I have a series of vetting macros in a hotbar, no keybindings on them. Each one bandages a particular pet as a stored target. I have two vacant slots in the hotbar next to these tiles, with the keybindings F5 and F6. Whenever I pull pets from the stables for hunting, I drop the corresponding macro tiles into the vacant slots. In this way I've assigned vetting pets to those two keys without mucking about with clearing & resetting keybindings. I know this approach won't be news to some of you but as soon as it occurred to me it seemed like such an epiphany, I had to share it. I have named all the macros "Vet - PetName" and so forth to tell them apart as I only have the standard icon set at the moment. What I do is use tiles that look like the pet.. Animal Form for dragon & wyrm, Talon Strike for raptors, Vet for cu sidhe (dog + heal symbol), Poison for rune beetle, etc. I should look into getting custom icons, though..
