Hello, I am wondering how often and how much petromalt should be given on a regular basis. Due to too many raisins my boy Whiskey had an inflamed bowl and was in total misery. I thought he was going to die from it. It was suggested that I give petromalt, it definitely helped. He is all better and happy again. If anyone could help me with this question please reply. Thanks Peachy, Princess and Whiskey [Posted in FML issue 2497]
