Many veterinarians suggest that an appropriate cancer diet for dogs should generally be low in carbohydrate and high in fat and protein. This page explains why such a diet is appropriate.

Basic Components of a Dog Cancer Diet

From a holistic point of view, many forms of dog cancer are caused by a weakened immune system, which in turn is caused, amongst other things, by a poor diet. It is important, therefore, that a natural and nutritious diet, enriched by appropriate natural supplements and vitamins, be given to a dog with cancer.

The first thing that many veterinarians tell dog parents to do when their dogs have been diagnosed with cancer is that, they should not be feeding their dogs commercial kibble, which is cooked under high heat resulting in the production of various carcinogens (such as acrylamide). Instead, a natural, organic home-cooked or raw diet is recommended.

There are also suggestions that dogs with cancer be fed a special dog cancer diet, namely, a low-carbohydrate, high-fat, high-protein diet.

In an article entitled "Nutritional Approaches to Cancer Therapy", Dr. Ogilvie (DVM at Colorado State University) states that most cancer cells rely on simple carbohydrates (sugars) and to some extent, proteins, as energy sources to grow and reproduce. However, cancer cells do not do so well on specific types of fats. He feels that a proper diet can help in cancer treatment, and suggests that a dog cancer diet should contain:

  • Unsaturated Fats: Unsaturated fats, especially high quantity of Omega-3 fatty acids (e.g. flaxseed oil), should be given to dogs with cancer. Other studies have also indicated that Omega-3 fatty acids can make tumor cells more susceptible to chemotherapy and the dog patient's own immune system. What's more, there is evidence that Omega-3 FAs may help prevent the recurrence of cancer after remission. On the other hand, Dr. Ogilvie warns that Omega-6 fatty acids (e.g. borage oil, primrose oil) have been proven to accelerate cancer growth; therefore, Omega-6 should be limited or avoided.
  • Proteins and Amino Acids: A higher amount of proteins and amino acids should be included in a dog cancer diet. The proteins must be of high-quality (human-grade) and easily digestible. In addition, two amino acids that should be present the diet are arginine (an immune system booster) and glutamine (which supports and maintains the health of the GI tract).
  • Complex Carbohydrates: If you want to include carbohydrates in your dog's cancer diet, use only very small amounts of complex carbs such as oat, brown rice, barley, etc.
  • Simple Carbohydrates: Simple carbs (sugars) should be kept to a minimum. Note, however, that it doesn't mean you should not give veggies or fruits to your dog at all. Some veggies (e.g. broccoli, carrots, brussel sprouts) contain a lot of vitamins and minerals and are beneficial to dogs.

As a general guideline, a dog cancer diet that contains 50% to 60% of total calories from fat, 30% to 50% of calories from protein, and the remaining portion of calories from soluble carbohyrates is recommended for dogs with cancer.

An Example of a Dog Cancer Diet

Fats - Flaxseed Oil and Cottage Cheese

Ever heard of the "Budwig Protocol" or "Budwig Diet"? It is a simple diet of cottage cheese and flaxseed oil suggested by Dr. Johanna Budwig (a German research scientist). In her life-long research on fats and proteins and how they affect our health, Dr. Budwig found that when organic flaxseed oil are combined with organic cottage cheese, which is rich in sulfur protein, the chemical reaction produced makes the oil water-soluble, making it easy to be absorbed into the cell membrane. Thus, mixing cottage cheese with flaxseed oil supplies your body with an abundant supply of lipoproteins. Dr. Budwig claimed when cancer patients followed this diet for around 3 months, the size of their cancer tumors would gradually reduce.

There are also anecdotal stories about how dog parents have successfully treated their dogs with cancer by using this diet. Since flaxseed oil and cottage cheese are healthy foods, it seems there is no harm in trying. However, a word of caution: some dogs are prone to develop pancreatitis when fed excessive amount of fats, so watch your dog carefully if you do decide to try this diet. You may want to use some herbs (e.g. dandelion or burdock) to help his pancreas.

For the Budwig Diet, here is what you need to do:

Add one tablespoon of organic flaxseed oil to half a cup of organic cottage cheese. Using a mixer or blender, blend the two ingredients well. You can feed it to your dog three times a day for at least 3 months.

For old dogs, it is better to substitute cottage cheese with plain yogurt since old dogs may not be able to digest the lactose in cottage cheese.

This video shows you the key points to remember when preparing the Budwig Diet:

High-Quality Proteins and Complex Carbs

The rest of the cancer diet should avoid flaxseed oil and cottage cheese (or yogurt), since your dog will be getting sufficient amounts of such food items in the Budwig diet.

For the rest of the diet, you should include high-quality proteins and amino acids (e.g. organic chicken, sardines, turkey, pork, lamb, beef), as well as beneficial veggies and herbs (e.g. shiitake mushrooms, cauliflower, cabbage, red and yellow bell peppers, broccoli, carrots, brussel sprouts, garlic, parsley, ginger, fresh berries, etc.) You may also include some complex carbs like brown rice, barley, etc.

Feeding Tips

A dog with cancer will understandably lose his appetite, resulting in malnutrition. One simple way to stimulate his appetite is to warm his food up to around 100°F (about 38°C) to release the aromas in the food. Another way is to add a little bit of sea salt to the food.

Natural Supplements

Natural supplements should form an integral part of a dog cancer diet. Specifically, you should give your dog the following supplements if your dog has cancer:

Digestion Enzymes

Icon for Notice
Did you know that herbs can also help dogs with cancer? Visit this page to find out more!
Even an all-natural, nutritious dog cancer diet cannot help your dog if she cannot digest the foods properly. Digestive enzymes aid digestion and absorption of foods, enabling your dog to get all the nutrients from the foods to help fight cancer.

It has also been found that enzymes provide the potential for less cancer metastasis and recurrence, as well as longer survival times.

Additionally, enzymes can reduce side effects from radiation and chemotherapy.

Digestive enzymes such as Prozyme should therefore be added as a supplement to a dog cancer diet.

Note, however, that enzymes have blood thinning effects and should not be given to dogs with clotting disorders. Also stop giving enzymes to dogs 10 days before surgery and do not resume until the sutures are removed.


Probiotics are important in supporting and strengthening a dog's immune system. The digestive system is the largest immune organ in dogs. However, very often, dogs on medications (such as antibiotics, corticosteroids), under stress, or after surgery are depleted of the "friendly" bacteria that live in the dog's gut. As a result, the good-to-bad bacteria ratio in the dog's gut is upset, greatly weakening the dog's immune system. To strengthen the already weakened immune system of a dog with cancer, therefore, a high quality probiotic supplement is essential.


IP-6 is an extract from the bran of brown rice. Studies have found that IP-6 can help control the spread of tumors by boosting the immune system and increasing the body's natural killer cells. In addition, IP-6 may also be used to prevent cancer since it also possesses antioxidant properties.


Antioxidants remove free radicals from the body system, thereby helping cancer prevention and slowing the growth and the spread of some kinds of cancer.

Some excellent antioxidants are:

  • Vitamins C and E
  • The mineral selenium
  • Green tea
  • Coenzyme Q10

Great Supplement Products
