Dear Springtime,

I started Anonymous on Longevity in April, and she will be 12 in September, and can already see an improvement in her actions. She is an active therapy dog and has been working since 1998, but I noticed she was sleeping more and more. Now instead of being down for the count at 8 p.m. she has a nap, and then is up and chasing the laser pen beam for a while at 11 p.m. I admit sometimes I want to grump but she is happy and moving freely even with joint issues in a hind foot, so we play for a while and then go to bed. My dogs have not shown any reluctance to eat the product on their kibble.
