Chronic diarrhoea is defined as diarrhoea that is present for longer than 2 weeks, or is episodic, or intermittent.

The diagnostic approach should include:

  • History:
    • Toxin or foreign body ingestion?
    • Worming status.
    • Travel history.
    • Dietary history.
    • Presence of signs in in-contact animals?
    • Presence of systemic signs?
    • Weight loss?

 

  • Physical examination:
    • Vital signs.
    • Hydration status.
    • Body condition score.
    • Check oral mucous membranes (anaemia, jaundice).
    • Check under tongue (for linear foreign body).
    • Palpate abdomen (foreign body, mass, effusion, thickened or bunched intestines, pain, organomegaly).
    • Rectal examination (mass, foreign body, melena).
    • Ascites or peripheral oedema can be seen in protein-losing enteropathy (PLE).
    • Skin signs can be present in cases of dietary sensitivity.
    • Examine the rest of the dog to find signs of systemic disease.
