I purchased this not really knowing how good it would work but I have been putting into my dogs food daily. My daschund has serve allergies so I’m hoping this would help. Vets are so expensive but your company offers very good products so always willing to try.

Started using this years ago on my epileptic dog since he was on so many anti-seizure meds and I didn't want to put even more chemicals into him. Never had an issue with parasites. When we acquired a stray who was severely under weight and covered in fleas, I started giving this to him as well. Within 2-3 days, we were driving back from the store and the dogs were with us. All of a sudden, Leo (the new pup) started heaving. By the time we pulled off the road, he'd thrown up a large, gross looking white worm on the console. Once he got rid of that, we've never had any further problems. I still give it to him daily as a preventative.

Awesome product! Slowly but surely my Kiki's warts are drying up from the virus. I believe the virus is gone and he will not have any more warts once these dry up and go away!

Went through a rough "hot spot" spell this past summer, and using BlackLeaf tincture definitely helped us turn it around. Our doodle is bothered by allergens, and got an overgrowth of yeast/fungus in her ears and on her skin. Adding this to her food, along with using Ox-E drops and topical, helped us get her back to normal in just a couple of weeks.

When we adopted our dog from the shelter she was on a.lotnof meds due to just coming off the street. She ended up being very itchy. The vet prescribed at least 3 different thi gs which did not work. The vet said she had yeast in her ears. When doing my own research I learned that meNt yeast in her gut. Nzymes products along with Dr. Marty's dog food has been a game changer. I don't know whatni would do without it. The results have been so amazing.

This is one of those items that is hard to tell if what it does or if it is working...but I can say I gave this in varying doses (due to shared food/water,etc) to my 6 dogs. It did seem to provide multiple results. I would absolutely buy this again. Wish I knew if this could be fed to my livestock, I think it would be good for them too

Using this as part of the yeast detox program for over a year and a half. The entire system is working. Ivy's skin is much better and, one day, it will be perfectly healed.
