MiraLAX® is used as a laxative to treat constipation for dogs and cats. It contains polyethylene glycol 3350 which belongs to the class of drugs known as osmotic laxatives.
Polyethylene glycol works by creating an environment where water is retained in the stool
Polyethylene glycol 3350 should not be used in animals with gastrointestinal obstructions, rectal bleeding or a tear in the intestinal wall (bowel perforation), or toxic colitis. It is also not approved for breeding, nursing or lactating dogs or cats but is considered safe by many veterinarians.
