Hey guys. I have a 3yr. old Cocker Spaniel. Actually she was my wife's dog before we were married. I would like to train her basic commands first, such as "sit," "come," stay" and "whoa". I would also like to eventually train her to retrieve. I had a Chessie that I trained myself. She turned out to be a pretty good bird dog, so I am not a total greenie. However, I started training my Chessie at 10-12 weeks old. Sophie is 3 years old. I never bothered training her before, because my wife had not trained her before we were married. She will not come when called unless she wants to. I am pretty certain that she understands this command. I think she is just being stubborn. Any ideas? Is it true that you can't teach an old dog new tricks?
