Missing Link is a vitamin and mineral supplement for pets. It gets mixed into their food once a day.
I have three little fur girls. One is 15, one is 12, one is 2. The 12 year old had bilateral knee surgery three years ago. I had started them on Missing Link Plus (hasglucosamine) about 4 years ago. When the surgeon wanted to give us a prescription for a glucosamine supplement, I told him we were giving her Missing Link and he said don't bother with the supplement. And she is doing extremely well ever since. Also, both of my senior girls are in great health and have excellent coats (yorkshire and silky terriers in full coats). I fully credit Missing Link with their great health.
