We just get a new 11 weeks old Rottweiler. I am not a dog person, and I don 't know too much about the training. Any tip would help. One specific question I have is: He likes to lick his hands, and once and a while, rubbing his teeth into them. A little pinch of love I guess. Should I stop it entirely, or do I train to keep it nice and not bite hard? Im thinking if he keeps it nice, so get used to having hands in his mouth when we need to remove the rocks that he chews on and brush your teeth. ¿Council?
