Eggs Smell Like Wet Dog: What To Do? 

Throughout history, eggs have been a staple member of the cousine. But why does such an important food have such an abhorrent smell?

We all know eggs have that distinctive pungent smell. 

So why do eggs smell like wet dog? 

The blame for eggs smelling like wet dogs can be put on hydrogen sulfide. It is a gas that creates the pungent smell of wet dogs in eggs. Heat, time, and pH are factors in creating hydrogen sulfide in eggs. Using vinegar while boiling the egg can help mitigate the smell.

The Smell of Wet Dogs

We have all had an experience like this. A lovely walk by the lake with your dog. Your dog goes swimming with the ducks, you take cute pictures of your dog. 

But then the journey back home becomes a real challenge. Let’s hope you took a mask with you because the smell is not pleasant. For some reason, your cutest dog smells worse than a skunk.

It was just a bath in clear lake water. But why the repugnant smell from the dog? 

Reason Behind Dog’s Smell 

Yeast and bacteria are the ones creating your wet dog’s disgusting smell. Yeast and bacteria make a home in your dog’s skin and fur. Like all of us, your dog is carrying a huge amount of the microorganisms around. 

While living their lives, yeast and bacteria leave behind a volatile organic compound. It is basically the micro excreta of the microorganisms. 

Now the organic compound is the main reason behind the pungent smell. The wet dog smell comes from the moisture evaporating from the wet dog. The evaporation carries some of the compound. 

Dogs that have large skin flaps smell way worse. This is because the flaps retain moisture for longer. So all dogs with wrinkly skin or skinkly face have a worse wet dog smell. 

Why Do Eggs Smell Like Wet Dogs?

Wondering why do eggs smell bad to me? Well, this is not just you. It smells bad for everyone.  

Do you know what smelly water in wells, geysers, and eggs have in common? The same distinctive and unpleasant smell. They all have that smell of sulfur. 

Egg whites are 88% water and 11% proteins. The most common protein is ovalbumin. And what does ovalbumin have? Bunch of sulfur atoms. 

Sulfur itself is an odorless element in crystalline form. It only gives off the smell in a gaseous state. 

So to answer why egg smell bad?

Egg smells bad. That’s because when an egg is boiled, the ovalbumin protein breaks apart. This causes chemical reactions and creates hydrogen sulfide gas. This is what gives off the bad smell of eggs. This is also like the smell of wet dogs. 

The process mentioned above occurs in aging eggs too. But the heat from the boiling speeds up the process significantly.  Boiling water creates hydrogen sulfide 200 times faster than the normal aging process. 

Now as the egg boils, more and more hydrogen sulfide is released into the air. The gas moves inwards towards the yolk. As well as moving outwards towards the air. 

The hydrogen sulfide reacts with the iron present in the yolk. This creates new chemicals named ferrous sulfide and ferric sulfide. 

The new chemicals can be seen as the dark, green-yellowish ring around the yolk. The more the egg has been heated, the darker the rings and more smell. 

Three Factors Behind the Smell

The general discussion we just went through gives us an idea of the two factors; time and heat. But the other factor that makes eggs smell like fish went unmentioned. The third factor being pH.

Now let’s look into the three factors more specifically. 


With time the hydrogen sulfide atoms grow in number. Leaving an egg will over time create hydrogen sulfide atoms inside and spoil the egg. 

Time plays a huge role in cooking as well. Eggs can overcook really quickly. So have a plate ready to go before you start cooking. 

While cooking an egg, an extra 30 seconds in the heat can matter a lot. That small amount of time for the hydrogen sulfide atoms is enough to proliferate. Creating a disgusting smell. 


Another key factor behind the smell is heat. The heat is what helps break the protein and create the hydrogen sulfide atoms. 

The nasty smell starts to develop after the temperature goes above 180 degrees F.  

Cooking is done at a similar or higher temperature, so cooking increases the smell. 

Maintaining the proper temperature will help control the creation of hydrogen sulfide. But be careful, maintaining heat can be tricky. Improper maintenance can make even cooking cinnamon rolls difficult. 


Now the final factor behind the smell is pH. The number of hydrogen sulfide increases as the pH of the egg increases. This results in them smelling like wet dogs.

How to Make Boiled Eggs That Don’t Smell?

We have been going on and on about what makes eggs smell like wet dogs. But is there no way to mitigate the smell? Well, there certainly is, let’s look into them. 

Step 1: Using Vinegar

Begin by placing the eggs in a saucepan of cool water. Make sure the saucepan has one or two inches of water covering the egg. 

Now add a few teaspoons of vinegar in the water. The vinegar will neutralize the bad smell of the eggs.  It will do so without affecting the taste of the egg. 

Here’s our recommendation for best quality vinegars out there.

Step 2: Boiling the Egg

Now start boiling the egg in the saucepan. Remove the saucepan from the stove. Immediately cover it with a lid as soon as the water boils.

Let the saucepan sit off the burner for around 15-20 minutes. 

Step 3: Pouring Cold Water

Now pour cold water over the eggs. Or just place the eggs in cold water. Do this right after the egg finishes sitting in the boiled water. Bathe the eggs in cold water just like water bathing pickles

The cold water stops the cooking process of the eggs. This in turn prevents the yolk from turning greenish-yellow and creating hydrogen sulfide. 

Step 4: Ventilating the Kitchen

Now open the windows of the kitchen and increase the airflow as much as possible. The air circulation will help reduce the smell of the egg. 

Placing shallow bowls of vinegar around the room will also help. The vinegar helps neutralize the lingering smell of the egg. 

For ventilation, you can use our recommended ventilation fans.

Step 5: Clearing the Kitchen

Now if there is any lingering smell left in the kitchen, it can be dealt with. Boil a pot of diluted vinegar. The scent of vinegar will be gone with the water. 

That’s it! Hope we were able to bring to you everything you wanted. 

Frequently Asked Questions (FAQs)

Why Do Scrambled Eggs Smell Bad?

When an egg is cooked, the ovalbumin protein present in egg white breaks apart. This causes chemical reactions and creates hydrogen sulfide gas. The heat helps the process of creating hydrogen sulfide. Hydrogen sulfide gives off a nasty smell. That is why fried, also boiled, eggs have a bad smell.

How to get rid Of the bad smell Of Eggs During Cooking?

There are a few ways to mitigate the smell. Adding a few tablespoons of vinegar while boiling the egg can help lessen the smell significantly. The vinegar neutralizes the smell of the hydrogen sulfide atoms. Pouring cold water over the eggs after boiling helps to prevent the smell as well. 

Why Do Bad Eggs Float?

With time, the air pockets inside the egg grow larger. This is because the protein inside the egg breaks and creates hydrogen sulfide gas inside the egg. The gas moves inwards and affects the yolk as well. The excess presence of gas inside the egg helps it float. 


And with that we know so much more regarding eggs smell like wet dog. The smell is mainly caused by sulfur gas. Both cooked and old eggs have more hydrogen sulfide inside them. That is what makes them smell like wet dogs. 

The smell can be mitigated by following some ways. Using vinegar while boiling the eggs helps lessen the smell drastically.
