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

On May 19, 2011 the owner noticed the dog was vomiting. On May 21, 2011 the dog's vomiting worsened and the owner rinsed the dog in water. On May 22, 2011 the dog began shaking severely and became lethargic. At an unknown date and time, the owner contacted a veterinarian, and on May 26, 2011 the owner took the dog to the veterinarian, where fluid therapy was provided on May 27, 2011. That day, the owner also stated the dog had azotemia, with elevated Blood Urea Nitrogen (BUN) and Creatitine levels, although no values were provided. Later on May 27, 2011 the owner contacted the Animal Product Safety Service to obtain help. The APSS veterinarian stated that topical use of synthetic pyrethroid-like flea preparations as per label directions was not expected to cause significant clinical signs. The APSS veterinarian stated that if the product is ingested via grooming, a taste reaction characterized by hypersalivation may occur, which can be resolved by feeding a taste treat to replace the bad taste. The APSS veterinarian recommended having the veterinarian call for information and calling back with questions.

The APSS veterinarian stated that the substance was not related to causing the clinical situation. On May 30, 2011 an APSS assistant called the owner to update the case. The owner stated that the vomiting had improved, but continued in small amounts, so she was giving smaller meals and providing Famotidine to the dog. The owner also stated that the shaking had ended and that the dog's lethargy was much worse. On June 8, 2011, an APSS veterinarian contacted the owner to update the case. The owner stated that the dog had died on June 4, 2011 and she did not want a necropsy.
