Cancer is a serious and complicated disease to treat. However, with good nutrition and proper monitoring of its development, cancer can be defeated.

The nutritional needs of a dog with cancer differ from the needs of a healthy dog. If your dog has cancer, he must follow a certain diet controlled by your veterinarian, who must monitor the development of the disease (you can also opt for dog food with cancer that may be better for you and more suitable for your dog).

A well-prepared natural diet can be ideal for your dog. You will be able to control the ingredients used and provide your dog with delicious food that he will love. Choose carefully, because not all food is suitable for dogs. If necessary, consult a professional to calculate the amounts and nutrients you should provide to your dog, in order to achieve a well-balanced diet.

The diet for a dog with cancer may need to vary depending on the severity and progress of the disease. If your dog has cancer and does not get the nutrients he needs, he will look for them in his body’s stores, which can lead to atrophy and muscle weakness, as well as a weak liver, kidneys or other complications.

What should a dog with cancer eat?

The dog’s immune system with cancer is weakened, so he must follow a special diet. Also, cancer therapies, such as chemotherapy or radiation therapy, are aggressive and further weaken his immune system.

If your dog has cancer, make sure you provide him with the nutrients he needs. It is very important that the proteins are of high quality. Make sure his diet contains omega 3 fatty acids and is low in carbohydrates. Carbohydrates in your dog’s diet must be complex, avoid rapid assimilation of sugar.

Simple carbohydrates are especially dangerous for a dog with cancer. You should avoid cereal-based foods, so it is best to use high-quality food, special formulas for his illness or well-balanced natural foods.

Always consult your veterinarian, as your dog’s needs can vary greatly depending on the type of cancer he has.


Quality animal proteins are very important for your dog. Proteins can be from chicken, turkey, cottage cheese, Burgos cheese, eggs, canned sardines …

The three amino acids you need to provide in your dog’s diet are:

Arginine: strengthens the immune system and slows the growth of some tumors.

Glutamine: inhibits tumor growth and helps the intestinal tract.

Melatonin: An antioxidant that eliminates free radicals and contributes to the destruction of cancer cells.

If you are a fan of raw food, consult a veterinarian, because it may be best to cook meat first, because your dog’s immune system is weakened and a bacterial or parasitic infection can be very harmful for him.


A dog’s diet with cancer must be low in carbohydrates, and they must be complex or slowly assimilated, because cancer cells use sugar to multiply. Simple carbohydrates are very harmful for a dog suffering from cancer, because they are quickly assimilating sugars.

Fatty acids.

Unsaturated fats are very useful for dogs with cancer, especially omega 3, which are an effective aid in the dog’s response to chemotherapy. It seems that, in addition to improving the immune system, omega 3 fatty acids can prevent cancer from reproducing.

Fish oil is a good source of omega 3. These fatty acids help reduce tumors.

If your dog does not have a lot of appetite, give him a few smaller portions a day, so that his food will always be fresh, and your dog will eat it better.


Some vegetables or fruits, such as berries, broccoli, zucchini or spinach, contain dog vitamins and much-needed minerals for your dog, so it is important to provide them in sufficient quantities. The fiber contained in vegetables will contribute to good intestinal transit.

Turmeric and ginger.

Turmeric and ginger are very useful for dogs in general, and if they have cancer, they will contribute to a better physical condition of your dog.

Turmeric has two very beneficial ingredients for your dog’s health:

Curcuminoids: are the pigments responsible for the color of turmeric. They are very effective antioxidants. The most famous of these is curcumin.

Volatile oils: responsible for the smell and taste of turmeric. They also have very interesting properties.

Curcumin destroys cancer cells without damaging healthy cells, prevents their proliferation and is effective against metastases. It is also a very powerful natural anti-inflammatory agent.

Among the many advantages of ginger is its anticancer effect, because it reduces the action of free radicals in the body. Ginger extract has been shown to help shrink certain tumors, and giving ginger powder can destroy and kill tumor cells as well as inhibit their growth.

If you opt for vegan dog food, you must take certain precautions.

As you can see, it is very important to know what ingredients the type of food you give to your dog contains. In case you decide to feed your pet thoughtfully, here are some tips on how to properly read and interpret the labels of ready-made dog food. Consult your veterinarian to find out how much you can give to your dog.

How do I prepare a natural diet for a dog with cancer?

Natural food is a good alternative for every dog, but you must prepare it carefully to ensure a balanced diet. In case your dog has cancer, you need to provide nutrients that strengthen his immune system and help him fight cancer cells.

It is important to use quality animal proteins, low in carbohydrates and moderate amounts of healthy fats, as well as low in fiber to maintain the health of the intestinal tract.

The scheme of how this diet can be is as follows:

Day 1: Lean muscle meat (removes all fat), mixed with green leafy vegetables and a source of healthy fat

Day 2: Mixture of lean muscle meat, organ meat, greens and pre-frozen raw meat bones

Day 3: steamed pumpkin or fruit and vegetable puree. Berries, like blueberries, are very good to include in the diet of a dog with cancer.

Day 4: as day 1

Day 5: as day 2

Day 6: as day 1

Day 7: as day 2

The advice we give you here is based on the BARF diet which, among other products, is based on natural ingredients, such as fruits, vegetables or meat. For more advice on natural dog nutrition, contact a nutritionist.

Is a ketogenic diet useful for dogs with cancer?

A ketogenic diet replaces carbohydrates with high-quality proteins and useful fats. Cancer cells metabolize glucose to obtain energy in a different way than healthy cells. Healthy cells can adapt to metabolism and consume ketone bodies instead of glucose, while cancer cells do not. Ketones are produced when the level of glucose in the body is low, so they depend on the availability of glucose.

Therefore, a ketogenic diet (high in fat and low in carbohydrates) is beneficial for dogs with cancer. With this diet, your dog’s body uses fats as fuel, instead of carbohydrates, so that the cancer cells do not have the glucose they need to grow.

If you want to follow this diet, it is very important that you prepare dog food at home and control what you eat.

What supplements should I give my dog if he has cancer?

Digestive enzymes.

Digestive enzymes help digest and absorb food and reduce the risk of cancer metastasis and recurrence. In addition, they can reduce the negative effects of radiation and chemotherapy.

All this contributes to the fact that digestive enzymes are a suitable addition to the diet of a dog with cancer.


Probiotics help strengthen the dog’s immune system. They are living microorganisms that improve the intestinal flora, reducing the presence of harmful bacteria, as they compete with them for resources, making it difficult for them to reproduce and increasing the presence of useful agents.


Antioxidants, such as vitamins A, C, and E, selenium, coenzyme Q10, and green tea, help eliminate free radicals and reduce tumor growth.

Selenium protects the immune system and reduces and prevents cancer, especially in combination with vitamin E. Selenium has been shown to reduce cancer mortality.

Coenzyme Q10, called ubiquinone, is an antioxidant in the body that helps boost a dog’s immune system. Brewer’s yeast can help absorb this coenzyme.

Green tea has less theine than other teas, and you can give it to your dog. For an adult dog, half a cup a day is enough. Green tea contains polyphenols called catechins, whose antioxidant power is greater than that of vitamin C. It is a natural anti-inflammatory agent and has been shown to slow the growth of cancer cells.
