Immediately post application, the dog exhibited a behavior change and generalized pruritus. On approximately 15-Oct-2015, the dog exhibited anorexia, adipsia, and malaise. On approximately 20-Oct-2015, the dog was examined by a veterinarian and had full anal sacs; which were expressed. On 22-Oct-2015, the dog couldn't walk. The collar was removed. The dog was examined by a veterinarian and had a blood profile performed. The kidney and pancreatic function tests were abnormally elevated. The dog was diagnosed with renal disease. The dog was administered subcutaneous fluids and furosemide injectable. The dog weighed 16 pounds. On 23-Oct-2015 the dog was able to walk again.

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


19. Provide supplemental information here

Reported behavioural change is an unspecific sign and may have various other causes in a dog. Generalized pruritus is not typically seen with topical product administration. If any, skin reaction would be localized at the application site. Time to onset is very short for these reported signs. Further reported anorexia, adipsia, malaise and walking difficulty are unspecific signs and not expected after collar application and time to onset of signs is too long with more than two weeks. Signs might be linked to the further diagnosed renal disease. Anal sac disorder is not expected to be product related and is likely only a concomitant finding. Reported elevation in kidney and pancreatic function tests, weight loss and especially death are not expected after product application as they are inconsistent with the pharmaco-toxicological product profile. An oral exposure to the collar is not expected to cause death either. Moreover, these signs were reported after collar removal. Death likely consequence of renal disease. Finally, even though necropsy was not performed and time to onset for initial signs is short, considering all available information, chronology and long time to onset for further reported signs, the products pharmaco-toxicological profile and the fact that an alternative cause was identified, a product relation is deemed to be unlikely.
