Ya know I try and try with my Lab Otis. He is 4 years old now. But still seems to have so much puppy in him. He seems to listen really only when he wants to, or when food is envolved. And my biggest thing is keeping him in the bed of the truck. Any little things gets his attention and he is jumping out. How can I mellow him a little and not wanna run buck wild all the time. I fetch with him and walk him all the time, and he's still a mad man.
