Breed:One is a CockaPoo, One is a Westie, and One Westie "Wannabe"
I never tried these Doggle Ionizers before - never heard of them before either, but it seemed like a great idea to try, and the price was right. Fresher air is always better. They seem to be working well. However, I think they're a bit bulky for small dogs - example: Westie and Westie Wannabe (crossed with a Chihuahua or something similair). The Medium sized CockaPoo doesn's seem to mind. It's all new to my dogs and to me. Great Idea. Great product.
