Questions fréquentes
How much caffeine is toxic to dogs?
Mild symptoms appear at 20mg/kg of body weight. Severe toxicity occurs at 60mg/kg. The lethal dose (LD50) is approximately 140mg/kg. For a 20kg dog, this equals roughly 2,800mg of caffeine — about 28 cups of coffee. However, even small amounts (1-2 caffeine pills of 200mg each) can cause serious symptoms in small dogs.
What are the symptoms of caffeine poisoning in dogs?
Symptoms appear within 1-2 hours and include: restlessness, hyperactivity, vomiting, elevated heart rate, tremors, seizures, and collapse. Caffeine is absorbed rapidly and affects the central nervous system and cardiovascular system. Severe cases cause cardiac arrhythmias that can be fatal.
Should I induce vomiting if my dog ate caffeine?
Inducing vomiting may be recommended if ingestion occurred within 30 minutes and your dog is alert. However, caffeine is rapidly absorbed and can cause seizures — never induce vomiting if your dog shows any neurological symptoms. Call ASPCA Poison Control at (888) 426-4435 for guidance.
What is the treatment for caffeine poisoning in dogs?
Treatment includes: induced vomiting (if early), activated charcoal to reduce absorption, IV fluids for elimination, anti-arrhythmic medications for heart issues, anti-seizure medications, and temperature regulation. Hospitalization is typically required for 24-48 hours. Prognosis is good with early treatment.
