Sometimes its a judgement call on the type of meds to give and also pennicillian is for infection of some types and not others. Bio and LA cover infections also and its not only respritory infection either. Yes get her up and if the vet will give it to you get some Dex in her for the swelling and some banamine for pain. I keep both here...never know when you will need it. get her moving as fast as possible and some water also. the more she moves the better she will get.
