This is a specific conversation about Dog cooling vests — keeping them safe in heat — ask about yours and get one honest answer for your exact situation.

A young Golden Retriever living the campervan life sounds brilliant — but that thick double coat makes heatstroke a genuine risk, especially when you're moving through different climates and can't always predict what conditions you'll hit. Cooling vests work through evaporative cooling: you wet them, and as the water evaporates it draws heat away from the dog. They work best in drier heat — in high humidity they're less effective, so it's worth knowing that going in. To point you to the right one: what climates are you mostly travelling through right now — dry and sunny, or does it get humid too? And is your Golden getting proper off-lead exercise in the heat, or are you mostly managing walks and rest stops?
We're currently doing southern France and heading into Spain — it's been hot and dry mostly, mid-30s. She gets a long morning walk before it gets too hot but we do stop at places where she runs around. She's pretty energetic for a one-year-old.

Mid-30s and dry is actually the sweet spot where evaporative cooling vests perform best, so you're in good territory for this. With a one-year-old Golden who's active and stopping at different places — rather than doing structured trail runs — you need something robust, easy to re-wet on the go, and adjustable enough to fit well even as she fills out a bit more. What size is she roughly — do you know her weight or chest measurement?
She's about 27kg, I'd say medium to large. We haven't measured her chest but she's on the bigger side for a female Golden.

At 27kg she'll sit in a large on most vest sizing. For your exact situation — dry heat, active dog, campervan travel where simplicity matters — I'd go with the Ruffwear Swamp Cooler. It's a proper evaporative vest with a reflective outer layer that blocks radiant heat on top of the cooling effect, which matters when she's sitting in sun at a stop. It's genuinely durable, stays wet for a decent stretch, and the design holds up to being shoved in a bag and re-wetted repeatedly, which is exactly how you'll be using it. The large should fit her well — measure her chest just behind the front legs if you can, as Ruffwear's large runs roughly 81–97cm. It's not cheap, but it's the one vest that genuinely handles daily use in serious heat rather than being a one-trip novelty.
That sounds exactly right. How long does it stay cool once you've wetted it?

In dry heat like southern Spain you're typically looking at 30–45 minutes of active cooling before it needs refreshing. In shade and lower temperatures it'll last longer. The practical approach with campervanning is to wet it before a stop where she'll be running around, and keep a small water bottle in your day bag specifically for topping it up — just pour a bit over the vest rather than full re-soaking every time. On a hot rest stop day, wetting every 45 minutes is a reasonable rhythm. Also worth knowing: wet the vest, not just the outside — squeeze water through so the inner layer is damp against her skin, that's where the cooling actually happens.
Really helpful, thank you. We'll go with the Ruffwear Swamp Cooler in large.

Good call. One last thing worth knowing: the vest helps but it doesn't replace the basics — shade, fresh water, and not pushing her during peak heat between about 11am and 4pm in that southern European sun. At one year old she's still got some puppy enthusiasm that outpaces her heat tolerance, so she won't always self-regulate. The vest gives you a genuine safety margin, but you're still the one keeping an eye on her. Have a great trip.
