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

On October 31, 2017 the dog developed dandruff. On November 1, 2017 the dog developed ataxia, anorexia, a head tilt, vocalization, agitation, and polydipsia. The owner then gave the dog a bath (with medicated dandruff shampoo, gave two baths, symptoms continued). On November 4, 2017 the owner took the dog to the regular veterinarian who had to sedate the dog because he was very agitated. The regular veterinarian gave an antihistamine (Benadryl, for two weeks) and sent the owner home with Vanectyl P tablets (for two weeks). Later in the afternoon, the owner contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated that mild dermal paresthesia may be seen with associated behavioral responses (hiding, whining, rolling, etc). The APSS veterinarian also stated that the wet area after application can accumulate dust, appearing like dandruff, unsure if that is the case in this dog. Finally, the APSS veterinarian stated that some of these signs would not be expected from this product. The APSS assistant recommended the owner monitor at home, give the dog a bath (with Dawn dish soap), apply vitamin E oil to the application site, apply a cold compress, and to call back with questions.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. The APSS veterinarian also stated that head tilting would not be expected and signs would not be expected to be seen a week later. On November 6, 2017 the owner called back to update the case. The owner stated that the dog is still experiencing symptoms but the dandruff, ataxia, head tilt, vocalization, and agitation have become more mild. The APSS veterinarian stated that given the time frame, signs should have resolved by now.
