Outward Hound Kyjen Dog Elf Hat, Small

I like this hat. My dog doesn't. Still, it did what it was supposed to, at least until my little guy shook it off (about 2 minutes after it was on). I don't think there's any way to make sure it stays on my guy. The strap is fine and everything, and is adjustable, but if my dog doesn't want to wear it, he can easily get it off.In terms of sizing, I purchased the large, and it fit my 50-55 lbs boxer puppy. I bet it would fit him until he's full size (probably around 80 lbs).Also, as a side note, my dog eventually decided to turn the hat into a toy and chewed through the elastic strap. It is, however, now one of his favorite "toys".

This was a totally adorable little hat that I wish my dogs would have actually worn. I have one golden lab and one black lab, and the ears looked odd on my black lab because of the different colors - so think about that too! They were both able to pull the hat right off...

I bought this for my persian cat for christmas. I bought size small and it fitted my cat's head perfectly. The band around the neck was a little tight, but that's the only thing I didn't like. My cat looked absolutely adorable in this. She looked like a little elf. I took nice pictures of her and that was the main reason I bought this. So I'm very satisfied, now I can make a nice poster of my cat and this hat :-)

The top part of the hat will not stay up without being stuffed with paper first. But if you can get your dog to keep it on its head, it's adorable.

This joined a herd of puppy hats for the season and was my immediate favorite. Clever, colorful and made well. One star deducted for the drawstring-style chin cord -- the cord worked fine whenever the pup had the patience for it. Keep an eye peeled for the dog review once he gets older -- after a year or so he might like it more than me

The product itself is super cute but it certainly didn't last long on my pups head! One blurry photo was all I managed. :)

Yes, it is difficult to stay on. Especially when you have a dog that hates wearing anything! But worked out very very cute for my Christmas picture 2 years ago on my little yorkie! She's about 8 lbs with a tiny little head.

I bought a small for my 22 lbs dog. It didn't fit...a bit tight on her. Had to return and get a large.
