Methamphetamine poisoning in three Oklahoma dogs.

Methamphetamine is an amphetamine derivative and a category II controlled substance. It is uncommonly prescribed by physicians, but is more often used illegally as a stimulant. In this case study, 3 dogs were believed maliciously poisoned. Methamphetamine was detected in the stomach contents of 1 dog. One died and 2 recovered after gastrointestinal decontamination and supportive care. The recommended treatment protocol of methamphetamine toxicosis should also include urine acidification and alpha-adrenergic blocking agents.
