Kors is my rescue and he is anxious and worries a lot. He was a stray and didn't have the easiest life before he joined our family. I had him on a prescription medicine that helped a bit but not enough. Kors is able to relax and not always be on alert. He has always been wary of new dogs and his reaction is to immediately start growling. Yesterday when out in a public place with other dogs around he happily went up to a much bigger dog, tail wagging and no growling! I feel good knowing he is getting a healthy natural treat!
