How does this go on?
Answer by ChewyDec 07, 2020
The Thermal Layer Onesie can be put on like any other pull-over style hoodie or onesie. We would recommend the following steps: 1) Place your pet's head through the neck opening. 2) Take each of your pet's front paws and gently guide them through the front leg holes. 3) Pull the garment gently down along your pet's back. 4) Take each of your pet's back paws and guide them through the back leg holes. This style has no zipper or closure that need to be secured.

What size for a pitbull
Answer by ChewyNov 19, 2020
For the best fit, we recommend measuring your pet and matching your pet's measurements as closely as possible to the sizing chart. To measure your pet's body length, measure the base of the neck to the base of the tail. To measure chest girth, measure your pet's chest around the widest part. If your pet falls somewhere between two sizes, we advise ordering the larger of the two. For the complete sizing chart, please refer to the photo below or click the “Size” tab, next to the “Instructions” tab, just under the product photos.

Great dog base wear

We call this our dogs track suit. Its perfect for use under her usual winter coat for added layers of warmth and coverage on most of her legs. Its also a great light weight base layer for cooler Temps, but when it's not quite cold enough for that winter coat. It's super easy on and off.

Makes my baby comfy and happy!

I originally bought her a size 18 She is a pit mix so she has a beefier chest Lower neck 18 inches chest 27 inches I have her back as 25 inches but I think I measured from the top of her neck Anyway the 18 was tough to get on and I could tell was not comfortable to her and did not fully cover her back Ordered the 20 inch and it is a winner Very pleased with the quality of the onesie Keep in mind this is like thermal underwear for humans It is a base layer

Don't waste your money

I can't see what the point of this item is. It's extremely thin fabric. There's no way it would do anything to keep my dog warm. It's not water resistant or anything. I also ordered the Kurgo Stowe base layer which is definitely a bit thicker and I would have kept that too if the velcro actually worked. I'm just going to order a fleece onesie instead.

Sizing chart off

Pekoe is 23” chest, 17” back, 13” neck, 34lbs. Based on the size chart, we got Size 18. Way too small! Then we sized up to 20, and while that fit better, it was still a little too tight length-wise for his proportions (his backs legs were restricted a bit). I think he could have worn it on walks, but for the amount of money it cost, I’d rather something that fits well. I had originally got this because I thought the full-body coverage would help him stay warmer on walks, but I think all you need is a good jacket (e.g. Ruffwear) to keep your dog’s core warm. This material is pretty thin anyhow.

Graphene fabric; stretches only a little, lengthwise

I read all the reviews before purchasing this re fit and re the fabric, and here are my thoughts: 1) There's variation in the same size, which means that quality control is not as good as it should be. 2) People's definition of what fits on their dog (how tight, how loose) is relative to their ideas of how clothing should fit a dog. 3) Dogs are the most morphologically diverse species on the planet, meaning that their form (size and shape) varies incredibly. Factory-produced clothing is never going to fit every dog precisely, as there's a 2 inch gap between sizes. e.g., if your dog's length, depending on exactly where you start to measure, could be 12.5", which makes a 12" onesie a little too tight, but a 14" way, way too big. Then there's how chesty they are, like bulldogs and greyhounds vs really slender builds. Ideally, manufacturers would provide more sizing options, ie, 10", 11", 12", 13", 14", etc. Unfortunately, they don't. That said, I have seen that Hurtta provides additional size options, such as 10XS, 10S, 10M, which helps out for the chest and leg lengths, but not the back lengths. Since the fabric isn't stretchy enough, it would be logical (but annoying) to buy several of the same size and see if one was made slightly larger or smaller. Or take it to a tailor and have them fit the onesie to your dog, obviously driving up the cost. Re the fabric, it says that the fabric is graphene. There is a honeycomb print on the interior of the fabric, which I believe is the graphene layer printed onto the fabric. According to my research, graphene is excellent at conducting heat. Therefore, I think that this onesie is meant as a base layer, underneath an outer layer. If you think about copper pans and how they heat up and cool down quickly, graphene is something like that. (I'm just relaying what I read about it.) Re price, this is on the high end of dog clothing, along with Hurtta. We got the Hurtta thermal onesie, but the elastic obstructed my male dog from peeing. Not sure where all the great reviews came from, as we tried about 3 of them, including the different variations. Also, I don't think the fabric on the Hurtta one has any special heat retention properties.

a bit big but what i was looking for

it’s on the expensive side, but great for layering under jackets and stuff. i mainly wanted to add some protection/warmth to my dog’s legs and belly, so this does the trick! it runs big (i think i measured correctly), but the longer sleeves worked out for the aforementioned purpose, and a five minute sewing adjustment made the length fit better.

Good thermal base for layering

Thin stretchy material, well made and good for layering. Measurements were accurate. Keeps my pup’s legs covered in the cold and he can still pee! I use this underneath a more substantial puffy vest for my 11 yr old Boston terrier.

Perfect Solution!

My 30lb Beagle is skinny and in the winter he is chilly even inside but absolutely miserable in the cold even with a coat. I got this to cover his back half + legs when going outside in winter. The material is stretchy and soft, like human athletic wear. I ordered only 1 size up from his measurements: size 20 and it’s perfect. Not too tight or baggy! Comes on a very nice hanger.

Not recommended to keep your dog warm

This "thermal" is equivalent to a long sleeve shirt. Not recommended if you're trying to keep your pet warm on a walk outside. Highly disappointed especially for how expensive this was. Putting one of my sweatshirts on my dog keeps her more worm than this "thermal".

Ben love his long johns

This is so great under Ben’s coat or alone on our walks. It fits him snuggly and not only keeps him warm but, I believe, gives him a little more confidence on our walks. Ok, so he doesn’t exude confidence in this pic, it was his initial fitting. He love his long johns now.
