Treatment

If your dog is suffering from spontaneous bleeding caused by anticoagulants, the treatment will involve administering fresh whole blood, or frozen plasma, in an amount determined by the rate and volume of the animal's blood loss. Vitamin K, which is necessary for normal blood clotting, will be used specifically as an antidote, and will be given by subcutaneous (under the skin) injections, with repeated doses as necessary -- by injection or even orally -- until the blood clotting time returns to normal.

Do not induce vomiting unless you have been advised to do so by your veterinarian. Some poisons can cause more harm coming back through the esophagus than they did going down.

Living and Management

If your dog consumes a mild cumulative form of an anticoagulant, your dog may recover in a week, but if it was the lethal single dose anticoagulant, it may take up to a month.

Prevention

Anticoagulant poisoning can be prevented by keeping all poisons out of the reach of your pets. All other chemicals, drugs, and medications (especially blood thinning drugs) should also be kept out of your dog's reach -- ideally inside of a cabinet.
