Superwarfarins remain in the body for a prolonged time and it takes approximately 30 days of continuous vitamin K1 for dogs to be considered safe. Vitamin K1, a natural blood coagulant, works by reversing the anticoagulant effect of rodenticides. The difference is that these compounds are long-acting and may continuously thin the blood for over three to five days, eventually leading to death. These compounds work similarly to blood thinner medication that stops blood clots in heart patients. Rat poisons contain potent anticoagulants called superwarfarins.

Should your dog mistakenly ingest a poison of this type, vitamin K1 is the only antidote. They kill rodents by preventing their blood from clotting, causing internal bleeding. Long-acting anticoagulants, LAACs, are common poisons formulated for rats and mice.

How or why would your dog ingest an anticoagulant poison? Surprisingly, this happens often. However, a lack of vitamin K can cause blood hemolysis and anemia. Vitamin K1 can be used for your dog in a few circumstances, specifically if they have ingested certain poisons.īetween the foods we eat and the natural vitamins in the stomach, there’s a healthy supply of vitamin K, so there is little need for food supplements.

Vitamin K1, also known as phytonadione, is the dietary form of vitamin K found in plants and most food supplements. This vitamin is required for healthy blood function in all animals, including our pets. Vitamin K is a fat-soluble vitamin necessary for normal blood coagulation and control of calcium deposits in bones and tissues.
