Why is My Dogs Poop Green?

icon June 14, 2023

As a responsible dog owner, it's important to keep a close eye on your furry friend's overall health, including their bathroom habits. One thing that might catch your attention is the color of your dog's poop. While variations in stool color can be normal, seeing green poop in your dog might raise concerns. 
The most common cause of green poop in dogs is that the poop moves through the digestive tract too quickly, which does not allow your dog's body enough time to adequately digest the bilirubin to form a normal brown color.

What is Bilirubin?

In dogs, bilirubin is formed as a byproduct of the normal process of recycling old or damaged red blood cells in the body. It is processed in the liver and then excreted from the body through the bile, which is a fluid produced by the liver that helps in the digestion and absorption of fats.

The color of normal dog feces is usually brown due to the presence of bile pigments, including bilirubin, that are excreted in the stool. However, when the concentration of bilirubin in the bile is high, it can sometimes cause the feces to appear green.

There are a few reasons why bilirubin levels might be elevated in dogs, leading to green poop:

Liver or gallbladder issues: If there is a problem with the liver or gallbladder, such as inflammation, infection, or blockage, it can disrupt the normal flow of bile and result in the accumulation of bilirubin. This can lead to greenish-colored stools.

Diet and rapid digestion: Some dietary factors, such as consuming large amounts of green-colored foods or rapid digestion, can cause bile to pass through the digestive system quickly. When bile moves too rapidly, it may not have enough time to be fully broken down and processed, leading to greenish-colored stools.

Intestinal issues: Certain gastrointestinal conditions, such as malabsorption or maldigestion, can affect the normal absorption and processing of bile pigments. This can result in bilirubin not being fully metabolized, leading to greenish stools.

Green Poop In Dogs

Colitis: The dog's poop will be green because the bilirubin cannot be absorbed properly due to colitis. At the same time, dogs with colitis can also cause frequent diarrhea, abdominal pain, and even blood in the stool, mostly caused by intestinal parasites such as trichomonas, as well as bacteria, viruses, and so on.

What Are the Other Causes of Green Poop in Dogs?


The color of the dog's stool is affected by food, if the dog has recently eaten too much grass or green vegetables, in the food is not completely digested with the feces out of the body, and it will make the dog's stool looks green. If the dog has not recently eaten green food, then green poop is normal.

Ingestion of foreign objects

If your dog ingests something unusual, it could cause changes in the color of its poop. For example, if your dog swallowed a non-food item or a plant with green pigments, it might be reflected in the color of their stool.

What to Do If Your Dog’s Poop Is Green?

 Evaluate any recent changes in your dog's food or treats. Introducing new ingredients, especially those with artificial colorings or additives, can sometimes cause changes in stool color. Consider reverting to the previous diet to see if the green color persists.

If your dog has been grazing on grass or consuming plants, it could explain the change in stool color. Monitor your dog's behavior to prevent excessive ingestion of grass or plants.

If your dog is suffering from digestive problems, proper feeding of canine probiotics can help rebalance the substances in the intestinal tract.

The Number of Poop Per Day for Dogs

A normal healthy puppy has about 3 bowel movements per day, and an adult dog has 1-2 bowel movements per day, depending on the age and type of dog. Defecation time is based on the time the dog eats, generally half an hour after eating dog poop, next we analyze the shape of the dog poop and the color to see if your dog is healthy!

The Color of the Dog's Poop

Brown Poop

Generally healthy dogs, the color of the stool is generally brown. This is the color of your dog's normal digestion and excretion, which is also a healthy color, while if the color is yellow or yellow, the dog may be eating food containing high carbohydrates, such as beans, corn, rice, buns, fruits, vegetables, etc. too high! Normal poop will not have any mucus or blood in it!

White or Gray Poop

If the color of the stool is white or gray, the most common reason is too much bone. Poo of this color is usually divided into small pieces and is dry and crushed when pinched. Be careful to drink plenty of water and reduce the amount of bones fed, otherwise it will cause constipation. If you are not feeding bones, it is likely that stones or roundworms are causing a blockage in the bile ducts, causing the bilirubin to not pass out smoothly with the poop.

Orange Poop

If the stool is orange or orange-yellow in color and thick and unshaped with orange scum, this condition is usually found in dogs with diarrhea and poor digestion.

Red Mucus or Blood Poop

If the dog has red mucus or blood in the stool, this is a very abnormal sign. You can first check to see if it is caused by anal fissures, if not, it may be caused by bleeding in the lower gastrointestinal tract.

(For example, in under 3 months of age puppies, the gastrointestinal function is relatively fragile, due to feeding dry and hard dog food and swallowing foreign objects caused by the case of intestinal scratches

If the dog has depression and bloody stool with fever, it is likely to be caused by acute gastroenteritis. 

If the dog has regular or uninterrupted blood in the stool or blood in the stool, it may be a parasitic problem. The usual symptoms are jelly-like stools with blood or white worms in the stool.)
