I have seen a significant increase in Buddy and Lady’s functioning while using the Relief and Revive chews. As for Oliver and Shadow, for them, we have been using the Relax chews as they tend to be more uneasy about things going on outside (deer hunters, farmers finishing the harvest, and more and more mail being brought up to the front doorstep) and I have seen quite a difference in the way they have been after taking these chews. Thank you so much Vital Essentials! – MacKenzie
