Boxer Anxiety After New Puppy

A new puppy arriving can really knock an older dog's confidence — especially a Boxer who's had the run of the place for six years. The growling and hiding are him telling you he's overwhelmed, not being difficult. How long has the puppy been home, and are they being kept separate or is there a lot of forced togetherness right now?

Three weeks in and he's still hiding — that tells me his baseline stress hasn't come down at all yet. The puppy charging at him and not reading his signals is classic. Has he snapped or gone beyond the growling, or is he mostly just trying to get away?

The fact he's still choosing to walk away is actually a good sign — he's coping, just not coping well. The priority here is lowering his overall stress level so he has more headroom before he reaches his limit. I'd separate them more deliberately for now — the puppy needs to earn access, not just barrel in whenever. But alongside that, I'd recommend plugging in an Adaptil Calm Home Diffuser in the room your Boxer uses most as his retreat. It releases a synthetic version of the calming pheromone mother dogs produce, and it works quietly in the background to take the edge off without sedating him. It won't fix the dynamic on its own, but it genuinely reduces that ambient tension so he's not running on empty. One diffuser covers about 70 square metres and lasts a month.

It works for dogs of any age — the pheromone is naturally recognisable to all dogs, so it can take a little edge off the puppy too. Though honestly, with a boisterous pup, the bigger wins will come from managing their interactions and making sure your Boxer always has a puppy-free zone to decompress. The diffuser supports that, it doesn't replace it.

Most people notice a shift within a week or two, though some dogs respond faster. Give it a full month before judging it. If after a month he's still hiding constantly and the growling is getting more frequent rather than less, it's worth a conversation with a vet or a qualified behaviourist — sometimes there's an underlying anxiety that needs more targeted support. But for where you are right now, the diffuser is a solid first step.
