My dog is 5 months old. He is full of energy, VERY FRIENDLY, always wants to go out for a walk, always super hungy. He refuses to sleep. We have to leash him to his bed, he would bark,cry for 30mins before falling asleep. He is also always hungry, would pick on litter when I take him out on a walk and growls if I ask him to leave it. Idk what I am doing wrong or where am I not training him. Please help
