Hines is now 5 months old and I try to take him on long walks every day. For the past couple of weeks every time I take him out it seems we get maybe 5 steps into the walk and he starts attacking me, jumping on me and biting me uncontrollably. I get him to sit and calm him down and then start walking again and he is usually fine for the next 5 minutes or so and then it starts again. It is becoming impossible to walk him as every step I take he jumps on me and tries to bite me. I think it is because he does not like to walk because it is always when we first start the walk and then again when we are about 5 or 10 minutes in. Once we turn around and head back towards home he is perfect and walks next to me the whole way home. Any suggestions?
