Long story short I adopted a two year old malamute. I know his history he was spoiled and not made to behave by his first owner. When his first owner was forced to give him up for adoption some punk got him for a intimidation dog, (I.E meth lab gaurd dog) as he is 140lbs and about 6 foot standing on his hind legs. Anyway that POS owner didn't have him very long before he lost him to the courts. I adopted him and he is wonderfull but he has some issues that I hope to be able to train out of him. First he loves to smack things with his paws. He reaches up like he is going to shake and then WHAM you punches you! He seems to be trying to get you to play but as you can imagine from time to time this hurts quite abit. He is also very hyper and trys to PLAY all the time. I am 6'3 250lbs so we can play hard but he thinks he can pay like that with everyone. His basic commands coud use some work Sit,Down,Come,ETC. My quesiton is at two years old and on his third owner what steps do I need to take to train him? I love this dog and I belive that he can be trained but I to make sure that I do it properly. Thank you in advance for any and all advice.
