6MILES 1 Pcs Light Brown Adjustable Washable Comfortable Funny Lion Mane Wig with Ears for Dog and Cat Costume Pet Fancy Hair Clothes Dress for Halloween Christmas Easter Festival Party

Q: Will it be uncomfortable for my dog to wear it?

The material is very soft, my dog likes to wear it, I use it to take photos for Halloween or other occasions. It is so cute on my dog. I recommend a friend, it's worth it

Q: Will it fit a small dog? My dog is 17 pounds, his neck is 12 inches and the circumference around his chin/top of head is 15 inches. Thank you!!

I can’t say for sure but my dog was 85 lb golden retriever and it fit him perfectly. I would think it would cover the entire 17 lb dog, however it is supposed to be adjustable according to the description. You may want to check that out before you buy.
