Short answer

Yes, that's harmful. Regular ethanol exposure builds up in a dog's system and can cause cumulative damage to the liver and nervous system over weeks. Even small daily amounts that don't cause obvious wobbliness can still lead to chronic low blood sugar and organ strain. You might notice subtle changes first, like a dull coat or less energy. Stop this practice immediately and call your own vet to discuss any long-term effects and for a safer way to share bonding time.

Why is Ethanol Dangerous for Pets?

Ethanol, or ethyl alcohol, is rapidly absorbed from a pet's stomach and intestines.

Pets are much more sensitive to its effects than humans, and it can cause a dangerous drop in blood sugar, body temperature, and blood pressure.

Severe poisoning can lead to respiratory failure, coma, or death.

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, and excessive drooling.
  • Loss of coordination, appearing wobbly or 'drunk'.
  • Lethargy, depression, or weakness.
  • Slow or difficult breathing.
  • Low body temperature (hypothermia).
  • Tremors, seizures, or collapse.

What to do right now

  1. Call your veterinarian or a pet poison helpline immediately.
  2. Do NOT induce vomiting unless specifically instructed by a professional.
  3. If the product is on the skin or fur, rinse thoroughly with water.
  4. Keep your pet warm and calm while transporting to the vet.
  5. Bring the product container with you to the veterinary clinic.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
