Causes of Mast Cell Tumors

Mast cell tumors (MCTs) are one of the most commonly seen cancers in dogs. While the exact cause of mast cell tumors is unknown, there are certain risk factors that can increase a dog’s chances of developing the condition. These risk factors include age, gender, breed and environmental exposures to certain pollutants or chemicals.

In regards to age, dogs over 10 years old tend to be more at risk than their younger counterparts. Males also seem to be more likely to develop mast cell tumors than females. Certain breeds, such as Boxers, Bulldogs and Boston Terriers are genetically predisposed to developing MCTs. Exposure to certain environmental pollutants can also increase a dog’s risk of developing mast cell tumors.

The best way for pet owners to reduce the risk of their pup’s exposure these risk factors is by feeding them an appropriate diet for their breed and age group. A high-quality diet designed specifically for canine cancer patients can help reduce their risk of developing health issues related to poor nutrition that may lead to cancer in the first place.

Symptoms of Mast Cell Tumors

Mast cell tumors (MCTs) are one of the most common types of skin tumors in dogs. Symptoms of mast cell tumors often depend on the size and location of the tumor, but may include a firm lump or mass on your dog’s skin that may cause itching, licking, or hair loss around the affected area. The mass may also be visible when your dog is lying down, and it can range from small and smooth to large and irregularly shaped.

For dogs with mast cell tumors, diet is an important factor in helping reduce symptoms associated with MCTs. An appropriate diet can help manage pain and inflammation while promoting overall wellness. The best diet for dogs with MCTs should be high in antioxidants, omega-3 fatty acids, probiotics, and other anti-inflammatory ingredients that can help reduce inflammation caused by MCTs. A raw food or grain-free dog food with limited carbohydrates is ideal for MCT-related diets as these are known to reduce inflammation. Additionally, a balanced multivitamin supplement will ensure your dog receives proper nutrients during treatment.

Diagnosing Mast Cell Tumors

Mast Cell Tumors (MCTs) are the most common type of skin cancer found in dogs. A diagnosis of mast cell tumors usually begins with a physical examination, followed by a series of tests to confirm the diagnosis. Diagnostic tests may include: blood work, urine analysis, an abdominal ultrasound, biopsy, and/or X-ray.

Once your veterinarian has confirmed that your dog has mast cell tumors, dietary changes may be necessary to help counteract the disease and promote overall health. Generally speaking, a low-fat diet is best for dogs with MCTs; however, specific breed-specific diets can also be recommended depending on the individual. Additionally, supplements such as omega-3 fatty acids (EPA and DHA) are also beneficial for dogs with MCTs due to their anti-inflammatory properties. Lastly, probiotics can help support digestion as well as gut health—both important for maintaining overall body health and well-being.

Treatments for Mast Cell Tumors

Treatments for mast cell tumors in dogs can vary depending on the severity and type of tumor. Traditional treatments of chemotherapy and radiation may be recommended by your veterinarian. However, there are additional treatments that many veterinarians may suggest, including dietary changes to manage the disease and improve a dog’s quality of life.

Dietary changes for dogs suffering from mast cell tumors typically involve switching to a high-quality diet that has anti-inflammatory properties or specific ingredients that may benefit the patient. These diets should be rich in:

  • Antioxidants
  • Omega-3 fatty acids
  • Probiotics
  • Vitamins A and E
  • Glucosamine and chondroitin sulfate
  • Other supplements found beneficial to mast cell tumors

The goal is to provide the dog with a balanced and nutrient-rich diet without aggravating existing symptoms or compromising their overall health.

The Best Diet for Dogs with Mast Cell Tumors

Dogs with mast cell tumors (MCTs) can benefit from a diet tailored to their specific needs and goals. From controlling weight to encouraging a healthy immune system, the right food for your pet can make all the difference.

Let’s explore some of the best diet options for dogs with mast cell tumors:

Avoiding Certain Foods

When dogs are diagnosed with mast cell tumors, special care needs to be taken with their diet. Dogs with mast cell tumors should avoid certain foods, as they can potentially make the tumor worse.

Refined carbohydrates (such as white bread and pasta) should be avoided, as well as processed meats like hot dogs and bacon, which contain high levels of fat and preservatives. It is also important to avoid soy proteins, which some research suggests can lead to an increased risk of cancer in dogs.

Finally, it is important to feed a diet that is rich in antioxidants and vitamins A and E, which have been shown to have beneficial effects on the tumor cells. Feeding fresh fruits and vegetables can help provide these nutrients, while also avoiding adding too much unnecessary sugar into your dog’s diet.

Adding Supplements

Adding supplements to your dog’s diet if they have mast cell tumors is important as it helps to ensure that your dog is getting the right amount of essential vitamins and minerals. The most beneficial supplement for dogs with mast cell tumors is omega-3 fatty acids, as they are known to reduce inflammation and bolster immunity, which can help to reduce tumor growth.

Additionally, adding probiotics can help improve gut health and immune function, while adding vitamin E can help protect cells from damage due to radiation or chemotherapy. Furthermore, adding a multivitamin will ensure your pet has access to any missing vitamins or minerals that may not be available in their diet.

Ultimately, all pets are different, so it’s important to consult with a veterinarian before making any changes to your pet’s diet to determine the best course of action for their specific needs.

Feeding for Optimal Health

Feeding for optimal health of your dog is key when dealing with a Mast Cell Tumor. In the past, most dog owners would look to commercial pet food as the best option. However, recent studies have shown that fresh, unprocessed foods provide a more balanced and comprehensive diet.

This includes fresh wholefoods such as lean proteins and complex carbohydrates from whole grains or vegetables. Additionally, adding in natural supplements such as Omega 3 fatty acids, vitamins and minerals can also help support overall health through nutrition.

It’s important to note that while no single diet is right for every dog with a Mast Cell Tumor, avoiding processed foods and opting instead for fresh wholefoods can help improve their nutrition and quality of life.


Ultimately, the best diet for dogs with mast cell tumors is one that is tailored to their specific needs. If a dog has a mast cell tumor, they may benefit from diets that are high in fiber, low in fat and high in antioxidants. Additionally, it’s also important to ensure that your pet is getting enough essential fatty acids and protein to help support their immune system and decrease inflammation.

Above all, make sure to consult with your veterinarian before making any dietary changes for your dog with mast cell tumors. Your vet can provide advice about what kind of diet will be most beneficial for your pet’s particular condition and stage of cancer.

By following these general guidelines and paying close attention to the specific needs of your pet, you can ensure that they have the best chance possible of fighting off mast cell tumors.
