Short answer

Yes, call your vet or the ASPCA poison line at 888-426-4435 now. For a dog that small, even a few sips can cause serious intoxication. Watch for wobbling, vomiting, or unusual quietness. Keep him warm and calm while you arrange immediate transport to the clinic for IV fluids and monitoring.

Why Alcohol Is Dangerous for Dogs and Cats

Alcohol contains ethanol which pets metabolize slowly, leading to rapid intoxication.

Even small amounts of beer, wine or spirits can cause vomiting, depression and potentially life‑threatening complications.

Dogs are especially sensitive, while cats may show more severe neurological signs.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Vomiting
  • Diarrhea
  • Lethargy or depression
  • Uncoordinated gait or stumbling
  • Hypothermia
  • Seizures in severe cases

What to do right now

  1. Call your veterinarian or an animal poison control center immediately
  2. Do not induce vomiting unless instructed by a professional
  3. If the pet is conscious keep them warm and quiet
  4. Monitor breathing and heart rate and be prepared to provide CPR if needed
  5. Transport the animal to the clinic for IV fluids and supportive care
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
