What Dosage of Pepto-Bismol Do You Give to a 45-Pound Dog for Diarrhea?

For symptoms of diarrhea in a 45-pound canine, the recommended dose of Pepto Bismol is roughly 1/2 tablet, or 1.125 to 2.25 mL, advise pet experts at Quincy Paw Pals. While the medication is typically safe for all dogs, pet owners are advised to consult a veterinarian prior to use.

Possible side effects include darkening in tongue color, darkening of the stools, interference with readings of abdominal x-rays and inaccuracies in urine test results.

Additionally, Pepto Bismol is not suitable for canines with von Willebrand's disease or other bleeding problems and those pregnant or nursing young puppies, advise dog experts at VetInfo.com.
