You should find a trainer through your vet's, most advertise at least 1 or 2.

As for the training, you'll find it's more about training the owner in how to train the dog. A lot of it seems like a waste of time, but it's good practice for when you need to actually teach it someting useful.

We took our pup and put her through the keenel club puppy foundation, then bronze, then silver programmes. 2 years on and she probably still remembers it all. It's said the first 18 months are the most important in a dog's life for learning things

Good luck!!
