Cooling vests for Labrador and Golden Retriever

You've got two big, heavy-coated dogs — a Labrador and a Golden Retriever — which puts both of them in a higher-risk category when temperatures climb. Heatstroke is a genuine danger for dogs like yours, and cooling vests work through evaporative cooling, so you wet them down before use and they're most effective in drier heat rather than humid conditions. To point you toward the right sizes and style, I need a bit more detail: what breeds specifically are they — standard Lab and standard Golden, or are either on the larger or smaller end? What situation are you cooling them for — garden, walks, car trips? And how active are they when it's hot?

That's a useful picture. South of England summers are actually good conditions for evaporative vests — warm enough to need them, dry enough for them to work well. Your Lab at 32kg is solidly in the Large territory for most vest brands, and your Golden at 27kg will likely sit at Medium to Large depending on chest girth. The key thing with Goldens is their chest can be broader than their weight suggests, so you'll want to measure chest circumference before ordering. What's the chest girth on each of them if you know it, or have you measured them before?

It matters quite a bit — a vest that's too loose won't make good contact with the coat and loses most of its cooling effect. A barrel-chested Lab can easily need an XL even at 32kg if the chest measurement is over 90cm. Go ahead and measure both dogs around the widest part of the chest, just behind the front legs. I'll wait — it'll save you a return.

Perfect — that's exactly what you needed to check. For both dogs, I'd recommend the Ruffwear Swamp Cooler Vest. It's the most reliable evaporative vest on the UK market, genuinely well-made, and it comes in multiple sizes with clear chest measurements. At 91cm, your Lab goes into XL, and your Golden at 82cm sits in Large. They're different sizes, which is actually straightforward with this vest since you just order two separate sizes. You soak it in cold water, wring it out so it's damp not dripping, and it keeps cooling for 1–2 hours on a morning walk. For active dogs in dry heat, it genuinely works. Search 'Ruffwear Swamp Cooler' on Amazon UK — it's available in both sizes and they ship quickly. One thing: measure again once yours arrive, as the sizing chart on the product page uses chest girth and confirms what I've told you.

A few practical things: keep a small water bottle on your walk to re-wet the vests if they dry out — in warm weather they can lose their cooling effect after 60–90 minutes of activity. Never leave the vests on in a car or enclosed space; they're for active use in airflow. And watch both dogs for panting that doesn't ease off, drooling, or stumbling — those are early heatstroke signs and mean you stop, find shade, and pour cool (not ice cold) water over their paws and neck. The vests reduce risk, they don't eliminate it. Morning walks before 9am are still your best protection alongside the vests.
