11 yr old Female Lab is in VERY good shape. Walks/runs of 6+ miles not a problem. Just noticed lump on inner right rear hock. She does not favor it or limp. Freaked out by what I saw online. I can provide pictures.
Agree with Edp go to the vet. Don’t use Dr.Google. Any lump should be investigated and there are so many things it could be. The fact she isn’t limping would probably rule out bone cancer as that is very painful. Keep us posted.
