A natural answer to allergy medication.
I learned of this supplement from Layla the Boxer's mom. My Cairn has seasonal skin allergies that cause him to scratch and lick incessantly. He is a very picky eater and this product is easy to sprinkle over his food. It must not have much taste, or a disgusting one, because he eats without hesitation. It is very effective and usually calms his scratching/licking in a couple days and ends it in about a week. I only use the product as needed and have ordered it twice in as many years (I think).. I feel it is a good value and keeps him off prescription or OTC allergy medication.

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.

Good, but not great.
We'll see how this works once the weather warms up but for now, I do think this took the edge off and kept me from having to give my dog daily Apoquel during this past winter. I'm not sure that he loves the taste (it's very green smelling) but if I mix it in with a topper for his kibble he eats fine. My other dog with MCT's wasn't affected by this (good or bad) but since it didn't seem to make a difference for her, I stopped adding it to her food. It certainly lasts longer when only given to one dog! Pricey but overall not a bad product to trial and see if it works for yours.

Noticeable Improvement in Coat and Skin
This supplement has made a big difference for my dog’s skin and coat. After a few weeks of use, his fur looks shinier and his itching has reduced a lot. The ingredients seem high quality, and my dog eats it easily with his regular food. I like that it includes quercetin, which helps with allergies and inflammation.

Not helping
My dog keeps itching, seems to be more than before and now he has diarrea. It's been 3 weeks since I've been giving it to him and nothing has changed, it got worst.

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

Don’t subscribe until you try it out first
My dog was so itchy, so I did some research and wanted to try Quercetin which is in this Harmony supplement. My dog had a reaction to something in the supplement and her itchy patches got worse. Her paws and around her muzzle got bright pink from her being itchy and her reaction. As soon as we thought it was the supplement, I went to cancel the order, but it was one day too late. It can’t be returned now. What a waste of money for us-not happy about that. They should make this product eligible for returns, as it has not been opened. Don’t do what I did.

Mixed review
Did nothing for my German shepherd’s allergies but was helpful to my friends, Rhodesian ridge back’s allergies.
