Yellow
Bright yellow, greasy stool may signal bile dilution issues or food intolerances.

FAQ
What color should healthy dog poop be?
Most vets consider medium-to-dark brown ideal because it shows bile has had time to break down food. Healthy stool is shaped like logs, easy to pick up, and not overly dry or slimy.
Is green dog poop bad?
Green poop can simply mean your dog ate grass or plant-heavy treats, but persistent green stool may point to GI upset or parasites. Monitor closely and call your vet if it lasts longer than a day or includes other symptoms.
What does black dog poop mean?
Black, tarry stool often indicates digested blood from the stomach or small intestine (melena). This can be an emergency. Contact your veterinarian immediately if you see inky or coffee-ground stool.
Why is my dog's poop yellow?
Yellow stool can occur when food moves too quickly through the intestines, with food intolerances, or with infections like giardia. Track appetite and energy; call your vet if yellow stool persists or is greasy and foul-smelling.
When should I call a vet about stool color?
Contact your vet for black/tarry stool, gray or pale stool, large amounts of red blood, white specks that move, or any color change paired with vomiting, lethargy, or refusal to eat.
Can food change dog poop color?
Yes. Colorful treats, carrots, pumpkin, charcoal biscuits, and even new kibble formulas can tint stool temporarily. If the change fades after a day and your dog feels good, it was likely diet-related.
