our Tibetan Terrier is 13 years old and had his second stroke with consciousness disorders and lameness of the feet. Even after a week Karsivan he was doing much better again. After three months, nothing more can be seen from the disabilities. He jumps like a puppy around, playing with others and is glad of his life. A wonderful agent that I recommend any old dog for daily intake. Dog and owner (in) will be pleased at the effect.
