My 7 or 8-month old mixed breed puppy, Jack, is going to see his vet next week. He's got a marble size growth in the thigh muscle of his right rear leg. The other one doesn't have it. Maybe a lymph node; but why then, is it swollen. I can roll it. I am wondering if his Avid chip has migrated, which can happen.
I'm worried.
He's such a dear baby boy.
