I'm sure this has been discussed before, but this brings up a good topic. How do you pick a puppy? I'm pretty sure that our breeder will pick for us, but we have the option of "ranking" the puppy that we want when we visit for the puppy party. What exactly am I looking for? I have an older golden at home and two kids (ages 5 and 9). How do I know which puppy is right for us?
If your breeder is going to pick for you, I'd make sure your breeder knows what kind of dog you want to have in the long run or what kind of activities you are hoping to do with the dog.
I didn't have first pick and it didn't really matter to me, but I did let the breeder know I wanted a dog for competition obedience. The breeder steered me towards a particular litter for that reason and in the end I had a puppy who was very biddable and attentive and outgoing. Not that it mattered, because all of the puppies in that litter had those same traits.
I would guess if I had first pick, I'd sit down and pick a social, curious, and highly responsive puppy. With Jacks when I brought him home I could tap on the floor and he'd come running in to check out my hand. He was also the puppy who was happily greeting everyone at the breeders and trying to get everything into his mouth to carry around and play with.
The curiosity and responsive traits as well as his social nature made him ideal for obedience training as well as regular household and border training.
Our Danny was slightly different when we picked him - he was more independant and off on his own little puppy business. He wasn't so interested in other people as he was into checking out the visiting room we were in and playing with his littermate who was brought in with him. He was a great dog, but a little more difficult to train. He was more flighty.
