I noticed these chews don't contain Chondroitin, unlike most of the other glucosamine products available. Is this something I would have to find to supplement these chews?
Answer by • Aug 04, 2017
The Chondroitin is naturally derived from Green-Lipped Mussel.
What is the difference between these chews as compared to the tablets? We have our senior dog on the tablets which have to be crushed and mixed with soft food for her. Are these chews soft and smaller than the tablets?
Answer by • Nov 07, 2017
The chews and the tablets have different dosage and texture to fit your pups needs. The chews are smaller and have a chewy texture.
What are the differences between the VetriScience GlycoFlex and the VetriScience VetriFlex line?
Answer by • Jul 31, 2019
VetriScience VetriFlex combines the advanced formula in Glyco Flex® with ingredients that have been extracted using Phytosome® technology and is part of the VetriScience Pro Line which is only available through veterinarians.
