What Pet Parents are Saying
My Dogs Love This Stuff
"I gave my dogs other mushroom supplements in the past. One dog BARELY touched the old one. This one, she gobbles it right up. My other dog gets SO excited when I open the bottle. I'm assuming she gets excited by the smell because of the bacon flavor. But this stuff gets immediately eaten, every bit of powder licked clean off the plate."

My Dogs Approve
"I have several senior foster dogs with various conditions, so this is targeted for their ageing issues. My older chocolate lab has more energy since he's been taking this, and as long as he keeps acting like a puppy, I'll keep giving it to him. They seem to approve the flavor."
