Canident reduces the tartar on your dog's teeth in 5-8wks or your money back. No quibbles.
Canident is a blend of sustainably-harvested brown seaweeds that are farmed out in the cool waters of the Atlantic off West Ireland. The plants selected contain unique polysaccharides that studies show soften and reduce the tartar on your dog's teeth over time. We take great care how we dry our product, preserving these good bits. We are so confident Canident will do the job, we offer a money-back guarantee it will do the job. The reviews don't lie! 
As always, please remember, dirty teeth is first and foremost a dietary issue, usually a lack of abrasion in the diet. In this instance, nothing replaces a nice, raw meaty bone. Here's how to feed raw meaty bones safely.
Giving such a seaweed-based product is not just about teeth cleaning, however. Seaweed is a popular food supplement for dogs as it is so rich in vitamins, minerals and antioxidants that boost your pet's health.
