Cancer, a word that brainstorms your imagination with images of those loved ones losing the spring of their lives while going through endless treatments; motivated by the hope that they might recover one day. This is what cancer looks like in humans, but what about dogs?

What are the types of dog cancer?

Dogs can also suffer from cancer as humans do and it’s quite the same horrible experience. There are several types of this fatal disease:

Bone cancer

Osteosarcoma is probably the most common type of cancer in dogs. It affects old large dogs aggressively. Dogs who suffer from this horrible disease usually surrender to it.

Skin cancer

MCT’s or mast cell tumor is common in dogs. They cause ulcers and lesions that may spread easily. If you find a firm mass on your dog’s legs, mouth or chest, it can be a soft tissue sarcoma.


This is the most common type of them all. It affects the lymph tissue and, if it progresses too far, might a hurt the liver, spleen, lymph nodes and the bone narrow.

Mouth and throat 

Several types of cancerous tumors may occur in your dog’s mouth and throat. Thorough treatment is an obligation to eliminate them.

Blood vessel

Hemangiosarcoma begins at the lining of blood vessels and may spread to other part of your dog’s body such as heart, liver skin and spleen. Both male and female dogs may contract it as they age.

Breast cancer

50% of cancerous tumors found in female dogs are mammary tumors. This disease is 3 times more common in dogs than in humans. It affects some breeds such as German shepherd, pointers and English spaniels.
