My 13 month old lab has come a long way to being a better behaved girl. She's been a land shark since the first day we brought her home at 8 weeks. The biting has almost completely fazed out. She can still be moody, and when she's having a tantrum she sometimes snaps and shows her teeth. It lands her in timeout and she quickly snaps out of the attitude. Tonight my husband was leaning beside her on the couch and she turned and snapped at his face. He moved back and she didn't touch him with her teeth. Both of us immediately said "No bite!" And told her "timeout" and now she's in the crate since it's technically bedtime. This is not a common habit, very rarely and more recent has it happened. Anyone else having dealt with this have any advice? This is not a habit I want to continue.
