I put Four Paws Pet Dental Liquid in my dogs water dish every day. My vet recommended it to me after I asked for some advice on how to brush my dogs' teeth. They won't allow me to brush them, so I use this instead. It gives me peace of mind in between dentals and taking them to groomer to get their teeth brushed. I would recommend this product to anyone who has problems brushing their pet's teeth.

I have never used it or heard of it but if you bought it at a pet store and it's made specifically for dogs I'm sure it's safe. Just be sure to follow the directions carefully.
