of any one of them can be dangerous, so be sure to consult with your veterinarian about the proper dosage before you add them to your dog’s diet.

A few additional dietary additions that may be helpful include garlic, which is known for counteracting many carcinogens, and both black and green tea. It may be tricky to get your dog to enjoy an afternoon cup of tea with you, though! Herbs such as echinacea, bromelain and milk thistle may also be appropriate additives for specific cancers.

While we can’t say that diet changes will cure most cancers, some dietary adjustments may help give your dog a longer survival time with a better quality of life. And luckily, most foods, unlike many cancer treatments, have very few side effects.

Dr. Deb M. Eldredge graduated from Cornell University as the first recipient of the Gentle Doctor Award. She has been in private practice and is active in virtually all dog sports. She is also an award-winning writer — her book “Cancer and Your Pet” was a finalist in the Dog Writers of America (DWAA) contest, and “Head of the Class,” a training book written with her daughter, won the Best Training and Behavior Book Award from DWAA in 2006.

The answer is no and no. At least for the commercial dog food I feed mine (Propet Large Breed Puppy Formula) there is no, none, nunca, nyet sugar listed in the ingredients. Now somewhere on this planet there is bound to be a dog food that has sucrose, fructose (e.g. corn syrup), or glucose listed as an ingredient, but it's doubtful if you will find many - even for the cheap brands. So from my perspective commercial dog food is not loaded with sugar.

The second no is for the leap of faith that feeding sugar to dogs is going to induce cancer or increase the incidence. Now it may play havoc with the blood sugar levels, and possibly lead to diabetes - as is the case for humans. Not to mention weight gain and skeletal problems.

As for the article you cite Dr Eldredge starts out on track per the Ogilvie research but quickly veers off path quickly. What Ogilvie found was that in combination with Chemotherapy (Doxorubicin), a lymphoma dog fed high doses of Arginine plus fish oil lived longer than those not fed those two supplements. The result of his research was to support the then new Hills c/d dog food formula which added Arginine and fish oil. With my lymphoma puppy I just gave her the Arginine and fish oil, avoiding Hills.

He also discussed the role of fish oil normalizing lactic acid levels, which he previously showed as being elevated in lymphoma dogs. Thus we arrive at the first veer off track:

Studies have shown that an alkaline body aids cancer growth, so it is conceivable, though not proven, that an acidic body may slow down cancer growth.

A lymphoma puppy as just stated has a high lactic acid blood content and subsequently a lower pH. The lactic acid is a by product of fermentation as the sugar is consumed by the cancer cells leaves the host animal to get its energy nutrition through non-carbohydrate sources. Yet a high lactic acid level is a poor prognostic factor for the dog's survival. Thus her statement of saying a low pH is desirable is off the wall.

Flaxseed oil and cold-water fish oils such as salmon oils are excellent sources of omega-3 fatty acids that you can consider adding to your dog’s diet. Omega-6 fatty acids such as safflower oil are not recommended

Another off the wall comment by Eldredge. Flaxseed oil is not a good source of Omega-3s relative to fish oils. In fact Flaxseed has just the precusors of both Omega-3s and Omega-6 fatty acids (e.g. Alpha-LNA, and Linoleic Fatty Acid in a ratio of 43% to 26%) that must be converted by the host animal into the long chain Omega FAs. Example: There is 230 mg of Alpha-LNA per 1 gm of Flax oil. The actual amount that gets converted in humans (via one radioactive isotope study) to 3-Omega fatty acids is somewhere between 4.6 mg – 34.5 mg 3-Omega fatty acids per 1 gm of Flax Oil. Let's not forget the Linoleic FA conversion to Omega-6 FAs that has been shown to promote cancer. Apply the 43% to 26% ratio and you arrive very little benefit in giving Flax oil. Compare to fish oil which has the Omega-3s 180 mg EPA + 120 mg DHA or 300 mg of 3-Omega fatty acids per 1000 mg of fish oil. No conversion by the host animal needed. Thus Eldredge is incorrect in saying Flax has no potential for conversion to the Omega-6s, and is incorrect in saying it's a rich source of Omega-3s.

The third off track for Eldredge is the recommendation of garlic. Research studies have been performed with garlic extracts, and concentrates of active components. In order to acheive the same levels with raw or processed garlic one would literally have to poison the dog (hemolytic anemia) to get the same effect.

I have no disagreements with Eldredge per the use of Vitamins in dogs undergoing Chemotherapy as a means to possible enhance the drugs, or help protect against the harmful effects (e.g. I gave my Lymphoma puppy Co-Enzyme Q to help protect the heart muscle mitochrondria against the harmful effects of Doxorubicin - with research literature to back it up). But you have to put Vitamins in the context as an adjunct treatment, where it probably won't do any harm, but may have a minimal effect at best. Still when you have a dog with cancer anything is worth a try.


As flipgirl asserts (and as I do) cancer in dogs is genetic, and it matters not whether you feed raw, cooked, commercial or otherwise. Irresponsible breeding is the principal cause IMO. Keep that in mind the next time you hear someone casually say they want to breed their dog. Do they know the cancer history of all siblings, parents and siblings for a few generations back? Do the so called professional breeders care about oncogenes in their breeding stock? Would they be willing to take their breeding stock out of breeding if the history indicated cancer in the line? Doubtful. The cancer epidemic speaks for itself.

As Catlady points out part of the epidemic is the realization it exists. In past years it would have been misdiagnosed at best. Add in that despite the rumored horrors of commercial dog food, our dogs none the less are living longer on it, also allowing the cancer to appear with age.
