and she is only eating a little chicken and only drinking really small amounts. I am not worrying too much about that but she is still weak and as she is lying next to me now she is panting all the time....has been for hours now. I am right to worry about this?
Another one to recommend ringing the vet. Panting/rapid breathing is usually a sign of distress/discomfort/pain. I'd be concerned about this. Did the vets give you any pain relief to give to her following the op?
My CKCS had problems after neutering, he started pantinhbreally heavily, I was worried so took him to emergency vets, vet said he was in serious pain and panting was his way of dealing with it. Vets he was neutered at put wrong size buster collar on and he licked sac, literally licked so much took top layer of skin off.
Emergency vet kept him in overnight with strong pain killers. Not trying to frighten you, but do take your dog to vets to be checked.
