I just got a new anatolian/pyranees cross puppy. He is 16 weeks. I dont think he had ever been out of the pen. He was calm and loving and came right up to me so I chose him out of 13 puppies. He did great on the ride home. However, he did not want to get out of the car so my hubby lifted him out and he got off his leash and took off we caught him and he just seems terrified. I left him alone last night. This morning he came up to me but was still scared. I just dont know how to make him feel safe. I need a companion for out in the country. He is very afraid of the leash and collar. I might add he is a very big boy. I would say about 50 lbs already. I just dont know where to start with him. I have to be able to aproach him and he does have to have a leash for travel from field to field any advice?
