These little fingertip toothbrushes are great. They're effective and really affordable. The brush part is very soft, so it doesn't hurt your dog's gums or lips (which you will almost inevitably end up scrubbing if your dog is fidgety like mine).The only downside for me is that the material that surrounds your fingertip is not very stretchy. It's not an issue for me, but they're tight on my husband's fingers and can start to cut off his circulation. If you plan to use these and you have big ol' man fingers, they may be a bit snug.However, you can't beat the price, so we'll keep using them for sure.
