So i was taking my dog gunner on a walk this evening and since my fiancee thinks he is going to be a "hunting dog" he introduced him to birds ....Well come to find out he tries to eat them. So i hear that means they are not going to do good out on the field. So anywaz i was walking him and since he was introduced to birds everytime he see's one. He completly forgets that im on the other end of the 5ft leash.....Any tips to help me break this? also remember he is 114lbs so i cant just pull back
