A diagnosis of cancer in your dog can be a stressful and emotional experience. As a pet owner, you naturally want to do everything possible to support your dog's health and well-being during this challenging time. Nutrition plays a vital role in managing canine cancer, influencing treatment outcomes, and improving your dog's quality of life. This article delves into the dietary considerations for dogs with cancer, providing guidance on how to nourish your canine companion through their cancer journey.
Understanding the Nutritional Needs of Dogs with Cancer
Cancer can significantly impact a dog's nutritional status. The disease itself, as well as treatments like chemotherapy and radiation, can lead to various side effects that affect appetite, digestion, and metabolism. Some common challenges include:
- Hyporexia or Anorexia: Decreased or complete loss of appetite.
- Cachexia: Severe weight loss and muscle wasting.
- Changes in Metabolism: Cancer cells utilize energy differently than normal cells, potentially leading to energy imbalances.
- Direct Effects of the Tumor: Tumors in the mouth, throat, or intestinal tract can make eating, swallowing, or digesting food difficult.
- Chemotherapy Side Effects: Chemotherapy drugs can alter the sense of smell or taste, cause nausea, vomiting, diarrhea, or food aversions.
- Radiation Therapy Side Effects: Radiation to the head or neck can cause changes in saliva production and inflammation of the mouth, tongue, and esophagus.
Addressing these nutritional challenges is crucial for maintaining weight, supporting the immune system, and improving treatment outcomes.
Key Dietary Principles for Dogs with Cancer
While there is no one-size-fits-all diet for dogs with cancer, some general principles can guide your feeding decisions:
- High-Quality Protein: Protein is essential for maintaining muscle mass, which is particularly important in preventing or combating cancer cachexia. Choose high-quality, digestible animal proteins from sources like grass-fed beef, guinea fowl, or chicken. Ensure that the meat comes from healthy USDA-Inspected animals being used for human consumption. Organs like the liver are some of the most nutritious parts of an animal and contain 10 to 100 times the nutrients found in a serving of muscle meat. The egg itself is a highly-digestible complete protein, meaning it has all nine amino acids the body needs from food.
- Healthy Fats: Fats provide a concentrated source of energy and are less likely to be used by tumor cells for energy compared to carbohydrates. Consider nutrient-dense fruits high in healthy fats and fiber.
- Low Carbohydrates: Since cancer cells preferentially use carbohydrates (especially glucose) as an energy source, limiting carbohydrate intake may theoretically reduce the fuel available for tumor growth. However, it's important to note that there is no proven benefit to completely eliminating carbohydrates, and some carbohydrate sources provide valuable vitamins and minerals.
- Omega-3 Fatty Acids: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are omega-3 fatty acids found in fish oils that may have anti-inflammatory and anti-tumor effects. Brimming with Omega 3s (EPA & DHA) and an antioxidant with radical scavenging abilities hundreds of times more powerful than vitamin C, vitamin E, or beta-carotene.
- Antioxidants: Antioxidants help protect cells from damage caused by free radicals, which can be beneficial in supporting overall health. The highest amount of antioxidants among any fruit, blueberries help counteract oxidative stress to decrease inflammation.
- Fiber: A healthy source of fiber to encourage regular gi mobility.
Foods to Include in a Canine Cancer Diet
Based on these principles, here are some specific foods that can be beneficial for dogs with cancer:

- Lean Meats: Chicken, turkey, fish, and lean beef provide high-quality protein.
- Fish Oil: A good source of omega-3 fatty acids.
- Eggs: A highly digestible source of complete protein.
- Certain Vegetables: Broccoli, sweet potatoes, beets, pumpkin, and dark berries (blueberries, blackberries) are rich in vitamins, minerals, and antioxidants.
- Coconut Oil: Contains fatty acids and plant sterols, may block absorption of cholesterol, reduces inflammation and high in antioxidants.
- Organ Meats: Liver is packed with nutrients.
- Spirulina: Rich in unique phytonutrients like phycocyanin, polysaccharides, and sulfolipids that boost the immune system.
- Kelp: Incredibly rich in vitamins and minerals and is one of the best natural sources of iodine.
Foods to Limit or Avoid
- Processed Foods: Kibble goes through four different cooking processes that reach 400℉, eliminating almost all nutrients that the ingredient had in its raw state.
- Corn and Wheat: Corn is commonly used as a filler for commercial kibble companies, as it is inexpensive and easily accessible. Corn is used as a plant-based protein and isn’t as digestible or bioavailable for carnivores.
- Artificial Dyes: Artificial dyes are used in pet foods to add color to brown kibble in an attempt to give them a more desirable and aesthetically pleasing color.
- Rendered Fats: Rendered fats in kibble are typically low quality and from unidentifiable animals. They may also contain fat-soluble toxins that can be harmful when consumed.
- Raw Foods: It is important to avoid feeding raw diets or treats to pets with cancer. Raw meat, eggs, and milk carry high risk of bacterial contamination with Salmonella, Listeria, E. coli, Campylobacter, and other potentially dangerous bacteria.
Commercial vs. Home-Prepared Diets
You have the option of feeding your dog a commercial diet specifically formulated for dogs with cancer or preparing a home-cooked diet.
- Commercial Diets: Look for diets that are designed to support dogs with cancer by nourishing the body with clean proteins, low carbohydrates, and antioxidant-rich whole foods. Always check the AAFCO statement on the label to ensure that the food is complete and balanced for your dog's life stage.
- Home-Prepared Diets: These diets allow for greater control over ingredients and can be tailored to your dog's specific needs and preferences. However, it's crucial to consult with a board-certified veterinary nutritionist to ensure that the diet is nutritionally complete and balanced. You can’t compromise on using clean, wholesome foods like organic produce and pasture-raised meats.
Supplementation
While a well-balanced diet should provide most of the nutrients your dog needs, certain supplements may be beneficial:
- Omega-3 Fatty Acids: If your dog's diet is not already high in omega-3 fatty acids, consider adding a fish oil supplement.
- Antioxidants: Supplements like mixed tocopherols, a natural preservative, in every diet to keep it shelf-stable and also provide additional antioxidants.
- Probiotics: Probiotics have been defined as “live micro-organisms which when administered in adequate amounts confer a health benefit on the host” by the joint Food and Agriculture Organisation (FAO) and the World Health Organisation (WHO).
It's important to discuss any supplements with your veterinarian before adding them to your dog's diet, as some supplements can interact with cancer treatments.
Tips for Encouraging Your Dog to Eat
Even with the best diet, some dogs with cancer may have difficulty eating. Here are some tips to encourage your dog to eat:
- Offer Small, Frequent Meals: It is best to offer multiple small meals a day to assure the food is fresh.
- Warm the Food: Warming canned food to body temperature can help increase the aroma of the food.
- Add Flavorings: Dogs like the taste of sweetness and salt. If advised by your veterinarian, these can be added in small amounts to the dog food. Its cheesy taste is considered a palatability enticer.
- Make Eating Easy: Be sure the food bowls are easily accessible. You may want to place multiple bowls around the house. Be sure your dog can access the food.
- Consider Appetite Stimulants: There are appetite stimulants that may be prescribed, as well as anti-nausea medications and antacids that can be useful in pets that are not eating well.
- Chicken Bone Broth: Hydrate your dog’s food with chicken bone broth (no sodium) as a nutritious and enticing way to add moisture and flavor.
- Unseasoned Boiled Chicken: Put a sprinkle of plain shredded chicken in with their food and mix throughout.
The Importance of Veterinary Guidance
It is extremely important to consult with your veterinarian or a board-certified veterinary nutritionist to develop an individualized dietary plan for your dog. They can assess your dog's specific needs, taking into account the type and stage of cancer, treatment plan, and any other underlying health conditions.
