Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place." 
On the other hand, praising a puppy for doing the right thing works best for everything you will do in your life together. Make her think that she is a little canine Einstein every time she performs this simple, natural act. Be effusive in your praise—cheer, clap, throw cookies. Let her know that no other accomplishment, ever—not going to the moon, not splitting the atom, not inventing coffee—has been as important as this pee.
Dogs don’t speak English, and just because we might yell at our dog as we catch him in the middle of peeing on the floor and then rush him outside where he finishes it off… doesn’t mean we did an effective job at telling him that outside was where he was supposed to go. We are usually too focused on getting him NOT to go inside, instead of going outside.
In considering the natural behaviours of specific breeds of dogs, it is possible to train them to perform specialised, highly useful, tasks. For example, Labrador retrievers are the favoured breed for the detection of explosives. This is because of a combination of factors including their food drive which enables them to keep focused on a task despite noise and other distractions. Most working breeds of dogs are able to be trained to find people with their sense of smell (as opposed to their sense of sight). Cocker Spaniels are able to be trained as part of a termite detection team. Their relatively small size enables them to fit into small spaces, and their light weight allows them to walk on areas of ceiling which would be dangerous to anything heavier. In fact, although unusual, termite detection dogs are much more reliable at detecting termites than humans who rely on a basic system of tapping and listening. Because of their ability to learn signals by sight and for their energetic and athletic natures, German Shepherds are able to be trained for work alongside search and rescue teams and human apprehension teams.
