Strychnine is a toxin (technically, an indole alkaloid) derived from Strychnos trees. It is rapidly absorbed from the stomach once eaten, causing dangerous effects on the nervous and muscular symptoms. In poisonings, seizure symptoms can occur within 15 minutes to 2 hours. Strychnine poisoning can be fatal to pets.
What are the symptoms of strychnine poisoning in dogs?
Strychnine Poisoning in Dogs
Limb rigidity.
Stiff muscles.
Severe spasms leading to arching of the head, neck and back in extreme hyperextension (opisthotonus)

How quickly does strychnine kill?
The usual fatal dose is 60–100 mg strychnine and is fatal after a period of 1–2 hours, though lethal doses vary depending on the individual.
Is strychnine still used in rat poison?
This plant is found in southern Asia (India, Sri Lanka, and East Indies) and Australia. In the past, strychnine was available in a pill form and was used to treat many human ailments. Today, strychnine is used primarily as a pesticide, particularly to kill rats.
Does strychnine break down in soil?
Strychnine bait is poorly soluble in water and strongly absorbs to soil particles. Environmental persistence is not long, and more than 90% disappears from soil within 40 days. Breakdown in soil is highly dependent on the presence and growth of particular microbial or fungal soil organisms.
How long can strychnine be detected?
Strychnine is rapidly absorbed from ingestion or inhalation, and can be absorbed through mucous membranes, but not through intact skin. It is rapidly detoxified by the liver, with a half-life of 10–16 hours. It is also rapidly excreted unchanged in the urine, and can be detected in urine within minutes of ingestion.
What does strychnine feel like?
Immediate signs and symptoms of strychnine exposure Apprehension or fear. Ability to be easily startled. Restlessness. Painful muscle spasms possibly leading to fever and to kidney and liver injury.

What causes a dog to be poisoned with strychnine?

Can a dog get strychnine from a rat?
Strychnine poisoning in dogs occurs when strychnine, a highly toxic compound used in many rat poisons, is ingested by dogs. Strychnine poisoning requires immediate medical attention, as death can occur without prompt treatment. Protect yourself and your pet.
Where does the most strychnine poisoning take place?
Grain-laced or pelleted commercial baits (usually <0.5%) are often dyed red or green. Malicious or accidental strychnine poisoning, although not very common in the USA, occurs mainly in small animals, especially dogs and occasionally cats, and rarely in livestock. Most poisonings occur when nontarget species consume commercial baits.
What kind of animals are affected by strychnine?
In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Its oral LD 50 in dogs, cattle, horses, and pigs is 0.5–1 mg/kg, and in cats is 2 mg/kg. Strychnine is considered a restricted-use pesticide. Its sale is forbidden in a number of states.

What’s the half life of strychnine in dogs?
The half life of strychnine is about 10 hours. Dogs are more susceptible than cats. LD50 in dogs is >0.2 mg/kg. In cats, the LD50 is >0.5 mg/kg. Ingestion of recently poisoned rodents and birds can result in relay toxicosis. Signs typically develop within 15 minutes to 2 hours after ingestion.
