Shake well before use. Use 3 times a week or as directed by your veterinarian. Apply to a brushed, dry coat. Gently massage 1 or 2 pump(s) onto the problem area of the skin until the mousse reaches the skin. Repeat this action until the body is covered, avoiding the eyes and mouth. Do not rinse, let air dry. Re-brush for a shiny coat.

Soothing Skincare for Pets

DOUXO S3 features Ophytrium, a purified natural ingredient that acts in three key ways to encourage healthy and comfortable skin. Ophytrium helps support supple and hydrated skin to reinforce the skin’s physical barrier, and it helps nurture healthy microbial skin flora, too. It also helps soothe red, itchy and irritated skin.

    It's Amazing Stuff

    By SmokingGecko on Jun 26, 2021

    My vet recommended this and supplied me with a bottle of mousse to help clear up a bacterial and yeast infection my 9 year old American Eskimo mix was suffering with due to scratching from severe pollen allergies. She developed dermatitis along on her belly, her spine and inside the ear flaps. This product relieved itching and cleared up the inflamed skin. It also was used to treat swelling from an anal gland infection. She's doing much better, but as she still gets minor outbreaks, I want to have this mousse on hand.

    It leaked out, but it's a good product.

    By WrinksJae2 on Jun 8, 2021

    I love this mousse and it did wonders for my dog's coat after only a few applications, however a few was all I got because it leaked all out of the bottle. I noticed when it arrived the it wasn't completely full but chalked it up to the company not filling the bottle, but now I believe it was leaking before it even left to be shipped to me. It is very disappointing how faulty the new bottle design is now. I definitely did not get my monies worth. If you happen to get a bottle that doesn't leak; it's worth it.

    Very good for his allergies

    By JoVincent on Jul 21, 2021

    My boy has bas seasonal and skin allergies and this works very well for him. No smell and quickly soaks in to the skin. I like that it's a mousse and has an easy applicator. The new look of the container is very appealing as well. Thank you.

    Great for itchy elbows

    By Rebbekkah on Jun 14, 2021

    My German Shepherd kept getting itchy weepy low grade infections on his elbows. He works as a service dog every day and he does not always get a pad to lay on when about the city. My vet recommended this foaming product. My dog comes up and volunteers to have me apply to his elbows every night - no more elbow problems. It’s pricy but just takes 2 pumps per elbow and a bottle lasts a long time. Definitely worth the price.

    Our sheperd battles with itchy skin, and had itched himself to the point of soars, worked great to clear him up. Product has nice smell as well.

    It all leaked out everywhere, be careful with the pump.

    By AmberJ on Jun 2, 2021

    I can’t review if it works, but can only review that the orange pump does not stay screwed on securely. It got tipped over and spilled out everywhere. Our vet recommended this mousse for our sensitive dog, so I may rebuy it, even though it’s pricey and duct tape the pump on to the bottle so that it doesn’t leak out again.

    Very soothing and wasy to use. Non-irritating. Dogs don't lick it off. Real protection against spores and funghi on the ground in dog parks.

    Ichthyosis in my American bulldog

    By Pearl on May 5, 2021

    My dog is prone to yeast and bacterial infection all over but especially paws. Her dermatologist recommended this new product. I already use the douoxx shampoo 2 xs a week and then the Antifungal shampoo every night on her paws and apply this Mousse. Everything helps. I just wish it was cheaper since I have to use so often for the rest of her life.
