19. Provide supplemental information here

B - Possible Though would not expect generalised skin disorders after topical application, reported itching, twitching and pacing may reflect paresthesia caused by permethrin. Whereas skin reaction at application site, e.g. pruritus or erythema may occur in sensitive animals, would not expect hot spot development directly related to product. However, likely linked to scratching at application site which caused sign by self-trauma, which secondarily became infected with bacteria. Considering consistent time to onset, a product connection is deemed to be possible.
