今すぐペットのリスクを評価
| 飲料タイプ | 摂取量 | リスクレベル | 必要な対処 |
|---|---|---|---|
| Liquor (40%+) | > 1 oz | CRITICAL | 🚨 Emergency vet NOW |
| Wine/Beer (5-15%) | > 4 oz | High | 📞 Call vet immediately |
| Any alcohol | < 0.5 oz | Moderate | 👀 Monitor, call vet for advice |
今すぐやるべきこと
- 1
Step 1: Remove All Alcohol Immediately
Take away any remaining beverages, food containing alcohol, or raw bread dough. Clean up any spills — dogs may lick floors.
- 2
Step 2: Assess Your Dog's Neurological State
Check: Can your dog walk normally? Are they alert or depressed? Vomiting? If your dog cannot stand or is unconscious — go to emergency vet NOW.

Step 3: Call Poison Control
📞 ASPCA Poison Control: (888) 426-4435. Calculate approximate alcohol consumed in grams: volume (mL) × alcohol% × 0.789 = grams of ethanol.

Step 4: Keep Your Dog Safe
Prevent falls due to ataxia. Keep your dog warm — alcohol causes vasodilation and hypothermia. Do NOT leave them unattended. Monitor breathing and consciousness every 15 minutes.
その背後の科学
エタノール（C2H5OH）はGI管から迅速に吸収され、数分以内に血液脳関門を通過します。犬は効率的なアルコール脱水素酵素酵素を欠いているため、人間の3-5倍感受性が高いです。エタノールはNMDA受容体を阻害し、GABA活性を高め、CNS抑制、呼吸抑制、代謝性アシドーシスを引き起こします。犬の致死量は純エタノール5.5mL/kgです。生パン生地は二重に危険です—温かい胃の中で酵母発酵が続き、より多くのアルコールを生成し、生地が膨張します（ASPCA、2023）。
有毒量計算機
摂取量: 純エタノール1.5mL/kgでも目立った中毒を引き起こす可能性があります
LD50: LD50：純エタノール約5.5mL/kg
その背後の科学: 出典：Merck Veterinary Manual；ASPCA動物毒物管理センター
例：1本の12ozビール（5%ABV=17gエタノール）でも、10kg未満の小型犬に重度の中毒を引き起こす可能性があります。
症状のタイムライン：何を期待するか
Early signs: disorientation, ataxia (wobbly gait), vomiting, depression
Severe signs: slowed breathing, metabolic acidosis, hypothermia, hypoglycemia (especially small dogs/puppies)
Resolution with supportive care: IV fluids, glucose, blood pH monitoring; unmonitored cases risk coma or death
よくある質問
Is alcohol toxic to dogs?
Yes, alcohol (ethanol) is highly toxic to dogs. The lethal dose is 5.5 mL/kg of pure ethanol. Dogs are much more sensitive than humans because they lack efficient alcohol dehydrogenase enzymes. Even small amounts cause ataxia, depression, and metabolic acidosis. Beer, wine, liquor, and raw bread dough all pose serious risks.
What are the symptoms of alcohol poisoning in dogs?
Symptoms appear within 30-90 minutes: disorientation, loss of coordination (ataxia), vomiting, depression, slowed breathing, metabolic acidosis, and in severe cases, coma and death. Hypoglycemia (low blood sugar) is a dangerous complication, especially in small dogs and puppies.
Can beer kill a dog?
Yes, beer can kill a dog. A single 12oz beer (5% alcohol = 17g ethanol) can cause severe intoxication in a small dog (under 10kg). Dogs metabolize alcohol much slower than humans, so effects accumulate. Carbonation also speeds absorption. Never intentionally give alcohol to dogs.
What should I do if my dog accidentally drank alcohol?
Call ASPCA Poison Control at (888) 426-4435 or your vet immediately. Do NOT induce vomiting if your dog shows neurological symptoms (depression, ataxia). Remove any remaining alcohol. Keep your dog warm and safe from falls. Your vet may need to administer IV fluids, glucose, and monitor blood pH.
