Plain-English summary
A 5-year-old female spayed Pit Bull Terrier was found unresponsive after being left unsupervised for about 15-20 minutes. The owner noticed the dog having what looked like a seizure and rushed her to an emergency vet. Upon arrival, the dog showed signs of rapid heart rate, fast breathing, and severe tremors. Despite intensive treatment, she went into respiratory and cardiac arrest and sadly passed away about 28 hours later. A postmortem examination revealed that she had been poisoned by bifenthrin, a type of insecticide.

Abstract
A case of canine intoxication and fatality with the pyrethroid insecticide bifenthrin is described. A 5-year-old female spayed Pit Bull Terrier was off leash and unsupervised at home for 15-20 min prior to discovery by her owner. The patient was in lateral recumbency, having what the owner described as a seizure. The patient was transported to an emergency veterinary hospital where she presented with tachycardia, tachypnea and intractable tremors/seizures. Despite aggressive medical intervention, the patient went into respiratory and cardiac arrest and died at 28 h after presentation. A postmortem liver sample screened positive for bifenthrin by gas chromatography-mass spectrometry (GC-MS). During the screening procedure, four additional bifenthrin-metabolic products were also observed. Concentrations for bifenthrin were determined for fat, kidney, liver and urine by GC-MS-MS. This is the first reported case of a canine fatality resulting from bifenthrin.
