We both love it!

My dog absolutely loves the taste of th powder on his food, I had water and it makes a gravy. He literally nudges me near dinner time, he is so excited to eat!

My dog absolutely loves the taste of th powder on his food, I had water and it makes a gravy. He literally nudges me near dinner time, he is so excited to eat! I got this turkey tail mushroom because my golden has 2 lipomas and they were starting to get larger. He has been on it less than 2 weeks and the larger one has shrunk to almost half the size. Very happy with the results!

Started in August 2025, he had a nail bed melanoma removed in March. Didn't get it in time has spread up leg and shows that it has spread to lungs, so opted for no more surgery, he eats good, no limping and still plays with other dog. To make sure he eats it, I mix it with baby food he prefers sweet potato. The mushroom powder texture is powdery like cinnamon.

Terrible packaging

The packaging for this is terrible to close. When you order it shows a tub for the large size but when it comes it is a bag with a ziplock top. It is extremely difficult

The packaging for this is terrible to close. When you order it shows a tub for the large size but when it comes it is a bag with a ziplock top. It is extremely difficult to properly seal the bag. Should be a tub with a screw lid.

My lab, that eats just about anything, refused to eat her food with this on it. And made a massive mess trying to eat around it, super disappointed in it. I'd heard it was good for fatty tumors but if she can't eat it I won't know, and she has some bad ones.

I’m giving 5 stars, but wish we knew about it sooner. Our dog passed away within months of finding out about his nasal tumors. He didn’t love it but he was always a picky eater.

Been using for about two weeks, added a little water to the food with the powder as my dog didn’t like the dry dry powder. Licks the bowl clean now, and seems to be a lot chippier in his old step! Using this with the wuffles hip chews for large dogs!
