Canine rodenticide poisoning is a serious issue, especially when dogs ingest baits containing anticoagulants. These rat poisons are quickly absorbed into the body, but symptoms usually do not appear until 2 to 5 days after ingestion. This delay occurs due to the internal and external bleeding caused by the anticoagulant’s effects.
Symptoms of Rodenticide Poisoning
The early signs of rodenticide poisoning in dogs are often subtle. The animal may become weaker and lose its appetite. Depending on the location of the bleeding, visible signs such as nosebleeds, bleeding from the mouth, or blood in the stool may appear. Other symptoms include bruising under the skin and difficulty breathing. In some cases, internal hemorrhages can lead to sudden death.
Rapid Treatment: The Key to Survival
When a dog is brought to a veterinary clinic, blood clotting tests are performed to confirm poisoning. If the animal is seen within the first few hours of ingestion, immediate intervention is possible. Medications can be given to induce vomiting and limit toxin absorption. However, the primary treatment is Vitamin K1. The duration of this treatment depends on the type of anticoagulant ingested, which is why having the rodenticide packaging is crucial. It helps the veterinarian determine the appropriate course of action.
When Symptoms Are Already Present: A More Complex Approach
If symptoms of canine rodenticide poisoning have already developed, inducing vomiting is not recommended, as it could worsen the bleeding. Instead, other measures must be taken, such as administering oxygen and possibly draining fluid from the chest cavity. Blood transfusions may also be required. Vitamin K1 remains essential, but it takes 6 to 12 hours for its effects to be noticeable.

Prognosis: Acting Fast to Save Your Dog
The prognosis is generally excellent if treatment is started before symptoms appear. If clinical signs are already present, the prognosis becomes more uncertain. However, with prompt treatment, the chances of recovery remain high.
