Additional notes... I'm wearing this on a whippet with a large face. I think the small whippet face would look good in yellow. For those who buy two, I will discount the shipping cost. This is a size S for long-nosed dogs. My beloved dog developed glaucoma, and I purchased this visor to protect its eyes, especially from UV rays when going outside. I measured the head of my Italian Greyhound (Iggie) and purchased the S size because it matched, but it was a little too big and didn't fit. In the case of an Italian Greyhound, it seems safer to ignore the measured dimensions and select the TOY size... Similar cases of size mismatch are also seen with other sellers. I think it's best for those who have experience using this product to purchase it again. If you are purchasing this product, it will probably fit a dog that is one size larger than the size described. Please check the website of the company that sells the product for details. I think the design and function of the product are really good, unlike anything I've seen before. The product has only been tried on and has been stored at home for a long time. In addition, we do not accept returns due to a difference in image, for either product.
