Can dogs go in hot tubs?

The heat is the real danger. Hot tubs run at 37–40°C. Dogs can't sweat to shed heat the way we do — they rely on panting — so hot water pushes them towards overheating and heatstroke remarkably fast, in minutes rather than the half-hour you might happily soak for. That alone makes it a no.

The chemistry doesn't suit them either. The chlorine or bromine that keeps the water safe for people is an irritant to a dog's skin, eyes and stomach — and dogs make it worse by licking it off their coats afterwards. So even a cooler tub isn't a dog-safe one.

And it wrecks the tub. Dog hair, oils and dander clog the filtration and knock the water balance out, which is costly to fix and leaves the tub out of action for the next guests. That's why the ban is universal across holiday-lodge stock — it's etiquette and hygiene as much as safety.

It means the dog is welcome everywhere that matters — the lodge, the garden, and nearly always the decking around the tub — just not in the water. You get your soak; the dog stretches out on the boards beside you or dozes by the wood burner. That's the normal shape of a hot-tub holiday with a dog, and it works beautifully.

The thing to check when you book isn't whether the dog can swim in the tub (it can't, anywhere) but whether the outdoor space is enclosed, so the dog can be loose near the tub rather than held on a lead. That's exactly the detail we surface on our dog-friendly hot tub lodges guide — verified private tubs with dog policies that stand up, by region.

If your dog loves water, pack a cheap paddling pool for the garden in summer — a far better idea than the tub, and most dogs prefer it anyway.
