"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."†

natalie s. My bulldog's (13 year old) back legs started to fold in on themselves and we tried multiple things with the vet. One day someone told me to try this product. Hand on the bible, her back legs have straightened out... I have tried to assign any other reason for this and the only change in supplement, diet ,or meds is this supplement. I am so impressed that I bought some for my dad that has Parkinson's!
