So I have a husky cross a rescue from the organization I was working with. Got him at 8 weeks and he was born in care so no bad history or anything. He is 13 weeks old now and has learned very well, he is house trained sits and stays patiently waiting for his food (I make it so it can take a little while). Doesn't jump on anyone but our roomie who refuses to assert himself with the dog. He has learned not to jump on my son but I do find and I think it's because of the lack of respect for the roommate he will test other people who come into the house. Jump on them try pulling at their clothing etc.
We have done walks/runs twice a day for some time and he has picked up the following commands, heal, sit, stay, whoa, easy (walk in front), hike (run in front) I am hoping to do some canicross and skiijoring with him next year. Here's the bad part 2 days ago while we were running so in "Hike mode" he turned and started biting at the leash I tried to correct him on the move but he turned and started jumping and nipping at me almost knocking us both over. I disciplined corrected and continued on and he tried it again a little while later again I corrected disciplined and moved on. But yesterday the same thing he started jumping and nipping when I was making him heal. It seems to be when I'm not letting him run when he wants to or as fast as he wants to. Yesterday I was making him sit while he was doing this and he nipped. I'm not pulling away when he's nipping but I ended up putting him into submissive position yesterday and he actually drew blood on my hand not badly and I didn't pull away I held out and in the end he laid down what I thought was calm for several minutes before I gave him the command to come up and almost instantly he started jumping and nipping. Still no change in the house. He listens to me completely but I seem to loose control outside the door. Any ideas?
