Plain-English summary

Six dogs in Oklahoma were brought to the vet after showing signs of serious illness due to paraquat poisoning, a highly toxic herbicide. Five of the dogs had lung and kidney damage consistent with this type of poisoning. The diagnosis was confirmed when a test on the vomit of one dog showed the presence of paraquat. Unfortunately, the outcome for these dogs varied, with some showing detectable levels of the toxin in their tissues. This incident highlights the dangers of herbicide exposure in pets.

Abstract

Paraquat is a restricted use herbicide which is extremely toxic to companion animals when ingested. This report details one incident of malicious poisoning involving 6 dogs. All dogs were from the same geographic area, and 5 had pulmonary and renal lesions consistent with paraquat toxicosis. Diagnosis was initiated by a modified dithionite spot test on vomitus from 1 dog. Subsequent tissue paraquat levels ranged from non-detectable to 1 ppm.
