I'm with Jag on this one. You have a whole lot of dog on your hands and he's not getting what he needs from you and your family to reach his potential. He needs boundaries and training and he's not getting them. He needs exercise, mentally and physically and he's not getting it. You have a dog that needs structure and it sounds like things are pretty scattered right now. This is a dog that should have been getting training even just in obedience from a young age because now you have a large puppy who will use his size to let you know he doesnt agree with things. He jumps and bites and humps on you because he's never been corrected or taught otherwise.

These dogs get so excited to be with their people that when you come out in the yard with him, that excitement boils over. He doesnt know how to control it. He needs help to learn. left to his own devices, you'll have an unruly dog and no control. This leads to the animal becoming a liability. The number one reason animals are ditched in shelters is due to behavior problems.

Either step up hard now and work with him or find someone who will take on the challenge he's become and help him get where he should be to be amazing.
