I was one of the lucky ones… I used this on my dogs( 1 large pit bull and a pit puppy) and within a day my larger pit was literally loosing the skin from the side of his face. The puppy was fine and I’m thinking that’s was only because his coat is so thick it never made it all the way to his skin. Cato the larger one on the other hand has skin issues so his fur is much thinner. I will never ever use this again. It cost me tons of money to get him back to normal. The side of his face looked like it was just disintegrating over night. He was sick. It was horrible. I thank god everyday I just had to deal with that and I didn’t loose both my babies.
