My dog's poop is two colors. Should I worry about new supplements?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 9 months and 5 days old | 13 lbs

Yesterday my dog pooped out in two different tones half of it was a lighter brown and other half a dark color i picked it up with a paper towel and it left like a very dark color residue. Today she pooped normal color. Should I be concerned? We did start naturvet all in one supplements and they are a dark color. She is her normal self and eating normal. Should I be concerned?

Shades of stool color can vary widely from day to day, hour to hour, or (as you experienced) within the same bowel movement. Typically, diet and supplements are the main sources of changes in stool color, so the supplement that you're using may be to blame. The color of the supplement or food are less to blame for the color change than the way some of the vitamins and minerals digest. Regardless, since Chispas is still eating and acting normally, there's no cause for concern. Shades of brown in stool are all normal. However, colors like black, red, or white stool are all signs that something is amiss. Based on what you've described, I don't think you need to be concerned in the slightest!
