Sounds like the bratty stage to me. It used to drive me absolutely NUTS when Rookie would do that. In his case, he would usually grab the leash first and if I tried to stop him from grabbing the leash, he'd start trying to grab my hands, my arm, etc. The only thing that worked was a tip I got from someone here on the forum. I carried a small spray bottle in my pocket with a mixture of water and bitter apple. If he started to grab the leash, I would squirt the mixture of bitter apple on the leash. Rookie hated bitter apple, so it would stop him immediately. After spraying only a few times, all I had to do was take the bottle out of my pocket and he would stop immediately.
Hang in there! It really is just a stage and you'll get through it.
