Is Yeast Dough Safe For My Dog?

To understand how safe yeast dough is for dogs, it’s important to know what happens and the substances that are produced when we use it for bread.

When you knead yeast bread, you activate the gluten in the flour. This creates a stretchy dough that becomes springy once baked.

Once it’s in the oven, yeast dough rises when yeast ferments the sugar present in the ingredients. The fermentation process produces alcohol, carbon dioxide, and heat, which help the bread to rise.

You probably get the drift.

Yeast dough is not safe for your dog because it can cause gas, bloating, and alcohol poisoning.

Why Is Yeast Dough Harmful For Dogs?

Why can’t dogs eat yeast? The dangers are two-fold:

Yeast dough can rise in the stomach of your dog, causing gas and bloating. While these aren’t particularly life-threatening conditions for people, they can result in pain, discomfort, and even stomach ruptures for our pets.

The second danger is the by-product of fermentation. Ethanol is a type of alcohol that can be absorbed into the bloodstream after being digested or passed through unprocessed. This toxin can affect the liver or nervous system and can lead to alcohol poisoning.

What To Do if My Dog Eats Yeast?

Let’s say the worst has happened and your dog has somehow gotten hold of yeast dough and taken a healthy bite out of it. Yeast dough isn’t always lethal but it’s a good idea, given the possibilities, to take your pet to the vet immediately. 

You’ll know your dog is having an adverse reaction to the yeast when it starts:

  • Having a distended and swollen stomach
  • Vomiting but nothing comes up
  • Showing weakness and even falling down

Any amount of yeast dough — no matter how little you think your pet has consumed — can be lethal. Get timely medical attention regardless of the amount ingested.

If your dog develops a distended and swollen stomach, starts dry heaving, or shows weakness, it’s an adverse reaction to yeast dough. Immediate medical attention is necessary.

First Aid Treatment

As a form of first aid, you can try to get your pet to drink some cold water to slow down the fermentation process.

Once you’re at the vet and your dog has been unable to get rid of the dough with vomiting, your vet may force liquid into your dog’s stomach with a tube. This process is referred to as “lavage.” The process is designed to rinse the harmful substance from your dog’s gastrointestinal cavity.

If the lavage is unsuccessful, the removal of the yeast dough by surgery may be required.

Advanced Treatment

In rare cases where the yeast dough might have already done some damage to your dog’s digestive system, your veterinarian may administer IV fluids to help manage symptoms.

IV fluid combined with medication can stabilize your dog’s condition by adding lost electrolytes, lowering blood pressure, and restoring normal heart function.

Frequently Asked Questions

Can Dogs Eat Cooked Yeast Bread?

Even when cooked, yeast dough isn’t safe for dogs. Unfortunately, the warm environment and liquids in your dog’s stomach enable the same chemical reaction that causes yeast to release alcohol.

However, unlike humans, dogs aren’t equipped with the necessary enzymes that break down and process alcohol. As a result, the alcohol can build up in their system and make them very sick, causing vomiting and diarrhea.

Will Raw Yeast Dough Hurt a Dog?

Yes, raw dough can still lead to a sick dog. It is best to keep yeast dough away from your pet.

Similar to cooked yeast dough, raw bread can ferment in dogs’ stomachs and cause alcohol poisoning. Note that even “dried” yeast or baking powder dough that doesn’t rise can pose problems for pets.

Are Yeast Dough and Brewer’s Yeast the Same?

The yeast used for baking is completely different from brewer’s yeast. Visually, it is hard to tell them apart. Your best bet would be to look at the ingredients listed on the package.

Brewer’s yeast is typically used in wine and beer production.
