I have several of these, all but a couple have not been used from. This is an amazing rinse, unfortunately I won't be needing them anymore :( I stocked up & bought several bottles...this is pretty costly from the stores, however since I won't be needing them, I am willing to let them go much cheaper than they are worth, because I know there is some little dog out there who may find relief & benefit from them, just as my dog did.
