Kumfy Tailz Warming/Cooling Dog Harness, Adjustable Neck, Medium, Black

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.

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.

This is exactly what we needed for our little barrel-chested Boston Terrier. He's short but stocky and we have difficulty finding coats and cooling vests to fit him. By the time we fit his chest, the garment is always too long. And if a coat or sweater looks like it fits, it's inevitably too tight for his chest. We're hoping to use it as a warming pack as the weather gets cold since we can't find a well-fitting coat or sweater.The Kumfy Tails harness is adjustable around both the neck and belly/chest area so it's a great custom fit. I do wish that the cold pack wasn't as narrow and covered a bit more area on his chest and belly, which is why I only gave it 4 stars, but considering the size small is so adapatable to fit a wide variety of breeds, I guess they need to err on the smaller side for longer skinnier dogs.I think this is the best option for owners of stocky smoosh-faced dogs who have a hard time keeping cool - it'll be the best fit for Bostons, Frenchies, Bulldogs, and Pugs for sure.

I have a big problem here!I ordered 2 Kumfy Tailz warming/cooling Dog Harness for my yorkie in 2 diferent sizes, x-small and small to see which one fit on him because he is between sizes so....I received the x-small harness on Monday June 3 and it was too small for my dog, I received the Small size one today BUT the product was packaged in a zip-lock bag WITHOUT the gel-kumfy pax in it!This product is USELESS like this!Also it looks like they sent me a product that was previously returned because the harness has white dog hair on it.Very dissapointed......UPDATE:After I received the first harness without the kumfy pax AMAZON send me another one which I received today WITHOUT THE "REUSABLE KUMFY PAX" AGAIN!Is this a JOKE?At this point I don't want to return the product I just want to receive the gel-pax!UPDATE:Today, Sat June 8 I finally received the "Kumfy Tailz with the Kumfy Pax" in it. The complete product!I tried already in my yorkie and fits nice ( small size ) and is lightweight.After all, I'm finally happy with the product.

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!
