These are on the top 10 things I wish I had bought years ago! I have 3 chihuahuas… like 4-5lb chihuahuas. It’s so hard to brush their teeth. My finger is way too big to stick in their mouth. I have tried baby toothbrushes, other finger brushes with grips, using just a napkin but all are too big. (I use coconut oil, as their toothpaste). These were a HIT!! I can just use the tips of my fingers (using 1 on my index and 1 on my thumb) and not have to stick my finger in their mouth. This is the first time they accepted getting their teeth cleaned. They always come running for the coconut oil but back up once the teeth cleaning starts. Not tonight! I can tell these are scrubbing & gripping their teeth and actually cleaning them, unlike anything else I have tried. Highly recommend. Also, they sent one of those super soft silicone finger brushes with the soft teeth. It’s also amazing! Idk if I’ll be able to use it on back teeth bc of the size but if you have dogs bigger than 20lb it’s also ideal.
