19. Provide supplemental information here

The reported application site disorders may occur in sensitive animals after product application. They are usually mild and transient. Signs consistent. Long time to onset. Unclear if correct fit of collar was checked periodically as recommended in the product information and thus development of signs not noticed. Skin disorders not expected on other than the application site is not typically seen with topical product administration. Time to onset long. Dog's medical history of skin disorders more likely cause the sign observed. Death is not expected following appropriate topical product application as inconsistent with products pharmacological profile. Time to onset long: death occurred several days after product has been withdrawn. Other products given concomitantly. Although no necropsy performed, product involvement is not likely, however due to limited information case is considered unassessable.
