A lump often means a tumor. Lots of dogs get them, sometimes on their belly, under their arms, and sometimes even on their faces.

I'm not a vet. These are basic questions. The answers may help someone more qualified to answer.What kind of lump? How large? Where?Is your dog in pain?As someone else mentioned, a lump could be a tumor. Some dogs/breeds can get 'lipomas' which are fatty, benign tumors. These typically would not cause your dog to limp. A lump could also be fluid from a soft injury like a sprain (have you ever sprained your ankle and it swelled up?), or, if it's hard, it could be a broken bone.My first recommendation would be to take your dog to a vet as soon as you can tomorrow.
