Questions & Answers

39 Customer Questions

What is the ppm copper content of this product?

Answer by Chewy • Dec 23, 2025
VetriScience does not test for copper in the GlycoFlex 3 Extra Strength Healthy Hip & Joint Chicken-Flavored Chews with Glucosamine & Green-Lipped Mussel Supplement for Dogs since they do not add any to the formula. There is, however, a small chance that there might be a very small trace amount due to the natural ingredients.

is there a medical difference between GlycoFlex plus an GlycoFlex 3?

Answer by Chewy • Apr 06, 2018
Both formulas have the same levels of Glucosamine and MSM. The VetriScience GlycoFlex Plus Joint Support Bite-Sized Dog Chews have added Chondroitin for pets who may benefit more from it.

What is the difference between this and the “plus’?

Answer by Chewy • Oct 15, 2020
Both products are proven a 41% increase in hind leg strength in just 4 weeks, but the VetriScience GlycoFlex Stage III is geared more towards seniors. VetriScience GlycoFlex Stage III is also recommended for dogs with a maximum need for joint and connective tissue support, joint and connective tissue support, geriatric and working dogs as well as to support normal recovery after orthopedic surgery.

is there a shelf life for opened and.or unopened packages of Glycoflex III

Answer by Chewy • Jan 09, 2019
The expiration date is located next to the lot number on all of VetriScience's products. On the bags, it will be on the back and looks like it came from a dot matrix printer. The lot number is 8 digits long, then a space, then 4 more digits indicating month and year.

My dog is walking again

My dog had weakness in her back legs making it so that she could barely walk a few months ago. Since she started taking these chews she is now walking and running

My dog had weakness in her back legs making it so that she could barely walk a few months ago. Since she started taking these chews she is now walking and running and so full of energy. There are other factors that could have caused this as we switched her food and she is on some Chinese herbs, but everything together has worked harmoniously to get our dog back.
