There are several different types of malignant mammary tumors, with carcinomas being the most common. Carcinomas arise from epithelial (skin) cells, tubules of the mammary glands, or other cells found in the mammary chain. The size of the masses and their appearance may vary, but they are usually firm and nodular. Occasionally, the skin over the mass may ulcerate (open) and bleed, and the affected area may feel warm to the touch and become painful. Detecting and treating these tumors when they are small, and before spread has occurred, will provide your dog with the best chance for long-term control.

Dental malocclusion occurs when the upper and lower jaw lengths are considered normal but one or more teeth are out of normal alignment. This article explains the common forms of skeletal and dental malocclusion seen in dogs.

Mast cell tumors are most common in the skin of dogs and may appear red, ulcerated, or swollen. They can be itchy and can fluctuate in size. Tumors can range from lower-grade, with minimal spread, to higher-grade, with a high risk of local invasion. Treatment usually involves surgical removal and may require supportive treatment including chemotherapy, radiation therapy, and therapy to target the mutation that instigated the tumor.

Mastitis is a term used to describe inflammation of a mammary gland. In most cases, mastitis is caused by a bacterial infection. Trauma to the mammary gland, or prolonged periods of milk accumulation without milk removal, can lead to inflammation within the mammary gland.
