Does poop green because of biliverdin

Research has found that the reason why dogs poop green is simply that the bilirubin that should be present in the poop has turned into biliverdin. . Strictly speaking, bilirubin and biliverdin are just pigments. Under normal circumstances, there will be a large amount of bilirubin in dog poop.
However, the main reason why dogs have green poop is that biliverdin is reduced to bilirubin through the colon. If there is a problem in the colon, it cannot be restored normally; or there may be too much oxygen in the dog's stomach. The result is that it has been reduced to bilirubin but is oxidized into biliverdin again; or the acidity in the dog's body is too high, causing the biliverdin to lack the necessary conditions to be reduced to bilirubin, so there will be more biliverdin.

Dogs poop green because they are sick

In normal life, if you see a dog pooping green, it means there may be a problem with its colon. For example, colitis, coronaviruses, and parasites can prevent biliverdin from returning to normal. Of course, in addition to these reasons, when a dog eats too much seaweed and other foods, it may also cause the dog to have green stools.

Observe the situation when a dog poops green

So in summary, if the dog usually eats a normal diet and does not eat some weird-colored food, but it poops green, then it is most likely the case. The dog has a gastrointestinal problem. However, if the dog has a special diet and the dog has no other symptoms, then the green poop is most likely caused by eating some special food.
