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


19. Provide supplemental information here

Digestive signs are unspecific and may have numerous other causes (e.g. gastrointestinal infection, dietary incompatibility and concomitant conditions). No oral product exposure. Reported systemic signs are unspecific, however in this case these are likely consequence of digestive disorders. Adipsia is not expected however, it is likely associate with anorexia. Serious signs like cardiac and respiratory arrest are not expected after topical application of the product. Death is not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause death either. No signs of anaphylaxis reported which would have occurred in close proximity to the collar application. Death was the consequence of serious signs (cardiac and respiratory arrest), moreover serious signs were observed after removal of collar. Considering the safety profile of the product, very long time to onset and though no necropsy was done sufficient information exists to rule out product involvement and relation remains unlikely.
