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

On May 12, 2015 the dog developed dysphonia (dog lost his bark or squeaky bark). On May 13, 2015 the dog experienced a behavior change (dog had an unknown episode that could have been a seizure as the dog stiffened, became disoriented, and urinated during this event that lasted 30 seconds), so the owner removed the collar. On May 14, 2015 the dog experienced a behavior change (during a walk the dog became restless, collapsed, and started drooling, which all lasted 30 seconds). On May 15, 2015 the owner took the dog to the veterinarian where the dog was diagnosed with an arrhythmia (attending veterinarian suspects atrial fibrillation). The attending veterinarian then contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated systemic effects are not expected form dermal exposure to this agent. The APSS veterinarian finally stated intermittent signs and atrial fibrillation are not expected. The APSS veterinarian recommended supportive and symptomatic care, a diagnostic evaluation, bathing the dog, and calling back with questions.
