I have a question, for Brooke's spay on Wednesday I asked the vet what type of anesthesia she will be using and she said they use ketamine and valium for induction of the tube and then isoflorane during the procedure. I know iso is the prefered type but what about the ketamine and valium? Are they okay? They had an alternative called propofol for an extra charge which I'd obviously pay if it is preferred for bulldogs. thanks in advance for any advice/ experience
