(eg. description of the frequency and severity of the symptoms
On approximately 15 Nov 2009 the dog developed bloody diarrhea. The attending veterinarian stated the dog had pancreatitis from a recent food change. It is not known if any treatments were performed. The diarrhea resolved within 2 days. On approximately 01 Feb 2010 the dog had a subsequent product application of Advantage 20. On approximately 20 Feb 2010 the dog was seen by the attending veterinarian and diagnosed with uroliths. The dog was anesthetized with an unspecified anesthetic and the uroliths were surgically removed. On an unknown date in 2012, the dog had another surgery to remove more uroliths. On 01 Oct 2013, the dog had 1 tube of Advantage II Medium Dog (imidacloprid-pyriproxyfen)applied topically by the owner. In Aug 2014 the dog began having seizures. In Sept 2014, the dog developed a behavioral change. In Nov 2014, the dog began to inappropriately urinate and defecate. The dog was seen by the attending veterinarian. Bloodwork was performed and revealed elevated triglycerides. The dog was also diagnosed with a heart murmur. An unspecified dewormer, probiotic, and heart medication were prescribed. In April 2015, the dog developed watery diarrhea. In May 2015, the dog was found deceased. No necropsy was performed. The purpose of the call to Bayer Animal Health was not to report the death of this dog but to inquire about the use of Advantage II Medium Dog on another dog in the home. No more information is expected. Case is closed.
Death
Reported signs bloody diarrhea, pancreatitis and later diagnosed uroliths are not related with product as signs occurred before product application. Seizures and heart murmur are also not anticipated with topical use of product as not consistent with its pharmacological/toxicological product profile. Other reported signs, abnormal blood parameter, behavioural signs and watery diarrhea are unspecific and may have various other causes. Death not expected after product application, as inconsistent with pharmaco-toxicological product profile. Product has wide margin of safety. Oral LD50 in rat 642 mg/kg BW. 20-fold over dosage tolerated by dogs without showing any side effect. Dog involved in this case was geriatric, which may have caused death of the animal. Time to onset is exceptionally long (10 months after last application). The purpose of the call to Bayer Animal Health was not to report the death of this dog but to inquire about the use of Advantage II Medium Dog on another dog in the home. Although no necropsy was performed, overall, a product relation considered as unlikely.
