You said "big knot" and I don't think Cozmo is micro-chipped yet is he? So I don't think this is it, but I thought I'd throw it out there.
You can feel Coby's micro-chip. I felt it and asked the vet about it. He said that sometimes they migrate back nearer the surface and can be felt. The groomer felt it last time and asked me if he was micro-chipped. She said that it does happen and she has found a few and just wants to make sure that's what it is.
Whatever it is, I hope it's nothing serious............ |
