今すぐやるべきこと
- 1
EMERGENCY VET NOW
Go to the nearest emergency vet immediately. Call ASPCA Poison Control at (888) 426-4435 en route. Every minute counts.
- 2
Do NOT Wait for Symptoms
By the time symptoms appear, kidney damage may be irreversible. The antidote must be given within 8-12 hours to be effective.
- 3
Bring the Container
Take the antifreeze container to the vet. This confirms the active ingredient (ethylene glycol) and concentration.

Treatment Window is Critical
Your vet will administer fomepizole (4-MP) or ethanol IV to block metabolism. After 12 hours, treatment is much less effective.
その背後の科学
エチレングリコール自体は有毒ではありません—肝臓によって生成される代謝物が損傷を引き起こします。アルコール脱水素酵素はエチレングリコールをグリコアルデヒド、次いでグリコール酸、そしてシュウ酸に変換します。シュウ酸はカルシウムと結合してシュウ酸カルシウム結晶を形成し、腎組織を破壊します。このプロセスは代謝性アシドーシスと急性腎不全を12-36時間以内に引き起こします。解毒剤はアルコール脱水素酵素を阻害し、有毒な代謝物の形成を防ぐことで機能します（ASPCA、2023）。
よくある質問
How much antifreeze is lethal to dogs?
As little as 1 teaspoon (5ml) of antifreeze can kill a 10lb (4.5kg) dog. The lethal dose of ethylene glycol is approximately 4.4ml per kg of body weight. This makes antifreeze one of the most dangerous household toxins for pets.
How fast does antifreeze kill dogs?
Without treatment, antifreeze is fatal within 12-36 hours. The antidote (fomepizole or ethanol) must be administered within 8-12 hours of ingestion to be effective. After kidney failure begins, survival rates drop dramatically.
What are the symptoms of antifreeze poisoning?
Stage 1 (30 min-12 hrs): drunken behavior, vomiting, seizures. Stage 2 (12-24 hrs): apparent improvement (misleading). Stage 3 (24-72 hrs): kidney failure, severe lethargy, mouth ulcers, coma. Early treatment is critical.
