I have trained dogs using the water dog books and have always had meat dogs that got that got my birds and brought them back and sat and waited for the next one down.Im guilty of not training them to their potential . I did all my due diligence/research on the breeder and despite that she came with mange which was terrible and affected her concentration and training and perhaps her attitude.She is not stupid but very strong willed and pig headed....That asside, i have been working on basic obedience like sit/stay and off and making here wait till we say ok to eat and leave it as well as fetching bumpers in the garage and outside when weather permits. She has come along way health wise from the condition we got her in and we really like her. I messed up not using a check cord to bring the paint rollers and dummies all the way back and now she wants to play keep away and when she does come back to me on the check cord she does not want to let the roller or bumper go and has a really firm grip on it. What would you guys suggest. She is 6 months now and i have the hilman puppy dvd but we are not even to the point where he is with a much younger pup.She wants to either hold onto the dummy or not bring it back. I have shortened her training to ony a half dozen throws twice a day and continue to work on her manners around the house and her pulling on the lead.We switched to an ez-lead and she still want to pull on that or chew on the leash and shake it violantly. My previous 3 dogs ahd totally different dispositions.This one is a wild child and wants to be dominant.She was the only black female in her litter and the smallest .We love on here all the time .
