I have three dogs, a small and 2 large. I got the medium and had my 11 lb shih tzu wear it and it was a little loose. I had my 70 lb pitbull and it was tight on her. The medium is true to size. The shirt is perfect for Christmas! It has adorable pictures of Santa, snowman and candy canes. Very stretchy polyester, thin and soft. If you stretch it too much you lose clarity on the images. I would have my shih tzu comfortably running and walking with the medium. The smaller would have been better fit for her little legs. Other than that, very pleased to have my dog join the Christmas attire.

OMG what can I say. These pjs are super cute. Good quality, and material is soft. I got the size Large for our family mix lab and that boy is thick thick. I honestly thought it was going to fit him. But we were wrong. It fit him perfectly and he looks so adorable in it.

If cute could be bottled then this would fill your pantry. I don't how much Archer likes it, but it's the best dressed he's ever been Easy to put on. Fits great on our 25 lb mixed breed. Highly recommend this for your stylish four legged family member.

This is a cute PJ for any pet during the holiday season. Usually when we try to buy our dog clothes, they are scratchy and uncomfortable for our Canelo. This little sweater is thing and smooth even after several washes of use. I will definitely be buying more in the future.

This pajama top for dogs is SO STINKING CUTE! Also, it’s insanely soft. Definitely a perfect little light weight top for your fur baby. I love the fact that I can match him too if I want (which obviously I do). This is definitely worth the purchase. Very cute & fits well (true to size). My dog is a 50lb golden doodle and I got him the large. Perfect fit, not too tight or loose.

These Jammie’s are so cute in my Ellyie! She is about 49lbs and barrel chested, they are snug but she seems to like them very fitted! She wears them around and doesn’t try to take them off! Amazing! It must be because they are so soft and light!

This is such a cute item for your dog to wear around the holidays. I like that it is form fitting yet stretchy. That way it is not hanging all over the place and getting dirty when dogs do what dogs do!

The shirt fit my dog so well! She is a larger dog and the shirt fit perfectly. The material is soft and she was happy to wear it, since we generally keep her hair short! I love the pattern on the shirt too and the color does not fade after washing.

This pajama set is just SO cute! Super soft and looks adorable on my pup! The material is quite this, but it works well for my dog. It’s stretchy and soft too. The fit is nice and the medium fit my 18 pound Sheltie (who has tons of hair) perfectly

Super cute doggie jammies. I got a size medium for my 40lb Brittany and this was a bit snug on him. So we put it on grandmas tiny dog and is a much better fit. So I would definitely size up! But the pattern is really cute!
