Diarrhea in Dogs

Some soft stool or diarrhea in dogs is common with dietary changes or the stress of adapting to a new environment. If your dog has had a small amount of diarrhea once or twice, and if no other symptoms are present (e.g., vomiting, lethargy, not eating) it is acceptable to be patient and continue to monitor him/her. Continued, frequent or large amounts of diarrhea can be a sign of something more serious and could lead to dehydration and weight loss.

Signs that Your Dog Needs to See a Veterinarian

  • Diarrhea continues for more than a day or two
  • Diarrhea becomes more frequent
  • Large amounts of diarrhea
  • Diarrhea is watery or has blood in it
  • Diarrhea is accompanied by other signs of illness (e.g., vomiting, lethargy, not eating)

What You Can Do

  • Closely monitor your dog for the frequency and amount of diarrhea, and whether or not it is bloody or watery.
  • Observe your dog for other signs of illness.
  • Save a fresh stool sample to take to your veterinarian.
  • Give your dog a probiotic such as Fortiflora®, Proviable®, or Benebac®.
  • Add a small amount of canned pumpkin to your dog's food twice a day. Be sure to use real canned pumpkin and not spiced pumpkin pie mix.
  • Encourage your dog to drink more water by using water fountains and placing more bowls of fresh water around the house.
  • Feed canned food, which has more water in it, or add chicken broth to your dog's food.
  • If your dog is new to your home, minimize stress by providing a "safe zone" where your dog can retreat without being bothered by people or other pets.

Common Causes of Diarrhea

  • Intestinal parasites
  • Diet changes or dietary indiscretion
  • Stress
  • Infectious diseases like parvovirus

Treatment of Diarrhea

  • If your dog is dehydrated, intravenous or subcutaneous fluid therapy will be given.
  • If your dog has intestinal parasites, it can be treated with a de-wormer or an anti-protozoal medication.
  • Medication to stop diarrhea may be prescribed.
  • Prescription diets that are highly digestible or are higher in fiber may be helpful.
