Quote:
If any punishing is to be done, seek out the breeder, the puppy mill, the pet shop, or the overzealous trainer who failed to give your dog the socialization it needed to develop into a confident individual who trusts that the world is a benevolent place, and punish them. Even just weaning puppies too early and separating them from their mother deprives them of essential development time. Sometimes, however, the mothers, raised in puppy mills, have become lifetime submissive urinators themselves, and have passed this lesson on to her offspring.
