    "Excellent Product, eliminates fleas/ticks!"

    I mix this in with the home made food I make for my dogs - 2 shih tzus and 1 chihuahua mix. They love it. The best thing it is provides a natural immunity to fleas and ticks (when fed regularly), so I haven't had to give them expensive, chemical-filled flea prevention meds in years - and they never have any fleas or ticks! This is a big deal, especially since we are in FL where there are lots of bugs. It also makes their coats so much softer and helps keeps the hot spots and itchy skin at bay. This will always be a regular purchase of mine, and I can't recommend it highly enough!

    "Love Bio-Coat!"

    We discovered this product years ago when we had a dog that was itchy and was losing the hair from the base of his tail to halfway up his back. The Bio-Coat did everything it promised to do. His coat all grew in again and he stopped his constant scratching. We have since used it on a couple of cats, with similar results.

    "Itch relief at last"

    This has helped my itchy dog tremendously! I was having to get him steroid shots at the doctor to give him some relief and he hasn't needed one since he's been on this. He will still occasionally itch, but not at all like he used to. He used to scratch himself raw. It has definitely improved. I recommended this to a friend and she reported the same results. The itching has decreased and no more need for shots.

    "Her hair is regrowing"

    My Italian Greyhound Patti Cake started to lose hair on her side and flank. She was diagnosed as hypothyroid and started on the meds but never regrew the hair. My vet was perplexed. Since I started to add Bio-Coat to her food, I can see hair starting to come back and I hope she will get all of her hair back - they don't have much to begin with. :).

    "Looking for a Great Biotin Supplement Product?"

    Our Golden has skin allergies, and we give him this Biotin product as a vitamin supplement since he is always on prescription medicine for either his allergies or skin infections. He loves it! In fact, our perfectly healthy Miniature Schnauzer loves it, too!

    "Working Wonders"

    We adopted a senior yellow lab 2 years ago who was itchy. We tried so many products both oral and topical, changed dog foods, etc. About 3 months ago, I started giving her Bio-Coat, her coat got thicker and even the worn spots on her elbows grew hair! Her coat looks healthy and she doesn't constantly itch. Her coat looks so good, I started giving it to my senior chow/shepherd who looks stunning now!

    "The answer I was looking for"

    After years of my dog's frustrating struggle with allergic flea dermatitis that lead to constantly chewing, scratching, flaking, bleeding I finally found BioCoat. I had tried every kind of diet, from raw to limited ingredient, using Frontline and Advantage consistently, adding healthy oils to her food, and nothing was working. My poor dog was in a constant state of worry and discomfort. I finally found BioCoat in another desperate search and bought some. I am not exaggerating when I say that this product CURED my dog. I also gave it to my cat to had a similar problem with mellitus dermatitis. Same results! EVERYONE needs to try this whose animals are having these problems.

    "Dog owners need this"

    "This product I can not live without. I have several dogs, large and small, in my house. This product reduces the amount of hair that is shed. With the exeption of the usual ""shedding"" this product will largely reduce the shedding. My dogs have no problems eating it and their coats are soft and shiney. A no can do without product."

    "A Must have for dog/cat owners"

    I've been using this product for the past 6 years and I must say that there is no other product that would be as effective as BioCoat. My dogs and cats always had dry skin. I went to many vets and they could do nothing about it, but once I put them on BioCoat the problem of dry itchy skin just went away. They have beautiful coats and don't scratch like crazy. Although this product is hard to find (mostly online) I truly recommend it.
