(eg. description of the frequency and severity of the symptoms

On November 18, 2009 the owner noticed a mild rash on the dog's groin and took her to the veterinarian, who prescribed an antibiotic and an antihistamine. The rash started clearing up. On December 2, 2009 the owners took her to the veterinarian, where she received supportive care with fluids and medications. On December 3, 2009 the APSS veterinarian recommended monitoring the dog at home, discontinuing the product usage, and call back with questions. A follow up was not set up as signs were expected to be mild and self limiting.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. On December 17, 2009 the owner called the APSS to update the case. At that time, the owner informed APSS of the repeated exposure to the Biospot agent. The owners stated on December 5, 2009 the neurological signs became worse so they took her back into the clinic, where she stayed overnight. On December 6, 2009 she suddenly had a seizure, stopped breathing sometime in the afternoon, and could not be revived. A necropsy was completed by another facility and some tissue fluid samples had been saved, but the dog had been cremated. The APSS veterinarian stated canine patients are less sensitive to the permethrin and do not develop central nervous signs from appropriate use. On December 21, 2009 an APSS assistant contacted the laboratory who had done a general necropsy, stains, and blocks of muscle tissue but recommended further testing as the initial testing was inconclusive. The necropsy results showed no significant gross pathologic alternations except for minimally rounded heart. Inflammatory diseases and infection causes were not recognized. Exposure to mycotoxins and other toxins were considered as a likely cause.
