Wolf Q, great advice (master of devil dogs LOL). I too reccomend a puppy kindergarten and then follow w/ basic obedience. You to be boss here. Kong toys are great you can stuff them w/ all sorts op goodies, kibble, buiscuits, leftovers, peanut butter, cream cheese, yougurt etcc. they can even be frozen for a nice hot day treat & they last a little longer frozen. They will keep your dog occupied for a while and provide mental stimulation.
