Max is 4 months old. We've been going to puppy classes at Petsmart which she enjoys. She
gets along with the other dogs, who are 3 times her size. She's doing good with all her "homework" except the loose leash walking. I've tried everything to get her to take just a couple steps with me. When the leash goes on she is ready to take off. I've tried stopping until she comes back to me but she just lays down. Treats only work for a few seconds than she lays down again. Max wears a harness when we try to go for a walk and she is never lifted by it. Sometimes I think my arm is going to fall off with the way Max pulls. Any advice would be greatly appreciated...............
