Our 9 week old basenji loves to chew. For the most part, we've got this under control (by watching him carefully and replacing stuff he can't chew with stuff he can). Where we don't have this under control is when is comes to chewing us: every time he gets excited (ie play time) he starts nipping at us. He's not being aggressive, but it's still behaviour we'd like to "nip" in the bud. Lots of people seem to have had success with ignoring their dog for a little bit whenever he nips, so we'd like to try that, but we're unclear on a couple of points. First, how long do we ignore him for? And second, often he'll miss when he nips, sort of like snapping but much slower. Should we ignore him for this or wait until he actually connects?
