Puppy Boutique gets their puppies from puppy mills. Puppy mill puppies have very little human contact and are born to dogs who are poorly bred and not socialized as they spend their life in cages. These puppies often have behavioral problems, are difficult to socialize and sometimes impossible to housebreak.
I wish you'd done some research before purchasing a puppy from them. A simple Google search would have revealed all the complaints about Puppy Boutique:
