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

Approximately 3 hours post application, the dog had respiratory distress, ataxia, polydipsia, and vomited once.Approximately 7 hours post application, the dog died, CPR was performed with no positive results.On approximately 03-Nov-2014, the necropsy revealed a subcutanous and intramuscular bruise at the 8 and 9 intercostal spaces (ecchymosis), hemoabdomen (hemorrhage NOS) secondary to uterian stump hemorrhage ,diaphragmatic hemorrhage and hemothorax. The preliminary cause of death is fatal internal hemorrhage. Microscopic tissue evaluation revealed cardiac hypoxia and segmental hypertrophic arteriosclerosis of intramural coronary arteries. Cause of death was determined to be severe, subacute, abdominal hemorrhage originating from urterine arteries

To be determined by Registrant

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


19. Provide supplemental information here

Vomiting and ataxia more expected after oral product exposure than after topical product application. Potential oral uptake is not witnessed. Respiratory distress and polydipsia are not expected either. Signs may have many potential other causes. Death with reported necropsy findings is unexpected and rather inconsistent with pharmacotoxicological product profile. The dog was operated for ovariohysterectomy 9 days prior to application of product and thus as reported, death was due to severe, subacute, abdominal hemorrhage originating from urterine arteries. Though consistent time to onset, considering all aspects, a product connection remains unlikely.
