Diarrhea in Yorkies
Diarrhea is loose, watery, or unformed stool. Most diarrhea episodes resolve in 24-48 hours with simple home care, but persistent or severe diarrhea (especially with blood) needs veterinary attention.
About Yorkies
Tiny, bold, lively terriers with long silky coats. Toy-breed size means specific health considerations — especially dental and tracheal.
Health predispositions in Yorkies
- Dental disease (small mouth, crowded teeth)
- Tracheal collapse
- Hypoglycemia (especially in young or stressed Yorkies)
- Luxating patella
- Liver shunts
- Skin allergies
Predispositions don't mean your individual Yorkshire Terrier will develop any of these conditions. They just mean these are seen more often in the breed than in the general dog population.
Common causes of diarrhea
These are common causes across all breeds, including Yorkies:
- Dietary indiscretion
- Sudden diet change
- Stress (boarding, travel, new pet)
- Intestinal parasites (worms, giardia)
- Viral or bacterial gut infections
- Food allergies or intolerance
- Inflammatory bowel disease
- Pancreatitis
- Toxin or medication reaction
- Some cancers
Red flags — call a vet immediately
- ⚠ Diarrhea with blood (red streaks or black/tarry stool)
- ⚠ Diarrhea with severe lethargy or weakness
- ⚠ Persistent diarrhea over 48 hours
- ⚠ Diarrhea in a puppy or senior pet
- ⚠ Diarrhea with vomiting (dehydration risk)
- ⚠ Diarrhea after possible toxin exposure
Any of these in your Yorkshire Terrier means stop reading the internet and call a vet or go to an emergency clinic. RexVet can help triage by video if you're not sure — but emergencies need in-person care.
