Am I Doing Something Wrong? My 1-Year-Old Poodle Is Out of Control

I’m looking for some advice because I have a one year old Miniature Poodle and I honestly feel like I’m struggling more now than when she was a puppy.

She chews absolutely everything, tears things apart, constantly tries to bite and nip me, barely listens when I call her, and barks so much more than she used to. It feels like all of her training has disappeared overnight.

What confuses me is that as a puppy she was actually much easier. She listened better, rarely chewed anything she wasn’t supposed to, hardly barked, and was generally very well behaved. Now it feels like she has become a completely different dog.

Is this normal for a one year old dog? Is she in her teenage phase? Has anyone else experienced this with a Poodle or another breed? I’d really appreciate any advice because I’m starting to wonder if I’m doing something wrong.
