Thanks to all your excellent advice, we have come to a decision that (a) we are getting a puppy and (b) we have found a breeder.
As things stand, our new little baby substitute puppy is not even a twinkle in his/her daddy's eye yet but we expect to have one some time in the spring. So... what do we do now?
So far I have: bought and read a book on pre-vaccinated puppies. Identified a local vet and a couple of possible puppy training classes. Met some people who own these sort of dogs and got some advice on feeding, etc. What else should I be doing/buying? Should I be registering for classes (and vets) in advance?
I keep reading threads about people who want to get rid of their dogs and I am determined that I'm not going to be that person so all advice for preparing myself and the rest of the family would be very gratefully received (again).
