Sizing is way off for chesty dogs.

On paper I bought the right size, but it didn't come close to fitting my pit/lab's chest, even adjusted all the way up. But I'm giving it three stars for quality. Even though I'm sending it back, I have to acknowledge that it's well made.

I ordered the XL size and it's more like an XS. I compared my dog's measurements with the ones listed and based the size choice on that, the size I received is completely wrong.

I measured my dogs waist as instructed which measured 30 inches so I went with the XX-large and they are huge on her. Not only are they big around waist, they do not fit her properly from her tail towards her head, it's just big all over and sags off her.

Way too small for chest, size chart is too far off.  I would add ten inches to measurement to be safe.

I have a five pound dog and ordered the XX Small because those measurements were correct for her. I received this harness and the quality is superb, however the harness itself is soooo tiny that it's like a small saddle on her back. The fit is very awkward and it looks completely strange. I have other service vests/harnesses and wanted to try this one, but the sizing is all off. Do not understand why this is or how it worked out that way, but I would be careful with measuring your dog for this and definitely order a size way up. You may also have to alter the straps a bit then. Overall, I am disappointed. Amazing quality, horrible sizing.

I ordered the 2X for my grand dog who weighs 70 lbs and usually wears a 2X.  It fit my 15 lb dog.  I reordered an 8X per customer service and it was still too tight.  I will call to return it.  It is a cute hoodie and would have liked to have my two dogs to have matching hoodied

It's a nice sturdy harness but the sizing is inaccurate. I measured both my dogs and bought 2 a large and a medium only because my friend said they run small.  Turns out the medium is way too small for a 11.5 Neck and 18.5 Girth and the large is to big I had to return both. Which is bad because I bought them as prime and didn't have to pay shipping but when I returned them they charged me shipping which came out of the cost of the product. So I didn't get back what I paid for it which is totally unfair should have received total about back and because it's prime return shipping should be free.  Not happy at all!

Very important to measure your dog correctly and not go by the weight guidelines. And the measurements suggestions are inconsistent as well. I have a 19# Westie, so I bought the small based on her weight, especially since she is much closer to the low end of the weight range for that size vest. It doesn't even come close to fitting her. None of the straps meet at all. I cannot imagine any kind of 30# dog that this would fit. But I'm hesitant to buy the medium, because it seems like it would be too long for her body, as it is supposed to fit dogs up to 50#. The top customer review reported that the packaging states the small fits up to 24" torso, but my dog measures 21" and it's not nearly big enough. Aside from that, the vest seems very well made.

VERY cute, but I was very disappointed with the sizing. I bought an XXL for my puppy (who is currently at about 40lbs) so that it would still fit him once he was full grown. I'm not even sure that by the time cold weather rolls around that this will still fit him! The XXL claims to be for dogs 58-80 lbs, but there is NO WAY this would fit a dog that large. It would not even fit over the head of a dog that size! SUPER unhappy that I will have to return this. If you have a dog larger than 40 lbs, DO NOT BUY THIS.

They are nicely made, but is half the size of my dog's paws. My dog is a 65 pound staffy and she wears xl clothes, so I figured since she wears xl clothes the xl shoes would fit. I showed my dog the shoes and she went hysterical because she has a new thing she can wear (she loves clothes and harnesses, but it has to be pink. I know she's weird) She was heart broken when they didn't fit. I've measured her foot while standing and the spand is 2 1/2 inches, and like I said the shoe was half her size. I'm disappointed that they were too small.

I ordered a size 7 for my 4 year old husky that is a medium/ large sized dog but these were so small!!! sizing is definitely off and is suited for smaller dogs.

I purchased a medium and it fits like a small on my dog. There needs to be a size chart on the weight for dogs and the size that fits them posted.

They run extremely small. I order two for my two not quite 10lbs Chihuahuas and thy do not fit.  Now what do I do with these shirts.

My dog is a husky mix with a deep chest and this costume was too tight and constricting, despite having measured my dog first for the appropriate size. Instead of reordering the same shirt in XXL, I opted for the Uhura skirt in XXL, which has a more open construction. I still had to cut and resew the sleeves, as they were too constricting for her to walk. Be aware that these shirts are not designed to fit every dog body type, or be prepared to do some tailoring to make your pup more comfortable.

Medium doesn't fit my 38 lb dog.  They need to add chest measurements if we are to order the proper fitting coat.

I ordered a large, and it is extremely small. I donated it, as there was no way it would fit my medium sized dog.
