Why does my dog keep having runny stool every few days?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 6 years and 4 months old | 17 lbs

My dog sees to have a runny stool every three to four days. There has been no change in diet or life style other than getting her nails clipped. Can you give me some ideas why this would be happening?

It sounds like your dog has a case of colitis, or an inflammation of the colon. Colitis can be caused by many different things. Some of the more common causes include intestinal parasites, dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis, a foreign body/blockage and viruses. Since the abnormal stool has been happening repeatedly I would recommend taking a stool sample in to your vet’s office to be examined for intestinal parasites. If he does not have worms then your vet will need to do a work up to determine what is causing the abnormal stools. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
