My 4 year old frenchie was panting so bad this summer I got really worried about him. Ever since I put this on him for walks he's doing so much better. Honestly so relieved I found this.💗

Chloe M, Verified Buyer

I live in Florida and every single summer I dread taking my dog out because he overheats so fast it's scary. My vet actually told me to look into cooling vests and I ended up finding this one. I've been using it for about three weeks now and the difference is night and day. He used to start panting heavily after like five minutes outside and now we're doing 20 minute walks no problem. I tell every dog mom I know about this thing.

Bought this for my dog after he had a pretty bad overheating episode last July that honestly scared the hell out of me. Vet said we needed to be way more careful in the heat so I started looking for something practical. This harness is dead simple to use and it actually works. You can feel the fabric staying cool even when it's 90 degrees out. My dog tolerates it really well too which I wasn't expecting because he hates wearing anything. Solid product.

My dog has always struggled in the heat but this past summer was just brutal and I was genuinely nervous every time we went outside. She would start panting within minutes and I was constantly cutting walks short. A friend recommended this vest and I honestly didn't expect much but wow. She stays so much calmer on walks now and the panting has reduced so much. It's easy to put on, fits her well and the quality feels really good for the price. I already ordered a second one to keep as a backup.

Ordered this for my frenchie and honestly the quality surprised me. The fabric feels really sturdy and well made, nothing cheap about it. It fits him great and stays in place during walks which I was worried about. The velcro and the clips feel solid and the material itself feels really cooling even just touching it with your hands. Very happy with this purchase.
