OBJECTIVE: To describe the clinical course and novel biochemical findings in 3 dogs with amitraz toxicosis.
CASE SERIES SUMMARY: Three Labrador Retrievers developed acute onset obtundation to stupor after being in a rice field. On admittance to the hospital, they all displayed bradycardia, hyperglycemia, hyperlactatemia, respiratory acidosis, and metabolic alkalosis. All clinical signs resolved in 18-48 hours with supportive care. One dog represented with similar clinical signs and biochemical abnormalities 3 days after discharge following spending time in a different rice field owned by the same owner. Toxicological analysis of serum from all 3 dogs and vomitus from 1 dog returned positive for amitraz and one of its metabolites.
NEW OR UNIQUE INFORMATION PROVIDED: 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.
