Even though this product is NOT the traditional rawhide chew and therefore doesn't last long, I buy it because it contains  prebiotics which eliminates the need for yogurt (or other medications)mixed in dog food or treats (per vet instructions)due to my dog being on frequent antibiotics for UTI's. Great price with free shipping.  This product sells for 24.95 at Petsmart when you can find it.  The only problem I have with this product is the package seal-doesn't seal properly once this package is opened. Would like to see this product sell as save and subscribe to prevent monthly ordering.
