Real Pets. Real Results.†

"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."

– Verified Customer

"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."

"We love using the Lion's Mane Formula for pets in senior dogs - it really helps them maintain function and the human-animal bond with their family! Signed, a rehabilitation vet"

Life saver

This product is amazing!!! My 15yr old chihuahua was diagnosed with dementia,and her condition just kept deteriorating. Whit in a few days of starting her on this I could see drastic improvement in her behavior, appetite and muscle function. This literally has given me my dog back. She still has little moments of confusion but her quality of life has drastically improved!!
Also my pitty had a bad fall and got a severe concussion. She was barely able to walk, was in and our of hospital for almost 2 weeks, partially
paralyzed on half her face and extremely disoriented for months. Once I found this, same as my other dog in days saw massive improvement. They both have been taking it daily for 2 months now, I feel like I have my girls back to normal. If I could give 10 ⭐️s I would!!!

Frequently Asked Questions

There are several options for giving capsules to your pet. You can open the capsule and sprinkle the powder over their food, or you can hide the whole capsule in a pill pocket or another tasty treat such as cheese, a small amount of butter, or a meatball.

Administer 1 capsule for each 20 pounds of body weight once daily or as directed by your veterinarian. 

They can be given with or without food. Many pet parents find that administering capsules with meals is easier and helps ensure consistency over time.
