On 03-Jun-2017, the canine was examined by the attending veterinarian and an unknown number of ticks were found on the canine. The canine was diagnosed with tick paralysis, the collar was removed, and the canine was bathed. A new Seresto Large Dog collar (Flumethrin-Imidacloprid) was placed around its neck by the attending vet. The signs continued. On 21 Jun 2017, the signs worsened and the canine had trouble breathing. She was examined by the attending vet, had pale mucus membranes, a low white blood cell count, and was diagnosed with Ehrlichia Canis. The canine was hospitalized. Treatments were unknown. The canine died and no necropsy was performed.

N-Unlikely: In case of attachment of ticks these will be killed and fall off the host within 24 to 48 hours after infestation without having had a blood meal, as a rule. However, attachment of single ticks and even sucking of blood and thus transfer of tick borne diseases cannot be excluded while the collar is worn and simply reflects the labeled claim of efficacy that is not 100% against ticks especially when infestation pressure is high. Thus, infection with tick borne diseases despite wearing a collar can occur exceptionally and is consistent with the products claimed efficacy. This issue is addressed in the product information. Later reported signs, troubled breathing, pale mucous membrane and low white blood cell count are not expected with topical product application and may be associated with the diagnosed Ehrlichiosis. 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 serious signs either. Outcome is mostly associated with earlier reported signs caused due to tick paralysis and Ehrlichiosis . Though some information is not known (state of health, necropsy results) considering long time to onset and signs in chronology with diagnosed disease, a product relation is considered unlikely.
