Hi there. It looks like Bandit had either some mucous or worms stuck to his feces when he pooped. I can't quite tell from your photo, but in either case I would recommend taking the sample to your veterinarian because Bandit will need either a dewormer or some GI medications. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach.
