Personally I have never and will never feed those treats.
Reason 1: They are made by Nutro, who makes multiple less than well dog food products that I would never feed.
Reason 2: They do not digest.
Reason 3: They cause intenstinal blocking
Reason 4: After 12 hours of giving your dog one they can still choke up large pieces still intact, because they do not digest
Reason 5: Greenies has paid for surgeries for some dogs, but still say their treats are safe.
Reason 6: The ingredients. You might as well let your dog eat flavored plastic.
