This is the truth, our blessing is finding PawFriction. Our dog is only 9 pulled a muscle in her leg, got well and 6 months later she did it again, stopped running, stopped eating, and stopped playing altogether. Started sleeping in another part of the house. We were almost to the point of putting her down. We purchased PAWFRICTION and had the tech at our vet clip the hair and put it on our Annie, she is 2 days later walking around, feeling frisky, day four she is playing with her toys.
