Hi all,

My Beauceron is 15 months old and had her first heat back in May. For a while afterward she actually calmed down noticeably — but in the past few weeks she’s done a complete U-turn and started acting like a young puppy again, and honestly it’s worse than her puppy phase ever was.

Here’s what’s changed:

**•	Mouthiness**: She’s mouthy pretty much constantly throughout the day now, way beyond what she was like as a young pup.  
**•	Humping**: This has come back out of nowhere — she hasn’t done it since she was little.  
**•	Panting**: She pants a lot, like she’s stressed, even when she hasn’t been active. She often is a panty dog but this is excessive and she appears very stressed  
**•	Whining/whimpering**: Frequent, including while she’s playing with toys, which is new. She often does it just walking around the garden or house  
**•	Destructive chewing**: She’s started destroying things (sofa, her bed) — she never did this even as a young puppy.  
**•	Listening/commands**: She’s noticeably less responsive to commands she previously knew well.

Things we’ve ruled out or tried:

**•**	Took her to an **orthopaedic vet** — nothing found.  
**•**	Started a **pain medication trial** yesterday on the vet’s advice — no improvement yet, but it’s early days.  
**•**	Feeding is correct type/amount for her age and size.  
**•**	Exercise seems appropriate — not over- or under-walked.  
**•**	Thought it might be overstimulation, so tried a few days of shorter, calmer walks — made no difference.

Has anyone experienced something similar, especially post-first-heat? Could this be hormonal, behavioral, or something else we should be looking into? Any advice on where to go from here (further vet workup, behaviorist, etc.) would be really appreciated.

Thanks in advance!
