While Dasuquin is an Excellent Product I will never buy it from Amazon again. Upon opening the package I noticed the chews were dried out and looked old. Upon further inspection of the package I noticed a small tear. The package was not expired. Due the fact that I had opened the package I did not try to return them. I threw them out because I was afraid to give them to my dog. I felt they one were not fresh and two they may be infested with insects or someone may have done something more sinister. I will never buy anything consumable by pet or human from Amazon again. Almost $80.00 down the tubes.
