It sounds like you need to do some ore reading. Grab a copy of Dinbar’s book “Before and After Getting Your Puppy” and get some baseline knowledge about puppy care. The vet isn’t going to give you training advice (housebreaking, crate training, obedience). I’m a,os enjoying the podcast “Your New Puppy” By Debbie Cilento.
Our vet has us wait in the car, they take the puppy in, and then call to have the conversation after they examine him. This is our third dog, so it isn’t as jarring but it is still strange.
Puppies are a ton of work. Spend your time now reading and getting ready.
