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 brief collapse in the heat is a serious warning — your vet is right to flag this, and the fact it's already happened once means your Chow Chow is at real risk if it happens again. Chow Chows are a double-coated breed with a naturally narrow airway, which makes them significantly more vulnerable to heatstroke than most dogs. Cooling vests work through evaporative cooling — you wet them, and as the water evaporates it draws heat away from the body. They're most effective in drier heat and need re-wetting every 20–40 minutes in direct sun. Before I point you to the right vest, can you tell me: what's your typical situation — garden, walks, car trips? And does he still go out much in warm weather, or are you mostly trying to keep him safe during unavoidable exposure?
He's 9 and pretty slow these days, we don't do long walks. But last summer he collapsed in the garden during a heatwave — just lying in the sun too long. The vet said to get a cooling vest and limit his sun exposure. We're in the south of England so we get warm dry spells in summer. I want something I can put on him if he's out in the garden or if we do a short walk.

That context is really helpful. Given that he's older, already had a heat incident, and you're dealing with dry summer heat in southern England — evaporative cooling will work well for you. The south of England's summer heat is typically low-humidity enough that these vests perform properly. For a senior Chow Chow in this situation, I'd recommend the Ruffwear Swamp Cooler. It's a proper evaporative cooling vest — not just a reflective layer — and it's been the benchmark product for working and at-risk dogs for years. You soak it, wring it out, and it keeps cooling for 20–40 minutes depending on conditions. It covers the back, sides, and chest well, which matters for a thick-coated dog like a Chow. Chow Chows are typically a large to XL in Ruffwear sizing — I'd measure his girth behind the front legs and check their size chart, as fit matters for coverage. The main thing: don't wait until he's panting heavily to put it on. Wet it and get it on him before he goes out in the sun.
That sounds right. Should I be doing anything else alongside the vest, or is that enough on its own?

The vest is a tool, not a safety net on its own — especially given his history. A few things genuinely matter alongside it: keep fresh water available at all times and encourage him to drink before going out, not just after. Avoid the garden between roughly 11am and 3pm on hot days — even with the vest on. If you notice heavy panting, glazed eyes, wobbling, or refusal to move, bring him inside immediately and wet his paws and groin with cool (not cold) water while you call your vet. At 9 years old, his ability to regulate temperature is slower than it was. The vest buys you time and reduces risk — it doesn't eliminate it. Combined with shade, water, and sensible timing, you're giving him a solid protective routine.
Really useful, thank you. I'll go with the Ruffwear Swamp Cooler and make sure I'm not relying on it alone.

That's the right approach. Get his measurements before ordering — Chow Chows can vary quite a bit and a well-fitted vest makes a real difference to coverage. You're doing the right thing taking this seriously after last summer. With the vest, sensible timing, and shade, he should have a much safer summer.
