Took my dog to get yesterday today at Banfield. From what I have learned here sounds like ACE shouldn't be used. I questioned her on this and they said it was a myth and that there are no breed sensitivities to ACE. She stated it was standard for them to use a very small amount (.02 mg per pound) and they had never had any problems. Said they nuetered a boxer the other day w/out any problems. She said they won't use it if the dog has cardiac issues and/or history of siezures. Are there any vetrrinary sites that discuss this to show them? You would hope that they would be up on this kind of stuff.
