Tide laundry detergent
Fifty-one Ridglan beagles, ages 8-12 months, were force-fed four different laundry detergents. All of the dogs either died from the detergent or were intentionally killed 144 hours after ingestion.
An unknown number of male beagles were given Viagra and then given shocks with electrodes inserted into the center of their penises, despite the fact that Viagra was already in use in humans. All of the dogs were killed at the end of the study.
