Believe me, when he first tried humping me, I was concerned, I went straight to another dog training forum I belong to and a member there gave me the groundwork link. I found it very helpful and have listened to it several times since then.
The first time I took Ty to my vet, the vet said that I would have issues with Tys very dominant behaviour, the vet was very concerned (this was on the third day since we got him).
We went back to the vet 2 weeks later, after implementing the plan in the groundwork podcast and the vet was truly gobsmacked at the change in Tys behaviour and posturing towards the vet. He was full of praise and said that he could not believe we had reshaped him so quickly. He said he had in the past only ever seen one other dog at the same age with similar dominance issues and for him to be behaving like a normal puppy two weeks later was nothing short of amazing. So thanf to Ed for saving us.

There has been no humping for 2 weeks now, he had stopped it after only 1 week but after playing with a dog at puppy preschool who kept humping him, he decided to try it on us again, but that lasted only a few minutes and there has been no re-attempt. He is a hard dog but seems to know his rank is below ours now and I think that has gone a long way towards making him happier, he knows we will protect him and he doesn't need to try and leed.
He was handraised, as were the rest of his litter and he was the head of the litter, so it took some adjustment but he is doing great. Thanks for the link. If I wasn't already aware of it, you could have saved us, just in time.

We are definitely aware of the importance of taching the groundwork. I haven't seen any dominant attitude in him for weeks. We make him sit before each doorway and he is only allowed through after we pass. He knows this already and is doing well with it.
He has to sit before he gets petted. he sits before food. He is just now learning drop. He is on leash almost every minute he is not in the crate. The only problem I have with this is that trying to be such a taskmaster all the time leaves little room for loving him. I have to say that in the last few days, I have fallen totally in love with the personality he is revealing though.
On the way home from work (he comes to work eachday with me) he is harnessed in but can just reach my arm while I drive. He has started leaning his head against me all the way home with the occassional lick thrown in. He is actually very very sweet whe he hands over the reins and lets us be boss. We will continue with the groundwork by the book for months to come and see how we go.

Nikki, Sounds like you're on the right track....getting through puppyhood can be very trying. Look at it this way, it doesn't take as long for dogs to grow up as it does kids. For right now you're just gonna have to be the task-master. It will be worth it in the end! Hang in there.....

Well, he is doing terrifically. He has been with us for a month now and is no longer growling over any of his posessions, including food. The only time we here a growl out of him is during play, he growls when he gets right into tug of war, he also gets a bit possesive over the soccer ball when we are playing with it, but if it gets over the top we end the game.

Ty seems to be very happy with the structure and routine in his life and would make an excellent poster child for crate training, he never whines or carries on when he is sent to his crate. Now that we have figured out the level of activity he needs to be comfortably tired, he is rarely getting into trouble. I think he is going to be terrific dog, love him to death!
