I started using this yeast infection treatment for my eighty pound dog who has ongoing allergies that cause itching, paw biting, and redness. The salmon flavor made it easy to add to his food and he accepted it without any hesitation.I cannot make medical claims, but I can describe my own experience. After using it as directed, his ears and paws began to look a little calmer and he seemed less focused on scratching. He has very sensitive skin, so I am careful with anything new, and I appreciate that this formula is gentle and made with natural ingredients. It did not cause any stomach issues or bad reaction for him.Every pet is different, but this has been a positive addition to his routine and has helped provide some comfort for his skin.
