LOL.........nice puppy.
Seriously, nice little sucker! :lol:
OK, first get him a toy SO HE CAN BITE ON SOMETHING. TEACH him what is ok to bite and what is NOT ok. Simple solution.
So, when he bites your wife's sleeve, so NO immediately and put him in is crate. Stop all play. Then, about 2 minutes later, bring him out again. Give him a tug toy or any bite toy. When he goes for it, go nuts! Tell him how good he is. play tugs with him.
With a pup, there is no middle emotion. Either you are very unhappy (low low voice no physical punishment) and into his crate or BOZO the clown happy. Black and white.
This works with even the most BRUTAL pups. It all depends on YOUR consistency and persistance.
Remember. the tougher the dog..........the LESS physical punishement you must use. People often ask me why. They think the tougher the dog, the tougher the punishement to get into its head. LOL. I ask them.........." what happens if this dog is REALLY tough and it is 3 years old. Do you think it is going to take your so called punishment, then?" Real tough dogs will NOT and the aggression issues will grow. If the dog is really nice, he will not take the crap and take you to the hospital. :lol: This is why so many good dogs, in my opinion, end up in shelters with "aggression problems".
Tougher the dog the trainer must possess more brains, persistance, and consistency.. I don't say love here. I think you need more mutual respect. Respect for the dog (and even the pup). I think this is people's GREATEST mistake. They don't respect the dog/pup they are training. That also means you have to be the alpha. A great leader (pack leader - alpha) always respects and cares for his pack/subjects. Once we have that, we can try love.
Whenever people say, "the dog has to listen.....I am the ALPHA!!!!" I know that they do not understand this concept. Every great trainer I have worked with. They all had deep respect for the dogs they worked with. Now these trainers ask, "hmmmmm why should this dog listen to me. I have to find out. When I do, I can control him." Fundamental difference and a shift in thought. AND a much more FUN way to train!
