(eg. description of the frequency and severity of the symptoms
On July 22, 2013 the owner noticed that the dog had hind limb paralysis. A short time later that evening the owner took the dog to an emergency veterinary clinic, where the dog was monitored overnight and various unspecified testing was performed. The next morning, July 23, 2013, the dog was transferred to her regular veterinarian, where she was observed to have a severe flea infestation. On the morning of July 24, 2013 the owner's regular veterinarian referred the owner to a specialty clinic, where a tick profile was done. That morning the owner took the dog home, monitored the dog, and provided unspecified supportive care to the dog. On July 26, 2013 the owner noticed that the dog was anorexic and not improving, so she took her back to her regular veterinarian; the regular veterinarian gave the dog a Corticosteroid injection, which was not effective. The owner continued to monitor the dog and provide supportive care at home after returning from the regular veterinary clinic. On July 28, 2013 the owner observed that the dog died. On January 6, 2014 the owner contacted the Animal Product Safety Service (APSS) to obtain help. The APSS veterinarian stated that Etofenprox is classified as both a pyrethroid-like insecticide and a non-ester pyrethroid; it is safe to use on cats and dogs, and does not result in tremors or seizure activity that can be seen from other pyrethroids because it is structurally different. The APSS veterinarian said that oral exposures often result in hypersalivation, nausea, and possibly hiding because of the taste. The APSS veterinarian stated that hind limb weakness and death are not expected. A necropsy was not available to determine the dog's cause of death.
Death
The APSS veterinarian stated that the substance was not considered to be related to causing the clinical situation.
