Why Does Dog Poop Turn White? Causes and Solutions

Table of Contents

You might be wondering, why does dog poop turn white? There are a number of factors that can affect the color of dog poop. Digestive systems, diet, and medications can all affect the composition of your dog’s poop.

For example, if your dog has been eating a lot of white bread or cauliflower, their poop might turn white because these foods contain high levels of undigested proteins.

The color generally depends on what your dog ate. For example, if the poop turns more grey-ish, it’s because of indigestible food items like bones, hair, or whole prey animals.

Eating grains or plant matter may make your dog’s poop look yellow or brown. If your dog eats corn or soybeans, for instance, his poop will likely be mostly yellow or brown with some white bits. 

Some dogs also eat grass to help with upset stomachs. When this happens, your dog’s poop might turn light green for a short period of time before it eventually turns back to normal.

Here are things that may cause your dog’s poop to turn white or smell bad.

Why does dog poop turn white?

There are many factors that can affect the color of your pet’s waste. Some common reasons for light or white dog poop are:

  • The diet – White dog poop is often created when pets eat foods with grains, which contain carbohydrates that break down into sugar in their system. 
  • Medications – If your pet has been taking medication, it may result in a change in the color of their stool.
  • Gastrointestinal diseases – Diseases such as cancer and inflammatory bowel disease may also cause a shift in the color of your pet’s waste.

What causes dog’s poop to turn white?

Your dog could have a food intolerance that causes white-colored poop, or it could simply be a matter of genetics.

Dogs of certain breeds, such as Akitas and Siberian Huskies, tend to have white poop.

You might also notice a white tinge to dog’s poop if they eat lots of white, wheat-containing products.

Some breeds are prone to diarrhea. The amount of water your dog has to drink with their food can also affect the color of their poop.

So if you notice your dog is drinking less water with their food, your dog may be constipated.

This may cause excessive gas, which makes it hard for the feces to move through the digestive tract.

How does diet affect the color of dog poop?

How diet affects the color of dog poop depends on which diet your dog is on. These dietary factors affect the color of your dog’s poop depending on whether they’re high in fats or carbohydrates.

When your dog is on a high-fat diet, it can turn his poop yellow. It may also turn green if your dog has ingested sedatives.

If your dog is on a high-carb diet, the color of his poop might change if he’s eating white carbohydrates.

If you’re using human food coloring to color your dog’s food, his poop may change before it finally changes to the normal color.

If your dog is on a low-fat diet, his poop might start looking blue for a short period of time before it starts to brown.

High-fat dogs might also poop orange and cream-colored in the beginning.

What you should do if your dog’s poop turns white?

You might be able to flush out the color of your dog’s poop by getting your dog to eat a bland diet. This means your dog can’t eat anything else. (You can also try giving your dog fresh water instead of frozen or distilled water to help avoid digestive issues.)

You might also have to change what you feed your dog, but keep in mind that grains are included in many human foods.

Therefore, if your dog has a sensitive stomach, a bland diet might not be a good idea.

If you still want to try giving your dog a bland diet, try egg whites instead of whole eggs. Egg whites are a good source of protein that your dog can digest without a problem.


There’s a reason why dog’s poop might turn white. While some causes can be easily fixed (like brushing the dog more often), others are not so easily solved.

However, the good news is that most of these problems should resolve themselves as your dog gets older and more settled in his new home.

You just have to be patient and try to observe what your dog does to figure out what might be causing the problem.

Hopefully, by learning about the causes of dog poop, you’ll be able to figure out what’s going on with your pup without a trip to the vet.
