To be determined by Registrant

18. Severity classification (if there is more than 1 possible classification

Death

19. Provide supplemental information here

O - Unclassifiable/unassessable The reported application site mass may occur in sensitive animals after product application. It is usually mild and transient. Signs and time to onset are consistent. Further reported lymphoma and death are not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause such signs either. An overdose of 5 collars around the neck was investigated in adult cats and dogs for an 8 months period and in 10-week old kittens and - week old puppies for a 6 months period without causing serious signs. This is supported by the extremely low systemic exposure with imidacloprid and flumethrin, particularly during the first week after application and also thereafter. Time to onset is long. However, involved dog may have likely died due to underlying conditions. Previous exposure was well tolerated without any adverse event. Considering the product profile, product involvement is deemed unlikely, however due to limited information, (e.g. health status, medical history and necropsy report are unknown), case is considered as unassessable.
