On 02-Jun-2021, a 10 year old, approximately 8 pound, neutered, male, Crossbred dog, in unknown condition, with concomitant medical conditions of cardiac disease, liver disease, tracheal collapse and suspected Cushings disease, was administered 1 collar of Hartz UltraGuard Flea and Tick Collar for Dogs (non-specific) (Tetrachlorvinphos (Rabon)) via the topical route by the animal owner. The dog also received an unknown dose of furosemide via the oral route that was prescribed previously. On 03-Jun-2021, the dog developed seizures and may have gone into cardiac arrest. The animal owner performed cardiopulmonary resuscitation on the dog, removed the collar, and bathed the dog with an unknown amount of unspecified human shampoo. On 04-Jun-2021, the dog was brought to the emergency veterinary facility for evaluation. Upon presentation, the dog exhibited head tilt and circling to the right, strabismus to the right, in the right eye only, went limp, was unable to stand, had two seizures, had slightly elevated liver enzymes and was not mentally appropriate. The dog was admitted to the intensive care unit and was placed on oxygen therapy. The seizures and muscle twitching resolved at a unspecified time after the administration of 3 doses of atropine, and unspecified doses of midazolam, levetiracetam, methocarbamol, and phenobarbital. The veterinarian also noted apparent respiratory concerns and changes to the right lung (pulmonary edema), possibly related to cardiopulmonary resuscitation efforts at home. The dog was also administered butorphanol due to increased respiratory effort. On approximately 07-Jun-2021, the dog had elevated renal values, circling, and dyspnea continued, but showed improvement with the other clinical signs. On 14-Jun-2021, the clinical signs returned and the dog developed hypersalivation, experienced intermittent focal seizures and non-specific neurological signs. On 15-Jun-2021, the dog died. The emergency veterinarian suspected the dog had a brain tumor and that the clinical signs were not likely related to the product. No further information was received in this case.

Assessment: This product contains tetrachlorvinphos, an organophosphate insecticide with a good safety margin in dogs. Even if product residue were ingested after application, only mild GI upset would be expected. The severe and progressive signs reported, even after product removal and bathing, are not consistent with the toxicological profile of the product. The treating veterinarian suspected the dog had a brain tumor and also did not think the dog's signs were consistent with organophosphate toxicosis. The information contained in this report is based on self-reported statements provided to the registrant during telephone interview(s). These self-reported descriptions of an incident have not been independently verified to be factually correct or complete descriptions of the incident. For that reason, information contained in this report does not and cannot form the basis for a determination of whether the reported clinical effects are causally related to exposure to the product identified in the telephone interviews.
