Wolfsoul you are still in the dark re aservice dog and a therapy dog.Go to Canines with a Cause. This is a program that is also in Ottawa, called CWAC. It might shed some light on what we are discussing. It describes the steps one has to take for obtaining a service dog. The matching, training, cost, certification etc
You might understand better what a service dog is. As for psd's they are not recognized in Canada unless assessed by a training team and the owner has medical references to uphold the need for one. Only a physician or psychiatrist is allowed to sign the necessary documents. As for the US I can't speak for their laws. But you will note in the CWAC that it states that an owner's pet dog is not used to train as a service dog. It also states that the dogs need at least basic obedience.
Nice to say, oh, my dog could do that real easy....but if you've never done it in the ring, then you really don't know if your dog has the courage to work under stressful conditions.
Did you bother to read Fred Lanting's sites? It doesn't sound like youdid or you would know what we are talking about when we say "GENETICS", and it's not old things from another era.
