I can't imagine now having to pay a vet bill and WAIT for an Rx to arrive after getting a prescription, for something we've already been treating our cattle for. We keep certain antibiotics in the fridge, insurance against future problems.
Meanwhile I've had to argue a couple times with dog/cat vets over why they're jumping straight to antibiotics for extremely small problems. One time I was quite casually given a human-relevant antibiotics that I'm allergic to with no mention of what it was (definitely my bad for not scrutinizing the label until I got home, but I was just handed it like it was a nutritional supplement or something!).
