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

On September 17, 2018, the dog developed lethargy. On the morning of September 18, 2018, the dog developed anorexia and his lethargy became severe. That late afternoon, the owner took the dog to the regular veterinarian for evaluation. The regular veterinarian heavily saturated the dog with the product to treat for fleas. The regular veterinarian then did a diagnostic evaluation (blood work and fecal). The dog was positive for heart worm disease. That night, the dog developed tremors (the owner thought initially that the dog was asleep and just moving his legs while dreaming; the owner is not sure if it was tremors or seizures). An hour later on September 18, 2018, the dog passed away. On September 19, 2018, the owner submitted the dog's body for a necropsy. Upon necropsy, 4 heart worms were found. Per the owner, no definitive cause of death was identified and the dog was cremated. The remaining samples were sent to another diagnostic lab for secondary testing and evaluation for etofenprox. No tissue levels were found in the liver (other organs were not available for testing at this point). On November 26, 2018, the owner contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated that etofenprox is in the pyrethroid family, although it is structurally different than other pyrethroids and that this insecticide is safe to use on dogs as a topical agent to treat fleas. The APSS veterinarian continued by stating that trembling and tremors can also be seen, whereas seizure activity rarely occurs. The APSS veterinarian discussed with the owner that levels of etofenprox are expected to peak within 3 hours of application and that there is systemic absorption and redistribution with some storage in the liver. The APSS veterinarian also stated that with heart worm disease, there is turbulent blood flow and blood vessels grow abnormally, so a possible clot dislodgement contributing to death after the stressful event such as a veterinary visit could have been seen. The owner expressed concern about the organ samples not being from her dog and wanted to know where she could have DNA testing done. The APSS veterinarian recommended the owner reach out to MMI Genomics or possibly the University of Missouri.
