Amitraz toxicosis in 3 dogs after being in a rice field.

This is the first case series of dogs with confirmed amitraz toxicosis following an environmental exposure. Novel biochemical findings of hyperlactatemia, respiratory acidosis, and metabolic alkalosis were documented in all 3 dogs. Clinicians should be concerned for amitraz toxicosis when presented with an animal with the constellation of signs including decreased mental status, bradycardia, and hyperglycemia, particularly if relevant acid-base abnormalities are also detected.
