We're clicker training our 12 week old puppy, and for the most part it's going well. The major problem we're having is that when we play with her she jumps and nips. Those little teeth are sharp and she's ripped jeans and shirts. My son was playing with her tonight and she really got him on the bare leg. I know it's playful, not aggressive, but I really want to nip this <ha ha> in the bud. She's only started doing this in the last week or so.
We are doing the standard-- turning our back (which is how she ruined my shirt) and ignoring her, leaning into her instead of stepping away, giving a sharp "eep" when she nips, having her sit, etc. Today I started using the clicker to mark four feet on the floor.
It's not working. If anything, it's escalating. Any tips?
