In dogs, tumors affecting the feet can be either benign or malignant. These growths often come as a surprise to the owner, and require attention by a veterinarian. In some cases the tumor may not be visible, and is only discovered during a routine examination by a well-trained veterinarian.

Types
-
There are several types of benign and malignant tumors that can affect the parts of a canine foot, including the toes, bones, paw pads and skin. This includes squamous cell carcinoma, histiocytoma, mast cell tumors and epidermoid carcinoma.
Symptoms
-
The symptoms of a canine foot tumor can vary depending on the type and severity of the tumor. Some tumors may cause bleeding, limping or swelling. Broken nails or solid, raised masses may also be present.
Diagnosis
-
To determine the type of tumor, the veterinarian may perform x-rays and take samples of the tumor. The vet will send the sample to a pathologist, who will determine what type of tumor is present and relay the information to the veterinarian.
Treatment
-
Treatment varies based on the type, number and severity of tumors present. In some cases the tumor itself may be removed, while in other cases amputation of the leg may be necessary. Chemotherapy and radiation therapy are also options if the tumor has begun to spread.
Prognosis
-
Canine foot tumors will have a varied prognosis. Some dogs that undergo removal of the tumor, foot or entire leg often adapt well to being three-legged and continue to live out their lives. If spreading has occurred, the prognosis may be more guarded.
