The formula works synergistically to cover all the bases of urinary health and bladder function, including organic cranberry extract and d-mannose―a naturally-occurring molecule found in birch and beech trees―to support healthy urinary tract flora, plus glucosamine and MSM to nourish the bladder lining, soothing corn silk and marshmallow root, and other specially-selected herbs and nutrients. Your pal will love the natural beef liver flavor, on its own or mixed into his favorite food, and is made in the USA with no fillers.

    UTI support for cat who had PU surgery.

    By TinkleTonicWrks on Mar 19, 2020

    I'm not sure if it works yet but I add to my cat's wet food and he eats it as if he doesn't taste it. He had PU surgery for a stress induced blockage, and gets UTI's regularly. I needed something preventative. The key to this product is: D-Mannose. I usually trust Mercola products. So far, so good.

    Did not help my dog

    By Robert on Jul 31, 2019

    It did not help my dog , but to be fair I've tried other products plus everything the vet gave her , and nothing has made any difference . This product did actually seem to make it slightly worse , but it may just not be effective for her condition. As always delivery was super fast. I have resigned to the fact that she has to be confined at night and when we are not home. So I purchased a exercise pen from Chewy and pee pee pads

    Bladder supplement

    By Lily on Jun 29, 2019

    I have been using this supplement for about six months in my dog’s food. It was highly recommended by a holistic vet in our area. To date, her bladder issues have not reoccurred.

    ShihTzu are know to have bladder infection or kidney stones. This product helped eliminate the need for surgery and removed crystals from my 9 year old baby girl’s urine. Will use this and other Dr Mercola products for life.

    Helped my dog with incontinence!

    By Renee on Apr 17, 2019

    My poor baby was leaking all over the place and having accidents in the house. This stuff is absolutely amazing. I’m very glad I found it. I couldn’t keep her on the recommended medicine due to the side effects.

    Did not work

    By PamNC on Feb 24, 2019

    I have an 10 year old spayed female Shetland Sheepdog. She has been having intermittent leaking problems while sleeping during the day. This medication did nothing to help with this problem - not even a little bit. It was a complete waste of money.
