今すぐペットのリスクを評価
| 殺鼠剤タイプ | 有効成分 | リスクレベル | 必要な対処 |
|---|---|---|---|
| Anticoagulant (multi-dose) | Brodifacoum, Bromadiolone | CRITICAL | 🚨 Emergency vet NOW — internal bleeding delayed |
| Neurotoxic | Bromethalin, Strychnine | CRITICAL | 🚨 Emergency vet NOW — seizures within hours |
| Cholecalciferol | Vitamin D3 | HIGH | 🚨 Emergency vet NOW — kidney failure |
今すぐやるべきこと

Step 1: This Is a Dire Emergency
Do NOT wait for symptoms. Anticoagulant rodenticides have a 2-5 day delay before bleeding begins. By the time symptoms appear, the damage is done. Call ASPCA Poison Control at (888) 426-4435 NOW.

Step 2: Bring the Product Package
Take the bait package or a photo to the vet. The active ingredient determines treatment: anticoagulants need Vitamin K1; bromethalin needs brain swelling management; cholecalciferol needs calcium-lowering therapy.

Step 3: Go to Emergency Vet for Decontamination
Your vet will induce vomiting (if within 1-2 hours), administer activated charcoal, and start specific antidotes. For anticoagulants: Vitamin K1 for 4-6 weeks with blood clotting tests.

Step 4: Hospitalization May Be Required
Bromethalin poisoning requires 24-72 hour monitoring with mannitol for brain swelling. Anticoagulant cases need plasma transfusions if bleeding is active. Early treatment dramatically improves survival.
その背後の科学
抗凝固殺鼠剤はビタミンKエポキシドレダクターゼ（VKOR）を阻害し、ビタミンKのリサイクルを防ぎます。これにより活性凝固因子（II、VII、IX、X）が枯渇し、自然出血を引き起こします。第2世代抗凝固剤（ジフェナクム、ブロマジオロンナ）はワルファリンの100倍の効力を持ち、肝臓に数週間残留します。ブロメタリンは脳細胞の酸化的リン酸化を脱共役し、脳浮腫と頭蓋内圧亢進を引き起こします。コレカルシフェロール（ビタミンD3）は高カルシウム血症を引き起こし、腎臓、心臓、血管の転移性石灰化を引き起こします（ASPCA、2023）。
よくある質問
Is rat poison deadly to dogs?
Yes, rat poison (rodenticide) is one of the most deadly toxins for dogs. There are two main types: (1) Anticoagulant rodenticides (warfarin, bromadiolone, brodifacoum) — prevent blood clotting, causing fatal internal bleeding. Single-dose types require one feeding; multiple-dose types are cumulative. (2) Neurotoxic rodenticides (bromethalin, strychnine, cholecalciferol) — cause brain swelling, seizures, or hypercalcium within hours. Without treatment, mortality rates are 50-90%.
What are the symptoms of rat poison in dogs?
Anticoagulant symptoms appear 2-5 days after ingestion: weakness, pale gums, coughing blood, bloody vomit/diarrhea, nosebleeds, and collapse. Neurotoxic (bromethalin) symptoms appear within 2-24 hours: severe muscle tremors, seizures, ataxia, and paralysis. Cholecalciferol causes kidney failure with increased thirst/urination within 12-36 hours.
Can my dog survive rat poison?
Yes, with immediate treatment. Anticoagulant poisoning is treatable with Vitamin K1 for 4-6 weeks; survival rate is 80-90% if treated before symptoms appear. Bromethalin has no antidote — treatment is supportive care (activated charcoal, mannitol for brain swelling) with 50-70% survival if treated early. Strychnine and cholecalciferol also require immediate veterinary intervention.
What should I do if my dog ate rat poison?
Treat this as a dire emergency: (1) Call ASPCA Poison Control at (888) 426-4435 immediately. (2) Go to the nearest emergency vet NOW — do not wait for symptoms. (3) Bring the product label to identify the active ingredient. (4) Induced vomiting within 1-2 hours may help prevent absorption. (5) Even if your dog seems fine, delayed symptoms are common and early treatment is life-saving.
