Poor baby. Lots of cuddles and treats are in order. It happened to one of mine a while back and it makes for a worried mum and sulky pup doesn't it? Good luck and get well soon.
Glad the op went well and that she's back home with you. We've gone through this several times due to people dumping glass in a stream! I found manuka honey (recommended by my vet) really helped the healing process.
I hope you're both ok, our furry friends are a great worry to us because we love them so much. People are generally so inconsiderate with throwing down rubbish - all sorts not just glass, we need eyes everywhere. Hope all heals well with Penny x
