As the saying goes, “Your digestive system has no secrets, it reveals what you’ve consumed.” Similarly, your dog poop reveals everything about their stomach. So we must ask “Why is my dog’s poop green?“🤢

Why Is My Dog’s Poop Green

Sometimes it’s normal for dogs to poop green but many times it can be a signal of tummy troubles, let’s dig in and find out everything about green poop so that we can help our dogs to live a healthy life.

Why Is My Dog’s Poop Green?

Colour, size, form, and smell are indicators of how well your dog is digesting the food. If we find any unusual sign it is always wise to consult with the vet. Let’s see the reasons in detail:

1. Diet

Green poop in dogs is often related to what they consumed. This can occur if they eat large amounts of green vegetables, especially if they are rich in chlorophyll.🟢 Some dog foods may also contain artificial dyes that can affect the colour of their poop. This is usually harmless!

Moreover, if your dog eats grass, this can lead to greenish poop as well. Generally, diet-related green poop is not a reason to worry and should return to normal colour when their diet changes in some days.

2. Parasite Infection

"The parasites irritate the intestines, leading to certain intestinal parasites, such as giardia, which can eventually cause changes in poop colour, including greenish pigments", says Tammy Hunter at VCA.🏥

If your dog is experiencing a parasitic infection, they may display other symptoms like diarrhoea, vomiting, lethargy, and weight loss. It’s essential to consult your vet if you suspect a parasitic infection for proper diagnosis and treatment.

3. Poisoning

Ingesting toxins like rat poison can also cause poop to be green. It can also lead to other symptoms like vomiting, diarrhoea, seizures, drooling, and general distress.

If you suspect that your dog has consumed something toxic immediately take your dog to the emergency animal care, where a vet can examine them and provide the right diagnosis.📝

4. Stomach Issues

Stomach problems or issues in the gastrointestinal tract can disrupt the normal digestive process, leading to changes in poop colour, form, and frequency.

Conditions like malabsorption, inflammatory bowel disease (IBD), or an upset stomach can result in greenish poop. Problems with the liver and gallbladder can contribute to the issue.

Additionally, Excessive bacteria in the intestines from conditions like small intestinal bacterial overgrowth (SIBO) can also cause green poop. If your dog has constant stomach issues, it’s crucial to seek a vet’s🧑‍⚕️ help to figure out the cause and solution.

5. Food Intolerance

If your dog eats anything that is not suitable for their digestive process their poop colour may change. If he is suddenly pooping green then it may be because of food intolerance.

When you try to introduce a new food or any food item changing your dog’s regular diet they may require some time to adjust to your dog’s digestive system.

They may also gobble down something when they are out on the walk,🛣️ leading to stomach issues. If your dog continues to poop green for a longer duration try changing his diet back to the previous one.

What to Do if Your Dog Is Pooping Green?

If your dog is pooping green but otherwise acting normal then monitor their diet for a few days. Feed dogs a nutritious diet🥣 so that they don't crave or eat something from outside.
