Dog Diarrhoea and Loose Motion: When to See a Vet

Updated 2026-10-05. General information, not a diagnosis.

Loose motion is one of the most common reasons dogs see a vet. A single soft stool after a change in food is usually nothing. Diarrhoea that keeps going, has blood in it, or comes with vomiting or weakness needs a vet.

Common causes of diarrhoea (loose motion) in dogs

A change of food, or eating something unusual
Worms and other parasites such as Giardia
Bacterial and viral infections, including parvovirus in puppies
Stress, travel or boarding
Food intolerance or allergy
Poisoning, and illnesses of the gut, liver or pancreas

Only a vet who examines your dog can tell which one it is.

What you can do right now

Keep fresh water available. Dogs lose a lot of water with loose motion
Note how often it happens and what the stool looks like. A photo helps
Keep other pets from sharing the same bowl until a vet has checked
Do not give any human medicine. Paracetamol (Crocin, Dolo), ibuprofen and many others are poisonous to dogs and cats, even in small amounts.
