I just recently bought a Black lab puppy ( half English/ Half American). She is 12 weeks old. We got her when she was 9. She was perfect on walks, pottying everything. For the last 4 days she’s started to act all out of control. Nipping at me at all times! ( My pants, feet, hands everything. she’s great when we train her she sits, comes, lays down, leave it and the whole 9 with basic skills but she looses focus when outside. also she pulls the leash and bites it. please Help! Thank you!
Puppy biting is very common and can be so frustrating, but it passes! Check out the Labrador Site for great tips on managing puppy biting
Be pleased you have a compliant pup. The biting is the teething process, just as in babies. It'll pass.
