“Our 14-Year old terrier mix, Kacie, has begun to creak audibly in her old age. She has arthritis and other age related maladies. About 5 months ago we heard about K9-RX from our son and daughter-in-law and decided to try it, hoping that it would make our “dog person” more comfortable. Not only does she definitely appear to be in less pain now, but some of her more youthful spunkiness has returned. She plays ball again……something we hadn’t seen for quite a while! Thank you, K9-RX, for giving some spark back to Kacie!”
