Anticoagulant rodenticides are widely used to control rodents. Anticoagulant rodenticides include two major groups (first and second generation).

The representatives of the first generation are: warfarin, coumatetralyl, chlorophacinone and representatives of the second generation are: difenacoum, brodifacoum, bromadiolone.

Causes of dog hallucinations

When the animal is poisoned, rodenticides cause the body to bleed due to the body’s inability to use its own depots of vitamin K.

Supplemental Vitamin K that is used in these types of situation is vitamin K1, known as Phytonadione, aman-made form of naturally occurring vitamin K.

By giving supplemental Vitamin K1 bleeding does not occur, or it occurs on a level that body can compensate. It takes up to 12 hours for new clotting factors to be made, and blood transfusion is suggested in the meantime.

"For rat poisoning, you need to use vitamin K1. It should be only available from your veterinarian, but sometimes they are available from a pharmacy. You will have to call around to find out. Make sure it is Vitamin K1, and not K3. ~Dr. Lee, veterinarian
