What better way to provide your dog with the potential benefits of Glucosamine?  Although the benefits for animals, such as dogs (and the jury is still out on humans too), are still argued, there are no drawbacks to providing your dog with Glucosamine.  If your dog loves peanut butter, then he or she will love these biscuits.  I selected this brand due to the natural ingredients as well as limited ingredients - there are no fillers, etc. in these biscuits.  Each biscuits contains 500mg of Glucosamine.  I provide my dog with two a day for his size (he is a large black lab, who often runs with me, as well as is an avid swimmer and walks an average of 3 miles a day).  All I have to do is say "biscuit" and he knows what he is getting.  Although if it is past his usually treat time, my dog is sure to remind me!
