Common signs of poisoning include signs of internal bleeding: lethargy, exercise intolerance, coughing, difficulty breathing (due to bleeding into the lungs), weakness, and pale gums. However, if the pet has been chronically exposed to the product, the onset of clinical signs may be sooner. When dogs or cats ingest LAACs, it typically takes 3-5 days before signs of poisoning are visible. Long-acting anticoagulants work similarly to the “blood thinner” medications that people take (e.g., warfarin or Coumadin®). This type of poison prevents the blood from clotting, resulting in internal bleeding. Long-acting anticoagulants (LAACs) are the most common and well known type of mouse and rat poisons.
