We've touched on this before, but it's a good topic for all to be reminded on. The relationship with a client and vet is very important. Be open, be kind, be honest. Don't be a jerk. Don't try to guilt trip. They're doing the best they can for your pets, and you being a monster is going to only make the animal suffer. These vets are humans. Also, as they are humans, do remember there are established boundaries that must be kept. They may love your pet, your pleasant disposition, your behavior, and your business, but they may not necessarily want to be best friends with you. Nothing personal, just, it's their life and sometimes needs to be kept private.
