Aaawww.. poor little fella.
Maybe the howling was because of a reaction to his pain meds?? I know when we had Maggie spayed we were petrified because for the first 24 hours she was home it was like watching a zombie-dog. Maggie was no longer present! It was just so scary...
Paid meds can do funny things ..... and wow 3 hernias means a lot of stitches! You wait, in 2 days time, you'll be telling us how difficult it is to keep Echo as quiet and still as the vet told you he has to be!!!!
((((Hugz)))) for you and for baby Echo
