He is 13 years old and has been slowing down from an incredibly fast paced life. He would run 10 miles without blinking in his youth. Now he is on maximum strength cbd and enjoying nice long walks. People always comment on how young and spry he looks and seems. Honestly it has to do with a good diet and every day cbd Mainteance. He is one happy 13 year old German Shepard. Thanks for keeping him going.
