(eg. description of the frequency and severity of the symptoms
On June 1, 2016 the dog developed pruritus. On June 8, 2016 the dog had a seizure. On June 9, 2016 the owner took the dog to the veterinarian for a diagnostic evalulation (everything within normal limits (WNL)). On June 10, 2016 the owner the bathed the dog (vinegar water) and the dog's pruritus ended. On October 19, 2016 the owner bathed the pet with a flea and tick shampoo. The dog then began having 4-5 seizures a day (sometimes the pet collapses and is limp and almost life-less, but is still breathing with a normal heart rate. Other times the pet has a standard seizure episode where the pet becomes rigid, paddling, vocal, and urinates on himself), so the owner took the dog back to the veterinarian for another diagnostic evalulation (everything still within normal limits (WNL)). On October 31, 2016 the owner the bathed the dog (vinegar water) and the daily seizures changed to become mild. On November 2, 2016 the owner contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated dogs tolerate pyrethroids well and no life threatening signs are expected. The APSS veterinarian also stated pyrethroids can cause a "pins and needles" sensation or hyperesthesia, resulting in reluctance to move, mild tremors, paw shaking, ear twitching or facial fasciculations. The APSS veterinarian additionally stated some dogs will develop erythema and pruritis as well. The APSS technician recommended having the veterinarian call for information.
Major
The APSS veterinarian stated that with the Zodiac spot on we may see dermal sensitivity and pruritis, but seizures are not typical and we would not expect persistent seizures. The APSS veterinarian stated that the cardiovascular disease was considered to have a medium likelihood of causing the clinical situation. On November 4, 2016 the attending veterinarian called the APSS. The APSS veterinarian reviewed the case with the attending veterinarian and the attending veterinarian stated the dog was started on phenobarbital earlier that morning. It is unknown if a veterinarian consulted before use of product on geriatric dog.
