I got my puppy, Rudy, about a month ago. He's a lab-bulldog mix and is about 10 weeks old. When I take him on walks, he acts like he doesn't want to go out of the door. Rudy whines and tries to pull away, then he just gives a grunt and trots outside. When we start to go down the street, he keeps pulling back and whining, wanting to turn back, then Rudy finds a pinecone and picks it up. I try to grab it from him saying "Drop it!" but he tries to pull away from me. When it seems like he finally starts to walk with me, he chases after my legs, and tries to mount them, and bites my pants. Rudy's made me bleed through the skin many times, so now my legs are covered in puppy bites and he's ruined a good pair of pants. I try to just keep walking, but when he bites, he won't let go. If I try to pick Rudy up, he'll bite my shirt or hand and I can't take it out of his mouth because his grip is so tight. He's great to play with, but awful on a walk. Anyone have any ideas?
