"Lion's Mane for dogs helped my pit bull be able to walk better and she wants to play now. She was walking like a drunken sailor, and this has also improved. I also take Lion's Mane and have noticed improvement in my memory. I think anyone looking for medicinal help should give these a try. For my dog its improved her quality of life. I took capsules apart and put on her food. Her walk is improved and she's not going off by herself so much."†

"My dog had a bout with vestibular disease last summer, and his hearing has been going ever since--to the point we would have to yell to get his attention. After about 2 weeks of giving him Lion's Mane capsules, he can hear me again when I talk in a normal voice! It is really miraculous! He is almost 17 and I am so excited to find a supplement that has seemingly taken years off his age."†
