My wife and I just bought a yellow lab from a pet store, he was 12 weeks old when i brought him home. All we want is to be able to love him up and for him to love us back. We do everything to show him that we love him, but he just does not want to please us or obey us. He seems to demand what he wants, like when he wants his belly rubbed, he will come over and lay on his back expecting a belly rub, if we don't do it right away he starts to bite untill we give in and rub his belly. Or even when my wife is just watching TV, he simply comes over and lunges at her and starts biting, growling and barking. It has gotten so bad that we cannot eat anything in front of him, because he starts to bark, growl and then he jumps up on us and tries to forcibly take the food from our hands constantly biting us in the process. He does not fear me or my wife and we just don't know how to control his aggressiveness. We took him to an obedience training class and the trainer taught him sit, come, and to "take" food from our hand gently. The only problem with the training is that he only listens when he knows we have a treat in our hand, otherwise he acts like he doesn't understand what we are telling him. We approached the trainer about his biting, and it was suggested that we distract him and give him something else to bite on and then praise him. It only worked the first day, and now he takes the nylabone, chews on it for a few seconds and then drops it and comes right back at us. We have tried advice from the Vet to no avail, and we are looking into another trainer and read up on several books, but nothing is helping. PLEASE any advice would be appreciated.
