Our dog is skinny and long so we got the xxl for the length but might have been better with the xl. Otherwise it was nice and cozy and she seems comfortableThese PJs are very fuzzy and look quite warm. They wash and machine dry easily, and are easy to put on as long as you have a cooperative dog. I took off one star, though, because the arms/legs are long for my breed-standard Westie even when I turn up the cuffs. In fact, she usually manages to get one leg free of the PJs during the night.It looks as visually advertised however, it appears each item size differs.,IE: Shirt and sweater X_Xl is extremly large and onesies, a size smaller than advertised. My dog wld take a medium size based upon chart, so I went up 1 size-as recommended!! The only reason i'm keeping it is because the positive out weights the negative-length short even for a standard size doxie. Nonetheless, it is soft, warm and very stretchy....and my furbaby likes it so far!Cute. Good quality for the price. Would buy againGot this for my chihuahua in a medium. She's about 9 lbs. Very cute on her. I roll up the legs once.My dog is a medium size dog in clothing bought in California. This item is about 6 inches too short. I recommend buying a larger sizeReally soft, stretchable so it’s easy to get on and off. Doesn’t have a hole for a harness so you would have to use a regular collar or put a harness over the onesie. He’s 5lbs and rocking the XS. Perfect size for him. He gets showered with compliments all day when he’s wearing any of his FitWarm clothes.I cannot rave about this jammer set enough! My 6lb chihuahua usually wears a sweater when it gets really cold. She loves to be warm under a blanket 24/7. To the point of, if there isn't a blanket for her, she will whine until you get one. She does good with sweaters but doesn't love them. When I put this set on her, she tucked her tail for about a few minutes then as she got warmer she relaxed & hasn't stopped napping since! She loves it! It's long enough to cover her body & is also roomy enough that she can move without restrictions. We got her a Medium & it was perfect! Loose enough not to strangle her & long enough to cover her entire chest & back to her tail. If she pulls her feet in while napping theres enough room for the legs to cover down past her toes. I can't rave enough about this product. Great material, full fleece & exactly as pictured. It's a little more grey than green, but that's not a gripe! We love it! Will definitely be buying more!Just as advertised in the pic , keeps my bald cat nice and warmFast shipping. A bit smaller then expected. Well made. Looks great. Warm and durable material
