This is a specific conversation about Dog hiking gear — what you actually need — ask about yours and get one honest answer for your exact situation.

A Chow Chow that overheats on summer hill hikes — that's a genuinely important thing to get right, because that dense double coat is basically a thermal trap and heat stress in Chows can escalate faster than people expect. The essentials for hiking with any dog are a well-fitting harness, a collapsible water bowl, and paw protection for rough or hot terrain. But for your dog, there's a fourth essential: active cooling. Before I point you in a specific direction, can you tell me roughly how long your typical hikes are, what kind of gradient you're dealing with, and whether you're usually starting early or hiking through the midday heat?
Usually 2 to 3 hours, moderate hills, and yeah we often end up hiking late morning into early afternoon which is probably the worst time for him. He's a big boy, about 28kg.

Right, that combination — late morning start, moderate sustained incline, 28kg Chow — is genuinely high risk in summer. The problem isn't just air temperature, it's that Chows can't shed heat efficiently through their coat, and uphill effort generates a lot of internal heat fast. How obvious are the signs you're seeing? Are we talking panting heavily and slowing down, or have there been moments where you've had to cut the hike short?
He slows right down after about 45 minutes and pants really heavily. We've cut a couple of hikes short. I've been soaking him with water but it doesn't seem to do that much.

Pouring water over the coat is the instinct but it's actually not very effective on a Chow — the outer coat repels water and the undercoat insulates, so it doesn't reach the skin where it matters. What you need is a proper evaporative cooling vest that sits against the body and uses directed evaporation to pull heat away. My recommendation for a dog his size is the Ruffwear Jet Stream Cooling Vest. It's designed specifically for working dogs in heat, it has an evaporative lining that you soak and wring out before putting it on, and unlike a lot of cheaper vests it's cut to allow airflow rather than trap it. It's available in a size that'll fit a 28kg Chow and it's held up well in real trail use. Pair it with a Ruffwear Front Range harness worn over the top, and a 500ml Dexas Popware collapsible bowl so you're offering water every 20 minutes — not just when he asks. That combination will make a real difference.
That makes sense about the water just sitting in the coat. Does the cooling vest work even when he's moving and panting a lot?
inparticular.ai
Yes — actually movement helps it. The evaporative cooling effect increases with airflow, so the faster he's moving, the more heat it draws away. The key is re-wetting it when it dries out, which in summer heat on an uphill hike might be every 45 minutes to an hour. Carry a small extra water bottle just for the vest if you can. One more thing worth saying: even with the vest, a Chow in summer should ideally be on the trail before 9am or after 5pm. The vest buys you more time and safety margin, but it doesn't override the physics of a black-tongued dog in direct sun at noon.
Really useful, thank you. I'll look at the Ruffwear vest. Should I also be thinking about boots for him?
inparticular.ai
For a Chow on moderate hill terrain, boots aren't the priority — their paws are generally robust. The one exception would be if you're ever hiking on compacted gravel paths in full sun, where ground temperature can be 20 degrees hotter than air temperature. If that applies, Ruffwear Grip Trex boots are the most reliable option in the UK market, but I'd focus on the cooling vest first. That's the thing that's going to change his summer hikes meaningfully.
