My Clubber, who is just over a year and a half now, has always suffered from loose stools. He frequently has to have his anal glands expressed by the vet and takes to scooting on the ground a lot. We've tried multiple food changes (to ones with a bit more fiber) to no avail. I read on this board a while back that you can add Metamucil to their food - is that true? If so, how much should I add and how often? Clubber weighs almost 60 pounds. Does it matter which flavor metamucil? Would wheat germ also work? Any other ideas?
