We started our third puppy class tonight and it is so far superior to the previous two! The trainer "Linda" is excellent and gives me hope that we can ultimately control the dog! She not only clearly explains the methods but demonstrates them also. When I asked her how to prevent the dog from jumping and nipping my pants when I leave a room she told me that to prevent the bad action you teach an approved behavior. Like "sit" - "wait". This gal makes sense!!!!
