その背後の科学
チョコレートにはテオブロミンとカフェインが含まれており、どちらもメチルキサンチンであり、犬は人間よりもはるかに遅く代謝します。人間はテオブロミンを2-3時間で排除しますが、犬は17.5時間以上かかります。これにより、体内に有毒なレベルが蓄積します。テオブロミンは中枢神経系、心血管系、平滑筋に影響を与えます。高用量では、発作、心律不整脈、そして死を引き起こす可能性があります（ASPCA、2023）。
よくある質問
How much chocolate is toxic to dogs?
Toxicity depends on the type of chocolate and your dog's weight. Milk chocolate becomes toxic at approximately 0.5 oz per pound of body weight. Dark chocolate is 2-3x more toxic. Baking chocolate is the most dangerous — as little as 0.1 oz per pound can be lethal. Use our toxicity calculator to assess your dog's specific risk.
How long after eating chocolate will a dog show symptoms?
Symptoms typically appear within 2-4 hours but can be delayed up to 12 hours. Early signs include vomiting, diarrhea, and restlessness. Severe symptoms (seizures, irregular heartbeat) may appear 6-12 hours after ingestion. Theobromine is absorbed slowly, so symptoms can worsen over time.
Can a dog die from eating chocolate?
Yes, chocolate can be fatal to dogs. The lethal dose of theobromine is approximately 100-500 mg per kg of body weight. For a 20kg (44lb) dog, this equals roughly 200g of milk chocolate or 100g of dark chocolate. Immediate veterinary treatment significantly improves survival rates.
