OMG! I would be sooo upset, but I imagine you are! Could it be that she has a strong reaction to any antibiotic? Just curious because it seems odd that she can't tolerate Amoxicillin and then this happens with Baytril.

The good news is she can still see shapes, so she's not totally blind, and she may just surprise everyone and get at least partial vision back. Although, like others have mentioned, there are many similarly "handicapped" pets out there that function just fine, and I'm sure she'll adapt and be just fine herself.

It is too bad though, and I would definitely let everyone involved (vet, Bayer, etc) know exactly how I felt about the situation.

I remember Tubby was given Baytril - and possibly Peanut too - when they had UTIs, and never once did the vet mention there was a chance of blindness! With humans, you always get the instructions from the pharmacy with the list of possible side effects - we don't get that from the vet. It's like we're at their mercy to tell us everything unless we do our own research online - and who's going to do that when your baby is in pain and can't pee? It's just a sad sad situation.
