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

On November 2, 2017 the pet owner sought veterinary attention for fleas and lameness in a 7 year 10 month old, 61.4 kg, male neutered Newfoundland dog. The dog was not seen by the veterinarian and an appointment was made, and the pet owner was dispensed Advantage II for extra large dogs. The pet owner applied the Advantage II to the dogs skin at approximately 4 pm, and in less than 30 minutes the dog started shaking its head, became ataxic, and was foaming at the mouth. The dog was also gagging. The pet owner started to drive the dog to an urgent care facility and the dog died in transit. A post mortem examination is pending. The dog had a medical history of 'knee dysplasia' according to the pet owner.

19. Provide supplemental information here

N - Unlikely A behavioural response like reported shaking of head to the product sensation or to the product smell may occur. Gagging is an unspecific and may have many potential causes. Sign is not expected after topical product use and oral product uptake was not witnessed. Foaming at mouth is unspecific and may be associated with gagging. Ataxia is not expected with appropriate topical product use. Death is inconsistent with pharmaco-toxicological product profile and experience. Product has wide margin of safety. The oral LD50 in rat is 642 mg/kg BW. 20-fold overdosage tolerated by dogs without showing any side effect. Death here is likely associated with other unrelated causes. Even though time to onset is short, considering known safety profile of product and fatal outcome, a product involvement is unlikely.
