I had the opportunity to try out and review a teeth scaler for dogs. I have a chihuahua and I try to brush my dog's teeth on a regular basis. Even with that, my dog always seems to still have tarter buildup. going to the vet to get his teeth cleaned can be rather expensive so I jumped at the chance to try this to see if I could do it myself. It seemed like it worked pretty well. I got the majority of the tarter. I probably could have gotten more, but I didn't want to do any damage or hurt my little one. This was a little difficult to use by myself, but once I had someone to hold and comfort my dog at the same time, this was pretty easy. I received this item for free in exchange for an honest and unbiased review.
