Kumfy Tailz Warming/Cooling Dog Harness, Adjustable Neck

Purchased but returned for sizing issues. I'm going to reorder a size larger. The picture of the sizing info here on Amazon is not the same as the one on the packaging. So the Medium, that the info here says will fit my dog, is much too small. I'm attaching a picture of the sizing info from the packaging, which I hope will be more accurate.

GREAT DESIGN! A lot of cooling coats are designed so the cooling part is on the dogs back...not exactly the most efficient way to cool down a hot dog. This one targets the most important areas, the chest and underbelly. If a dog is hot, the best way to cool them down is by cooling their chest and belly (main arteries). This design does exactly that! My 100 pound french mastiff doesn't cool down very quickly, and it's hard to watch him panting like mad for an hour just to cool himself after a little bit of play. This vest is perfect!! He cools down in half the time :)

We got this for our epileptic dog because she tends to run hot in the summer and when she gets overheated she has seizures. She's a 40 lb pocket pittie with a dachshund shaped body (long and squat) so we originally ordered a medium but had to send it back and get a small. The small fits her perfectly! It's convenient, we just put it on her whenever we notice her temp is elevated and it cools her off. The harness is easy to get on and off. I love that the cool pack is against her chest where she needs it most. I wish the cool pack lasted a little longer but the ice pack is necessarily small and I'm not surprised by how quickly her body heat warms it up. I like that it's not overly cold and it doesn't seem to bother her. This chill harness does the job and it gets her temp down. This is not something I could use to keep her cool while she's out in the sun all day because the chill pack doesn't last that long, but it's perfect for that quick 30 minute cool down and once her temp is down she tends to stay cool for awhile. At some point I will probably try to find additional ice packs so I can just swap them out as they warm up and extend the cooling time.

SizingI have a 20 lb French Bulldog with a 16" neck and 21" chest and the size small fits him well. Since the maximum neck measurement for the size small is 16", getting the harness over his big head isn't as easy as I'd like it to be. A design improvement would be to give the neck straps clipping extenders like the chest straps. I didn't need the chest extender straps because my Frenchie's girth measurements met the minimum for the small. That means that getting the next size up would've been too loose in the chest but easier to get over the head.EffectivenessAside from sizing, I have to say that I've tried nearly every cooling solution there is for my dog and this one just OK. As other reviewers have mentioned, the cooling pack isn't very big, especially for the small-sized harness, and it doesn't stay cold for more than an hour. We live part-time in South Texas and the cooling pack hasn't stayed cold for more than 30 minutes during 15 minute walks in 75 degree Fall weather. That's not hot by any means for Texas weather, so I don't anticipate that the cooling pack will stay cold for more than 15 minutes in normal, 85+ degree Summer heat.Overall, it's likely a better solution if you live in milder weather and/or only plan on taking your dog out for a limited amount of time in hot temperatures. I'll be keeping the harness and likely layering it with a cooling bandana until I can find a more effective cooling solution for my active pup. It's better than having nothing.

Ordered two harnesses for my large older dogs so that they could march in a parade with my veterinary co-workers tomorrow. It will be a record high for the 4th of July in Washington. Representing a veterinary clinic in the parade, naturally I wanted to display heat safety as an example to others. Even went to the extreme of buying mushers wax to apply to their paw pads before fitting their booties so that they can safely walk on the hot asphalt. Unfortunately I received only one harness, so only one of my dogs will not be able to attend, which saddens me because they love all the attention they get from the crowd, and sadly due to age this would probably be his last parade. As a responsible pet parent I do all I can to ensure my elderly dogs enjoy the best life possible while I still have them around. I ordered rush shipping so that I could ensure the product in time for the 4th. Missed orders mean more than your know, even if it's a simple harness. To make matter worse, I really have no idea if my issue was resolved because I could not understand a word the gentleman was saying to me on the phone. Overall worst experience with Amazon yet!

I purchased this for my double-coated pug to keep him cool on walks in hot humid weather . Ideally, I wish the part of the harness that is closest to his tail could be tightened a bit more so it would hug his body more closely. I realize my pug is the exception to the usual 'baked-potato' body...he gets lots of exercise and eats weight management kibble with green beans to stay svelte. I had considered ordering the next size down which would have provided the closer fit at the waist, but his chest is very broad and the extra small harness just wouldn't work, even with extension clips. I plan to take the harness over the winter to my local shoe maker to shorten the waist straps just a little. Aside from that, the product works well. He's cool as a cucumber on walks during those hot days!
