Review (5/5): Really easy to use and clean.  Great for small dogs
I had another version of this before, but the bristles were much denser which made it harder to dry quickly. If it did not air out it would mildew. This one dries much faster and seems just as effective. My dog likes it much more than your standard dog toothbrush, and quite frankly, I am surprised dog toothbrush companies are not making this style.
