Just like humans, dogs too can get cancer. In fact, cancer in dogs is a very common illness, and recent statistics have shown that one in approximately every 150 dogs is diagnosed with the dreaded cancer disease. Thus, pet parents need to know about this dangerous disease, and we are going to do exactly that. Here’s everything you need to know about cancer in dogs. We’ll begin with the types, and then move on to the signs, and we will close it out with the treatment options.

Types of Dog Cancer

Numerous types of cancer can affect your furry pal. We though have mentioned the highly common ones. Let us look at them briefly.

1. Bladder Cancer

This type of cancer takes time to develop and signs may only show up after three to six months. Certain dog breeds like the Beagle, West Highland Terrier, Scottish terrier, Sheltie, etc. are susceptible to this type of cancer.

2. Brain Tumors

Tumors can grow in the brain all of a sudden and can be very dangerous. The longer they stay, the deadlier they become. Thus, it is important to try and get rid of them as soon as they are detected.

3. Hemangiosarcoma

This type of cancer generally affects dogs that enter adulthood and is a cancer of the blood vessels. Dog breeds such as golden retrievers, German shepherds, Skye terriers, etc are prone to such a disease.

4. Lymphoma

Known as the cancer of the lymph nodes that attack the dog’s immune system, Lymphoma is a very common cancer in dogs. This type of cancer can affect any dog breed and at any age.

5. Mammary Gland Carcinoma

Female non-spayed dogs are at a higher risk of getting diagnosed with Mammary Gland Carcinoma. This is a cancer of the mammary glands and can be prevented during the earlier stages of the dog’s life.

6. Mast Cell Tumor

This kind of cancer can develop anywhere on the dog’s body and is more likely visible as a skin lesion. These cells are immune cells that range from benign to highly aggressive tumors. Such tumors can spread and can be very fatal when they do.

7. Melanoma

Dogs with pigmented skin are at risk of melanoma cancer. Such cancer can develop in an around the mouth, eyes or footpad areas. Miniature Schnauzers, Doberman Pinschers, Scottish terriers, etc. are at a higher risk of melanoma cancer.
