Just noticed this bump on my dogs face and it’s bleeding. What could it be? Pet's info: Dog | Boston Terrier | Male | neutered | 40 lbs

This lump on Damien's face could be a cyst, a benign tumor, or a malignant tumor. In a dog his age, there's always a chance a lump could be malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call tomorrow to make him an appointment. Best of luck.

Hi, and thanks for your question. This lump/bump/growth should be ideally examined by your local vet to have a diagnosis established. Your vet may want to perform an FNA (fine needle aspiration) or a biopsy to sample the bump and determine its underlying nature. Differentials would include skin cysts, infections, benign or more malignant type of tumors.

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors.
