My parent's dog had horrible kidney stones and a urinary tract infection. He could not hold his urine sometimes and other times he could not release it. He was in a lot of pain. The vet reccomended surgery. My mom was reluctant because she believes in natural cures and the fact that there is a 40% chance of it repeating in a year. She put him on a special diet and it didn't work. After two days of putting him on the Apple Cider Vinegar, he appears to be cured! They put a little in his drinking water and a few drops in his food. It worked like a wonder drug! He is happy and energetic again and is no longer having accidents or in pain. He is back to his old self. Highly Recomended!
