Didn't work on our puppy
Our vet had recommended the higher dosage Zylkene for our 13 year old Setter who developed anxiety with the addition of our new puppy. We enjoyed excellent results with her. I ordered the lower dosage product for the puppy as he was extremely hyper, but it yielded no results whatsoever. Giving the product the benefit of the doubt, I will now try the higher dose which I have re-ordered for the old girl, on the pup as his weight has now increased, and see will this make a difference.
