Review: Love their products-highly recommend! - Long review ahead: First of all, my very large boy, 106 pounds- Great Pyrenees mix has been battling MCT for the past 2 years. He had one tumor removed on his leg 2 years ago. I went into research mode looking for more holistic ways to treat him after surgery. We used the 7 Shrooms religiously, and I added Turkey Tail mushrooms a few months later. At first I was very frustrated because I could not mix it in sufficiently, as another review mentions. I learned to add the scoops of mushrooms into the bowl and then slowly add warm water and slowly stir until it’s runny gravy consistency. I then add the dry kibble to the bowl and stir. He eats it right up! Unfortunately, I had a medical emergency and was buried by medical costs so I stopped purchasing and giving him the mushrooms, and he developed another MCT (whether this is related to stopping the mushrooms or not I don’t know, but he was doing GREAT on them). He had surgery 10 days ago and the pathology revealed very slim margins. In doing more research, and considering it is spring and he has horrible allergies also requiring cytopoint injections, I wanted to find something to boost his immune system. I read that this has 200mg of Quercetin, which is great for fighting cancer cells. He’s been taking it a couple of days and he loves it. I add it to the others and he doesn’t bat an eye. I love this company and that their mushrooms are grown on wood and are third party tested. I know they are a bit pricey but worth every cent imo. I will update when we have used a few months.
Review: Pretty good product, but depends on the dog - I want to start by saying it really does depend on the dog! We have two olde English bulldogs that we give this too! Our female does not have skin or seasonal allergies but she gets the most yeasty ears I’ve ever seen and this absolutely helps so much and she’s only been on it for about two weeks. Now our boy dog who is primarily white, had a allergy test and he’s allergic to everything including dog and cat dander lol we’ve been giving him this for about a month, and honestly haven’t seen much of a difference , still chewing on his feet like crazy . It sucks because it’s one of the only things he can have that doesn’t have something in it that’s he’s allergic too. None the less I believe it’s a great product and stand by it 100%, it just truly depends on your dogs. I definitely recommend giving it a try and allowing some time, do I think it’s an overnight cure? Absolutely not, but it could definitely help

### ⭐⭐⭐⭐⭐ Great product, but if your dog has had antibiotics, consider a gut biome test
*by L***T on 15 May 2026*

I love Four Leaf Rover products. They are always top notch and worked well for my dog, but the "allergies" were a constant battle, requiring four rounds of anti-fungals and anti-biotics over 18 months. I was told by one board certified dermatologist, a holistic vet, and two regular vets that the problem was allergies, and they all recommended Apoquel and Cytopoint. I suspected a leaky gut, so I gave my dog probiotics, kifer, bone broth, yogurt, etc. It wasn't enough. When I did a Gut Biome test, there was a problem where some bacteria was absent and some were overgrown. I gave my dog fecal transplant pills, and his hotspots and yeast disappeared, and now his hair is coming in thick and full. He even seems happier...waking up every morning with a big smile and spring in his step.
