Best teeth cleaner for dogs. My dog is almost 8 and is a cross between a poodle and a schnauzer that weighs 19lbs. I have been using this on him 3-4 times a week morning and night, 1 squirt in each side and his teeth are so clean. I have never had to have them professionally cleaned and we just got back from the vet and they were so impressed with his teeth. They said just keep doing what your doing because it works! So there's the best recommendation I could give you. Plus it's super easy! My dog can care less when I spray it. He barely lifts his head then just goes right back to napping when I spray it. I have tried to add pictures to this review but Amazon says there's something wrong with the review like I'm somehow posting wrong info. If you want pictures maybe you can text me? not sure how to do it now.
