this topic, no doubt, has been discussed over and over, but as a first time dog owner, i have tried everything suggested to control the jumping. the other day someone came in to check the furnace and i put my dog on a leash but he was very disobedient, kept biteing the leash etc. maybe i should have put him in a room by himself while the man was there. i am at a loss as to what to do. benji is almost 2 years old. i would appreciate any replys.
