She’s a 1 year old cocker spaniel. The lump appeared today so I took her back to the vets this afternoon. The vet said it was a hernia caused by internal sutures splitting, and took her stright into surgery. They called us to say it wasn’t a hernia and she might have mrsa or an infected mammary gland.they said that she might not make it.the wife and our 4 children are in tears. Am I wrong in thinking that if either of these are true, that it’s the vets fault.
