Take a deep breath!
Find quality breeders and ask them to help you pick a puppy.
Pups may differ in the same litter, but a hands on breeder will know.. Also good breeders are often very helpful in finding a pup if they don't or won't have what you're looking for.
Just know that any pup will tax you while young. These well behaved dogs weren't born that way. Just like each of your children needs training, so will a puppy.
