Preserving Doggie Biscuits

My advice to you is not to use any preservatives period, simple dehydrate your treats, They are far safer and better for your dog in the long run,
Many people don't seem to realize how much these two "Natural" preservatives are being used, Our dogs are getting overloaded on these "Natural Vitamins, What kind of problems is this going to lead to next...
