Yorkshire Terrier Health Risks — What Every Owner Should Know
Yorkshire Terrier health risks deserve attention early because this compact toy breed marries a bold, terrier-like spirit with documented predispositions affecting the heart, airway, and growing hips—topics that mature quietly before they feel dramatic at home. Large-scale UK primary-care research links higher odds of degenerative mitral valve disease than for crossbreds, while multi-decade hospital case series continue to overrepresent Yorkshire Terriers among small dogs with significant tracheal collapse—patterns clinicians recognise as recurring breed signals in busy small-animal practice. Registry listings and small-breed orthopaedic research likewise support focused vigilance for Legg-Calvé-Perthes disease during the first year of life, when hind-limb lameness is easy to mistake for a simple soft-tissue strain or playful roughhousing that should resolve within days. Yorkshire Terrier health problems, Yorkshire Terrier common diseases highlighted in those sources, and planning across Yorkshire Terrier lifespan inform the overview below. This page distils those sources into plain language for routine wellness planning on BreedRisk—useful for both first-time and long-time owners—acknowledging individual variation between dogs, and all medical content is reviewed by Paulo Morouço, DVM.
Most Common Health Conditions in Yorkshire Terriers
Mitral Valve Disease (MVD)
Degenerative mitral valve disease describes progressive change to the valve between the heart’s left chambers, often recognised first as a murmur before exercise tolerance or breathing patterns shift at home. Breed-aware primary-care research reports substantially elevated odds for Yorkshire Terriers relative to crossbred dogs, with diagnosis timing clustered around the mature adult years in studied populations.
Tracheal Collapse
Tracheal collapse is instability of the windpipe that produces honking cough, noisy breathing, or gagging, often worse with excitement, heat, or collar pressure. Case series spanning decades continue to highlight Yorkshire Terriers among the most frequently affected small breeds, supporting proactive airway history-taking in dogs with compatible cough patterns.
Legg-Calvé-Perthes Disease
Legg-Calvé-Perthes disease is a developmental hip disorder in young dogs where the femoral head bone weakens, producing lameness, pain, or uneven muscle development in a hind limb. Registry and research cohorts list the Yorkshire Terrier as predisposed, so unexplained hind-leg lameness in puppies deserves timely imaging rather than prolonged watchful waiting.
Health Risks by Age for Yorkshire Terriers
Based on cited primary-care, hospital, and orthopaedic references.
| Age Range | Conditions to Watch | Why This Age Matters | Vet Action Recommended |
|---|---|---|---|
| 0–1 years | Legg-Calvé-Perthes disease | Lameness in growing toy breeds may reflect hip osteochondral disruption during rapid development | Hip radiographs when hind-limb gait changes persist; discuss orthopaedic follow-up |
| 3–10 years | Tracheal collapse | Case reports describe median onset around midlife in affected small-breed dogs | Airway-focused evaluation for recurrent honking cough; harness-first handling discussion |
| 7–14 years | Mitral valve disease progression | Primary-care studies show mature-adult clustering for degenerative mitral valve diagnoses | Cardiac auscultation schedule and staging imaging when murmurs or breathing signs appear |
Symptoms to Watch For
Contact your veterinarian promptly if you notice any of the following signs in your Yorkshire Terrier.
- Exercise intolerance, cough at rest, or rapid breathing that may indicate mitral valve disease.
- Honking cough, neck-sensitive breathing noise, or gagging that may indicate tracheal collapse.
- One-sided hind-limb limp, muscle loss, or hip pain in a puppy that may indicate Legg-Calvé-Perthes disease.

Frequently Asked Questions
Are Yorkshire Terriers prone to mitral valve disease?
UK primary-care research reports higher odds of degenerative mitral valve disease in Yorkshire Terriers than in crossbred dogs, with many diagnoses clustered in mature adulthood, so routine cardiac listening remains important from middle age onward. Discuss your dog's individual risk with your veterinarian.
Why is tracheal collapse a concern in Yorkshire Terriers?
Historic and more recent case series continue to list Yorkshire Terriers prominently among small-breed tracheal collapse presentations, which often first show up as honking cough or breathing noise under excitement or collar pressure. Discuss your dog's individual risk with your veterinarian.
Can young Yorkshire Terriers develop Legg-Calvé-Perthes disease?
OFA and research cohorts identify the breed as predisposed, with clinical concern concentrated in the first year of life when lameness or hip discomfort appears in a growing puppy. Discuss your dog's individual risk with your veterinarian.
