Alcohol and Yeast Dough Toxicity

Written By Critter Care Collective .

Alcoholic drinks and rising yeast dough both contain ethanol, which can cause serious toxicity in pets. According to ASPCA poison control, pets often find both surprisingly palatable, making accidental ingestion more common than many pet families realize.

While the source of ethanol may differ, the effects on the body are similar and can become life threatening without prompt treatment.

Why Is It Dangerous?

Ethanol acts as a central nervous system depressant. Once absorbed, it interferes with normal brain function, blood sugar regulation, and body temperature control.

With alcoholic beverages, ethanol is absorbed quickly, and signs may begin within 30 minutes. With yeast dough, ethanol is produced as the dough continues to ferment inside the stomach, leading to delayed and unpredictable onset of signs, sometimes hours after ingestion.

Yeast dough also produces carbon dioxide, which can cause dangerous stomach distension, increasing the risk of bloat or gastric dilatation volvulus in dogs.

Who’s Most at Risk?

  • Dogs that have access to unattended alcoholic drinks at parties or gatherings

  • Dogs that counter surf or steal raw dough

  • Small dogs, where even small amounts can cause severe toxicity

  • Pets with underlying neurologic disease

  • Puppies and kittens

Signs of Alcohol or Yeast Dough Toxicity

Symptoms may include:

  • Ataxia or loss of coordination

  • Lethargy or depression

  • Disorientation or vocalization

  • Vomiting

  • Hypothermia

  • Rapid heart rate or breathing difficulty

  • Tremors or seizures

  • Recumbency or coma

  • Aspiration pneumonia

Signs can worsen quickly and should always be treated as an emergency.

What To Do If Your Pet Is Exposed

  • Do not wait for symptoms to appear.

  • Never induce vomiting at home unless specifically directed by a veterinarian or poison control, especially if your pet is already showing signs of intoxication.

  • Contact poison control immediately.

    • ASPCA poison control: 888-426-4435

    • Be prepared to share what was ingested, when it happened, and your pet’s size and current symptoms.

What to Expect at the Vet

There is no antidote for ethanol toxicity, so treatment focuses on supportive care. Depending on severity, your pet may receive:

  • Intravenous fluids for hydration and support

  • Antiemetics to reduce aspiration risk

  • Blood glucose monitoring with dextrose supplementation if needed

  • Temperature support

  • Medications to control tremors or seizures

  • Oxygen therapy or airway protection in severe cases

Pets that ingest yeast dough may also be evaluated for gastric distension or bloat.

Recovery can range from several hours to multiple days depending on the amount ingested and how quickly treatment begins.

Prevention Tips

  • Keep alcoholic drinks out of reach at all times

  • Dispose of unfinished drinks promptly

  • Store bread and pizza dough securely

  • Supervise pets closely during holidays and gatherings

  • Ask guests not to share food or drinks with pets

Final Thoughts

Alcohol and yeast dough exposures can lead to rapid neurologic depression, metabolic disturbances, and serious complications in pets. Early recognition and prompt veterinary care greatly improve outcomes.

If you suspect your pet has been exposed, contact your veterinarian or ASPCA poison control immediately at 888-426-4435.
