"My 13 1/2 year old french bulldog wasn’t showing as bad symptoms as others have described, but he did display some behaviors that worried me. He used to stare off into space often, had a low appetite so he lost a few pounds, and generally seemed “lost” for a large part of the day. Sometimes I would let him out to do his business and he would forget what he was doing and just stand in the back for several minutes in one spot just completely still. I even had to call his name a few times for him to really “hear” me and respond to me (he isn’t deaf). He was almost a shell of the dog he used to be. I decided to do some research and give these a try. They absolutely reverted him back to his maybe 8 or 9 year old self. He’s always super alert, no longer has these “lost” episodes and his appetite has increased so much that he is eating more than he did even maybe a year or two ago! It has only been about 2month. My whole household is so happy to see this transformation. These supplements are expensive but so worth it to me. He will be on them for the rest of his life !"
