I know who, but I believe he is retired. I think he might know someone.
Basically, training a dog requires three things:
1) Be consistant
2) Be firm
3) Did I say "be consistant"?
Okay, I checked with the guy I know and this was the result;
1) Praise--which is "Good boy/girl! Atta girl!"and so forth when they do something right
2) Correct them: "No" when they do something wrong. They don't speak but they understand tones and gestures.
3) Be Consistent!!!! Praise the same things and correct the same things. They learn quick.
You do not have to hit the dog, in fact it is a no-no.
As soon as I make contact with this individual, I will see what is available.
