Overview of Psyllium (Metamucil®) for Canines and Felines

  • Psyllium is a bulk-forming laxative, commonly known by the brand name Metamucil® as well as many other genetic names, used to treat sand colic in horses, profuse watery diarrhea in cats and dogs, and other gastrointestinal disturbances.
  • It is derived from the ripe seeds of Plantago species. The seed coating is rich in hemicellulose mucilage, which absorbs water and swells inside the intestine.
  • Increased bulk of the intestinal contents is thought to promote peristalsis and slow intestinal transit. Psyllium is not absorbed from the intestine. It may take up 12 to 72 hours to take effect.
  • Psyllium is a non prescription drug but should be used under the guidance of a veterinarian.
