I just taught Smokey how to close cabinets and drawers. He is a German Shepherd/husky and is 14 1/2 years old. I want to teach him to open the frigde next. I think this might prove to be a little hard he does not really and hase never played with toys or been mouthy to grab anything with his mouth. I was wondering how I could teach him that. I can to him to play with me somtimes and grab on things, but he normally lets go after I pull a little, but sometimes he will hold on while I pull a little. Will it be impossible to teach him this? Where should I start?
