These pajamas are great for my 6 lb Yorkie. He likes wearing them. They keep him nice and warm. The fit is perfect. A stretch material and they confirm to his body. He wear them when I take him out for his walks in the winter. This is my second pair. Would be nice to have more colors. Excellent product.Super cute, keeps him from nervous scratching and he’s very comfy. This keeps him from stealing all my covers too!? Looks like a little bumblebee ?I gave it 2 stars on light weight because it is a heavier knit. I am glad it is heavier. It helps keep my dog warm.My westie has to wear clothes nearly all the time due to skin allergies. In the past, I've had to order custom outfits for him. I saw this and thought I'd give it a try. OMG, it's really nice quality. The fabric has some stretch to it. It is super cozy and soft, inside and out and the size is perfect for my 19.8 lb guy. (XL). It fits very well. It came in a nice zip loc bag along with care instructions and contact info should you have any issues with the garment. Aside from fit and finish, the design is adorable. It looks and feels much more expensive than it is. I just bought 3 more!Keeps my dog warm at night during this cold weather!I'm usually not one to write product reviews but, I mean, look at how cute she looks in this outfit! This is her 3rd PJ from this brand and we just love it. The other 2 are XL but this is an L and it fits perfectly. She's 12 lbs, for reference. The material is super comfy and warm and she does not struggle with this on at all, in fact, when it's morning time and time to take it off, she growls! I would highly recommend this brand and products. Will likely purchase a few more.I've tried a couple of different onesies/pajamas to hold the diaper in place and hide the bald spot on my incontinent senior pup. This one is my favorite. The material is thicker and warmer than Tshirt material, but stretchier than the cheap fleece used in other onesies.. It's snug enough to hold the diaper in place and give my senior pup a gentle hug (which has a nice calming effect) but stretchy enough that I can get him into it without a struggle and he can move around in it comfortably once it's on. And of course, it has all the proper openings so that the pup can go for walkies (no diaper) and still keep the bald spot warm.Soft and thick material. My pup sadly had outgrown it as it is very small (it fit him when he was under 3 kg and he is an Italian greyhound) but it is very good qualityHERMOSÍSIMO! Superó totalmente mis espectativas. Mi perrito se ve divino, súper súper bonito de verdad, excelente calidad y entregado antes de tiempo. :)
