Bought based on positive reviews and wanted wind/sun protection. However, when placed on Shih Tzu, they crowd her eyes (no space between her eyes/eyelashes and the lenses) and the lenses FOG up. The doggles K9 Optix come with a 3d strap for above the head (the original 2 straps go under the chin and over the hear/under ears), which the pamphlet says will create space between the eyes and lenses. I haven't tried this yet. After reading about the foam padding inside the rims of the original Doggles (design looks like they create space without the need for a 3d strap) with ANTI-FOG lenses, wish I'd bought the original Doggles ILS Glasses X-SMALL - PINK FRAME - PINK LENS, but these looked less cumbersome. Too late to return or exchange.
Update: she's had trouble with her lashes, so I don't think she'll like anything confining her eyes.Get more detail about Doggles K9 Optix Sunglasses Xsm Pink Rhinestones.
