My dog has a lump on her stomach along with a bite mark next to it. What is this. Should I be concerned?

Good morning. Lumps or swellings can occur for a variety of reasons in dogs. I am not able to see a bite mark in the picture, but if there is a wound associated with the swelling, this could indication an infection or abscess has formed. Other potential causes for a swelling would be inflammation secondary to insect bites, a cyst or even a tumor. In the picture, it appears that the lump may be close to a nipple. Since Zoey is not spayed, she is at a higher risk for developing mammary cancer and this location would fit with a growth within the mammary chain. I would recommend that you have Zoey seen by your veterinarian so they can better evaluate what may be going on. They will perform a thorough examination and will likely recommend a fine needle aspirate of the lump. This is a procedure in which a small needle is used to collect cells from a lump to better determine what is causing it. This typically does not cause much pain and can be very helpful in determining what may be going on.
