How does rat poison work on dogs, and how long does it take to take effect? - briefly
Rat poison works by preventing blood clotting in dogs, leading to internal bleeding. The time it takes to take effect varies depending on the type of poison but can range from hours to days.

Rat poison designed for rodents can have severe or even fatal consequences when ingested by dogs due to the active ingredients typically used in these products. The most common types of rat poisons are anticoagulants, which work by preventing blood clotting, and bromethalin, a neurotoxin that affects the central nervous system.
Anticoagulant rat poisons contain substances such as brodifacoum, bromadiolone, or difenacoum, which inhibit the recycling of vitamin K in the body. Vitamin K is essential for blood clotting; without it, the blood loses its ability to coagulate, leading to internal bleeding and hemorrhaging. In dogs, ingestion of anticoagulant poisons can result in symptoms such as lethargy, pale gums, difficulty breathing, and excessive bruising or bleeding from any part of the body. The onset of these symptoms typically occurs within 24 to 72 hours after ingestion, but it may take up to five days for signs to become apparent due to the slow accumulation of the poison in the body.
Bromethalin is another type of rat poison that acts differently from anticoagulants. It disrupts the mitochondria within cells, leading to a breakdown in energy production and causing swelling of the brain and spinal cord. Symptoms of bromethalin toxicity in dogs include seizures, tremors, paralysis, and eventually coma or death. The onset of symptoms is usually rapid, appearing within 2 to 12 hours after ingestion. However, delayed symptoms can occur up to several days later due to the accumulation of the toxin in the central nervous system.
If a dog ingests rat poison, prompt veterinary intervention is crucial. Treatment options vary depending on the type and amount of poison consumed. For anticoagulant poisons, vitamin K1 supplementation may be administered to reverse the effects, while for bromethalin toxicity, supportive care such as intravenous fluids, anti-seizure medications, and oxygen therapy may be necessary to manage symptoms until the body can eliminate the toxin.
In conclusion, rat poison poses a significant threat to dogs due to its potent active ingredients that disrupt vital physiological processes. Understanding the mechanisms of these poisons and recognizing the signs of toxicity is essential for prompt and effective treatment. Preventing access to rat poison by keeping it out of reach of pets is the best approach to safeguarding canine health.
