T.P.
I appreciate wanting a specific puppy, but have you considered a rescue? You can probably find the breed you're looking for while saving a dog's life.
"Don't breed or buy, while shelter animals die."
Also, puppies have lots of little 'bad' behaviors that they will grow out of ... young adult rescue dogs have outgrown these, are still very trainable, and usually very grateful.
Most rescue organizations charge a $50-$100 adoption fee.
