Your dog will probably love this attention and may think it’s a massage. Different types of skin cancer look different. With one common type, Cutaneous Squamous Cell Carcinoma, a bleeding sore appears that will not heal with creams or antibiotics. These sores are generally red and may look like an ulcer.

In fact, some of the most common types of skin cancer in dogs, such as Squamous cell carcinoma, do require surgical removal but do not usually require chemotherapy or radiation afterword. [6] X Research source
Sometimes a larger piece of the tumor (biopsy) or the entire tumor will need to be examined in order to find a correct diagnosis. [7] X Expert Source Ray Spragley, DVMVeterinarian Expert Interview. 31 March 2021.
Each case is different and only your veterinarian can help you to decide the best course of action.
Many times mast cell tumors itch and the surrounding skin is reddened. Mast cells are blood cells that are part of the immune system and are produced in response to allergens and inflammation. [9] X Research source Why some mast cells develop into tumors is not understood but they are more likely in dogs from 8-10 years of age and in certain breeds (pugs, boxers, Boston terriers, and Rhodesian ridgebacks).

Melanomas occur more frequently on the head and front legs of older dogs. [11] X Research source Schnauzers and Doberman Pinchers have a high rate of this type of tumor. They are typically raised dark colored lumps. The ones in the mouth can interfere with eating, cause the dog to drool or bleed from the mouth and cause bad breath. Toenail melanomas can cause the toe to swell, the toenail to fall off, and make the dog limp. Occasionally melanomas are NOT dark colored and will be the same color as the skin surrounding them.
Dogs with little hair or light colored dogs can get sun-induced skin cancer, but this isn’t very common. As like the other types of skin cancer it is more common in middle-aged to older dogs. [12] X Research source Squamous cell carcinomas can look like raised lumps with ulcerated skin.
