I purchased the Googly Eyes wrap / small for my Cavapoo, Tigger. Installation was easy. I received many laughs when Tigger was wearing the Goggly Eyes goggles in his doggy backpack. Only negative is that the lens wrap is expensive and why I gave it 4 stars. As I already have a smoked lens, I would hope to pay only $10 per lens wrap and not the $23 they charge.
