Dogs with cancer often have special dietary needs that must be met if the animal is to remain healthy. In many cases, a balanced diet comprised of high-quality lean proteins, beneficial fats and carbohydrates, as well as essential vitamins and minerals, can be tailored to the individual’s specific needs.

In this article, we’ll take a look at the best diet for dogs with cancer, as well as how to make sure your pet is getting the nutrition they need.

Understand the importance of a cancer diet for dogs

Having a dog with cancer can be a difficult time for both the pet and their owner. As part of treatments, doctors may suggest making dietary modifications to help improve their health. There are certain elements that are key to having an effective cancer diet for dogs, such as antioxidants and certain vitamins and minerals.

Antioxidants may reduce the progression of cancer in dogs by slowing down the rate at which cells grow, divide and age. Vitamin D, selenium, omega-3 fatty acids and zinc are also important for helping with cellular health. Foods high in these nutrients include sources like salmon, sweet potatoes and spinach. Additionally, carbohydrates should make up the majority of their diet as they provide energy while being easier to digest than other sources of energy like fats.

It is important to understand that no single food will cure cancer in pets; however providing a healthy balanced diet can support them on their journey toward recovery from this disease.

Learn the basics of a cancer diet for dogs

For pets with cancer, one of the most important components of treatment is a carefully tailored diet. It is best to talk to your vet or seek the advice of a board-certified veterinary nutritionist (ACVN) for specifics. A general overview, however, will provide you with valuable information on how to tailor your pet’s dietary needs around their condition.

Generally for dogs with cancer, it is recommended to feed them a higher-protein and higher-fat diet with moderate carbohydrates and high levels of omega 3 fatty acids and antioxidants. Additionally, it can be beneficial to ensure that the food does not contain artificial additives or preservatives as these compounds may interfere with their cancer treatments. Finally, make sure that your pet gets plenty of fresh water each day as this will help keep them well hydrated and boost immune system health.

Nutritional Requirements

Feeding your beloved furry friend a nutritious diet is an important part of their fight against cancer. A specifically formulated diet tailored to a dog’s individual nutritional needs can help to boost their immune system and give them the energy to fight the disease.

Let’s look at the key nutritional requirements for dogs with cancer:


Protein is an essential macronutrient for dogs of all ages and stages of life, and it is especially important for dogs facing cancer. Protein helps the body to repair damage caused by cancer and its treatments, as well as helping to strengthen the immune system. It can also help to regulate hormones, which can also be affected by cancer.

Ideally, dogs with cancer should receive protein from multiple sources that are high quality and easily digestible. Quality proteins include:

  • Fresh lean meats (like chicken or turkey)
  • Eggs
  • Fish
  • Plant-based proteins like legumes or quinoa

Nuts, dairy products (like cheese or yogurt) can also provide protein for your pet’s diet but should be given in moderation due to their high fat content. If your dog is older or has a reduced appetite due to chemotherapy or other treatments, try incorporating higher quality cans foods into his diet that contain more easily-digested proteins such as lamb or salmon. Always talk to your veterinarian prior to making any changes in your pup’s diet plan.


Carbohydrates are an important energy source for dogs with cancer and help to fuel their bodies. The best sources of carbohydrates for dogs with cancer are complex carbohydrates like whole grains, legumes, and root vegetables.

These types of carbohydrates contain beneficial vitamins, minerals, and antioxidants that can help boost the immune system and fight off cancer cells. When choosing carbohydrate sources for a dog with cancer, look for whole-grain options like brown rice or sweet potatoes that are minimally processed. Avoid refined white flours and sugars as they can cause inflammation in the body which can worsen a dog’s cancer symptoms.

Allowing your dog to eat small amounts of cooked oats or barley on occasion is also beneficial as these grains are high in dietary fiber which helps aid digestion.


Fats are important for a dog’s diet, especially for those with cancer. Fats provide energy and support healthy skin and coat. Sources of fats in a dog’s diet should come from unsaturated fatty acids such as omega-3s and omega-6s, which are found in cold-water fish, flaxseed, chia seeds and nuts. Avoid feeding canola or vegetable oil to dogs with cancer as they contain trans fats, which can contribute to inflammation in the body.

Other sources of fat may include:

  • Lean meats such as chicken or turkey;
  • Eggs;
  • Low-fat cheese;
  • Yogurt;
  • Avocado;
  • Olive or coconut oil.

It is important to feed your pet small amounts of these foods regularly throughout the day so as not to overload their body at once. These high-fat foods also help keep your pet feeling full for longer periods of time.

Vitamins & Minerals

Vitamins and minerals are essential for overall good health. A diet rich in these micronutrients is especially beneficial for dogs who have cancer as they can help support their immune system and might even reduce tumor growth.

The primary vitamins and minerals needed in a canine cancer diet are vitamin E, Vitamin B complex, omega-3 fatty acids, zinc, selenium, iron and copper.

  • Vitamin E is an antioxidant that helps keep cells healthy in the face of free radical damage. It can be found in animal sources like liver or eggs as well as plant sources such as almonds, sunflower seeds and spinach.
  • Vitamin B complex helps the body effectively use energy from foods while omega-3 fatty acids support a healthy inflammatory response.
  • Zinc helps with wound healing and is found in beef, lamb or pumpkin seeds while selenium boosts immunity which can be sourced from Brazil nuts.
  • Iron carries oxygen through the body which is found in beef or organ meats such as heart or liver while copper supports red blood cells development through its intake of beef liver or lentils.

Food Types

When it comes to providing a healthy diet for your canine companion dealing with cancer, there are a few different food types to consider. It’s important to select foods that are high in protein and low in carbohydrates. A higher protein diet helps give the body what it needs to fight off cancer, while a lower carbohydrate diet helps reduce the risk of insulin spikes that can be toxic to cancer cells.

Let’s take a look at some of the different food types that can help your dog fight cancer:

High-Quality Protein Sources

When it comes to feeding your dog a healthy diet – especially if they have cancer – it’s important to focus on high-quality proteins. Protein is an essential building block of the body and plays a key role in fighting illnesses like cancer.

When selecting protein sources for your pets, look for lean cuts that are free from additives and preservatives. Some examples of high-quality protein sources for dogs who have been diagnosed with cancer include:

  • Lean meats such as turkey, chicken, beef, and salmon.
  • Eggs or dairy products like cottage cheese.

However, to ensure proper digestion and nutrient absorption, cooked proteins are always recommended over raw ones. Additionally, try adding green leafy vegetables such as spinach or kale for extra nutrition.

Healthy Fats

Healthy fats are an important part of a dog’s diet when they have cancer. Not only do healthy fats help keep your pup’s coat and skin healthy, but also help to combat inflammation, which is one of the main causes of cancer in dogs. Healthy fats should make up about 10-15% of a dog’s daily caloric intake.

Examples of healthy fats for dogs with cancer include:

  • Fatty fish like salmon, sardines and anchovies
  • Coconut oil
  • Flaxseed oil
  • Avocados
  • Nuts like peanuts and walnuts

These foods can be served raw or cooked in moderation. It’s important to consult with your veterinarian before making any drastic changes to your pet’s diet to ensure that the diet you are providing is safe and appropriate for their specific needs.

Complex Carbohydrates

Complex carbohydrates are an important part of a healthy diet for dogs with cancer. Complex carbohydrates, or “macronutrients”, are essential for providing energy and helping the body to absorb other nutrients. They also help fight against other illnesses and can even be used as an energy source for healthy cells in the body.

Complex carbohydrates should be included in the meal plan for dogs with cancer because they provide dietary fiber that helps to reduce inflammation and keep the digestive system functioning properly.

Complex carbohydrates can be found in:

  • Whole grains such as oats, barley, brown rice, quinoa, buckwheat, wheat bran and wheat germ;
  • Legumes such as beans, lentils and peas;
  • Starchy vegetables such as potatoes;
  • Root vegetables such as sweet potatoes;
  • Nuts and seeds;
  • Fruits such as apples and bananas; and
  • Dairy products.

Feeding foods rich in complex carbohydrates can help improve overall health when combined with high-quality proteins like chicken or fish.

Calcium & Phosphorus

Calcium and phosphorus are essential minerals for dogs, especially for those with cancer. Dogs with cancer often lose their appetite, which can result in weight loss. As such, it is important to feed them a diet that will provide them with the nutrients they need to stay healthy.

Calcium and phosphorus play an important role in bone health and muscle contractions, so it is crucial that they are included in your dog’s diet. The best way to ensure your pup is getting enough of these minerals is to feed them a balanced diet that includes foods high in both calcium and phosphorus such as dairy products, eggs, fish, or meat.

Additionally, if your dog requires additional supplementation due to cancer treatments or lost appetite you can provide it through adding supplements or natural sources such as bones or fish oil.

Diet Recommendations

Cancer in dogs can cause weakened immunity and energy levels, so it’s important for pet owners to provide them with the right nutrition. Diet recommendations for dogs with cancer should include high-quality, protein-rich food that is easy to digest.

Let’s take a closer look at dietary recommendations specifically for dogs with cancer:

Commercial Dog Foods

When it comes to feeding dogs with cancer, commercial dog foods are an important part of the diet. Commercial dog foods offer a balanced and complete diet for your pet and provide the essential nutrients needed for recovery.

When selecting a dog food, look for one that is specifically labeled “for dogs with cancer” or “complete and balanced nutrition for dogs with cancer”.

There are many brands available that offer specially-formulated diets for canines suffering from cancer.

When selecting a commercial dog food, focus on high-quality ingredients such as animal proteins, fruits, vegetables, whole grains, vitamins and minerals. Avoid any fillers and preservatives that may be found in low quality dog foods. Additionally, avoid foods with added dyes or artificial flavors as these additives can further increase the risk of health issues. Lastly, check the label to make sure the product meets all of your pet’s nutritional needs and requirements before purchasing it.

Homemade Diets

Homemade diets are a great way to ensure that your pet is getting the best nutrition. Homemade diets provide a balance of nutrients, so long as the diet consists of lean proteins and carbohydrates, healthy fats, fiber, vitamins and minerals. These types of diets also offer more flexibility to adapt to illness or chronic conditions like cancer in your pet.

It’s important to work with a trusted veterinarian who can help you craft the right combination of homemade foods for your pet’s specific needs. For maximum nutrition value and quality control, homemade meals should be carefully planned with your vet’s guidance and monitored regularly.


The best diet for dogs with cancer should include a multitude of essential vitamins and minerals. Vitamins are important as they regulate normal metabolic processes, provide energy, and help maintain healthy cells in the body. Furthermore, supplementing with essential fatty acids, omega-3s and omega-6s, can help reduce inflammation that is often caused by cancer.

Other dietary supplements that can be beneficial for dogs with cancer include:

  • Probiotics
  • Antioxidants such as green tea extract, turmeric extract, and Coenzyme Q10 (CoQ10)
  • Herbs such as milk thistle and astragalus root powder
  • Medicinal mushrooms like reishi, maitake, cordyceps sinensis and turkey tail mushroom powder

Consult your veterinarian for specific recommendations about the appropriate amount of each supplement to give your dog.

Feeding Tips

When considering the best diet for a dog with cancer, it is important to ensure that the diet is nutrient-dense and contains a balance of amino acids, fatty acids, vitamins, minerals, and carbohydrates. Additionally, the optimal diet should provide your dog with the necessary calories and proteins to maintain their bodyweights while also treating the symptoms of cancer.

In this article, we will discuss some tips on feeding your dog with cancer:

Small, frequent meals

Cancer can have a negative impact on your dog’s appetite, which can lead to them not getting enough nutrients. If your dog has cancer and is having trouble maintaining their weight or eating enough, you may want to consider feeding them smaller meals more frequently throughout the day.

Smaller meals are easier for a sick dog to digest, and it will help them get more nutrition in their body. Feeding your dog small meals every few hours will also help you keep an eye on how much food they are taking in and watch for any signs of an upset stomach or distress.

Additionally, some people recommend adding high-protein supplements such as meat or eggs to help boost energy levels. Be sure to discuss these ideas with your vet before making any changes to your pet’s diet plan.

Avoiding table scraps

When it comes to caring for a dog with cancer, avoiding table scraps is important. Table scraps may contain ingredients that are difficult to digest or are high in fat, which can make your pet’s cancer worse. It is best to feed your pet a diet that consists of only the food recommended by its veterinarian. This food should be designed specifically for cancer patients and should also be high in protein and low in carbohydrates.

Additionally, if you are giving your pet supplements, make sure they are medically approved supplements by consulting with the vet first, as some supplements may interfere with treatment options like chemotherapy or radiation therapy.

Lastly, remember to monitor your dog’s weight throughout their treatment plan and adjust food intake as needed based on their energy levels and nutrition requirements.

Monitoring food intake

Monitoring your dog’s food intake is essential when they suffer from canine cancer. A healthy diet is critical to helping your dog fight the disease and maintain their strength, so you should have a close eye on exactly what and how much they’re eating at each meal.

You may even want to consider having a percentage scale where you can measure the exact amount of food that is given to your pet with each meal. This will help you ensure that they’re getting enough nutrition and that they’re not overeating or under-eating. It will also help you make sure that you are giving them the proper type of food for their condition, as well as ensuring that no foods are being left behind in the bowl by accident.

Additionally, make sure to provide plenty of water for your pup, as hydration can be just as important during this time.
