(eg. description of the frequency and severity of the symptoms
1-17007982: A reporter called on 12/02/2008 to report the exposure of a dog to an anticoagulant rodenticide containing the active ingredient Brodifacoum. According to the reporter, the dog ingested an unknown amount of the product on 12/02/2008. The reporter had called the veterinarian prior to the report and was told that the dog should be fine. The dog was asymptomatic at the time of the report. The reporter was advised that the toxic dose based on her dog's weight is only 2.5 grams of bait. The mechanism of toxicity and signs of overexposure to the product were relayed to the reporter. The reporter was strongly encouraged to take her dog to the veterinarian for treatment with Vitamin K1. The reporter was advised that the treatment should be given daily for 21-30 days and a clotting time (PT test) should be done 48 hours following completion of treatment to ensure normal blood coagulation. On follow up on 12/04/2008, the reporter stated that the dog had developed signs of stiffness and vomiting (unknown how long following product ingestion). The dog was evaluated by a veterinarian on 12/03/2008. The dog was given a Vitamin K1 injection and the reporter was given two more to administer at home. The dog died at home on 12/03/2008. No further information was obtained.
Death
The time frame of symptom development is not consistent with ingestion of this anticoagulant rodenticide. Signs of toxicity secondary to product ingestion typically do not develop for 2-5 days following ingestion.
