What causes a dog to pass green stool?
An_221077 posted:
Since moving to NC from MI we've noticed that our dog is passing green stool. No change in food, and no vegatation avaiable for him to eat.
Ernie Ward, DVM responded:
Well, as I practice in NC let me assure you - it's NOT North Carolina! (that would be a light blue color...)

Stool color is largely based on indigestible food components. The second factor in stool coloration is normal excreted digestive products. Dogs with many disease, including liver disease, may develop abnormal color or consistency to their stool. My best guess is food - especially food colorings (think those colorful kibbles you may be feeding).

My advice: take a sample in to have the stool checked for anything unusual or signs of illness. It'll be a great way to meet your new NC vet!
