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

On 04Mar2016, the dog became inappetent. The dog was examined by the veterinarian and was administered an unknown dose of dexamethasone sodium phosphate by injection. On 07Mar2016, the inappetence resolved. The owner removed the Seresto collar. On 08Mar2016, the dog became lethargic. On 09Mar2016, the inappetence recurred and the dog exhibited tachycardia, and vocalization. The dog was examined by the veterinarian and was exhibiting seizures, trembling, and decreased motor function. The cardiac murmur had increased in severity. Prior to any diagnostics, the dog went into cardiac arrest and died. No necropsy was performed. The reason for the initial phone call was to discuss the use of the product and not to report the death of the patient. No more information is expected and the case is closed.

To be determined by Registrant

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


19. Provide supplemental information here

Inappetence is unspecific and may have numerous causes. Time to onset is short, but several vaccines applied as well. All further reported other signs occurred two days after removal of collar thus not product related. Time to onset is long. The reason for the initial phone call was to discuss the use of the product and not to report the death of the patient. Animal has concomitant history of cardiac murmur which is suggestive of other unrelated and undiagnosed causes. Considering all clinical signs and chronology, a product relation is unlikely.
