Yorkshire Terrier Health Conditions#

Portosystemic Shunt

life_threateningModerate
Typical onset:02 years

Abnormal blood vessel bypassing liver. Yorkies have highest prevalence.

Prevention: Bile acid test for early detection.

Symptoms: poor growth, disorientation after eating, seizures

Hypoglycemia

life_threateningCommon
Typical onset:00.5 years

Dangerously low blood sugar, especially in puppies under 4 months. Toy breed puppies have minimal glycogen reserves and high metabolic rates. Signs include lethargy, trembling, and seizures. Frequent small meals prevent episodes.

Prevention: Frequent small meals. Karo syrup for emergencies.

Symptoms: lethargy, trembling, seizures

Dental Disease

moderateVery Common
Typical onset:13 years

Toy breeds accumulate tartar at accelerated rates due to crowded teeth in a small jaw. Yorkies are among the worst affected — periodontal disease can lead to tooth loss, jaw bone deterioration, and bacterial spread to heart valves.

Prevention: Daily brushing. Professional cleanings.

Symptoms: bad breath, red gums, loose teeth

Patellar Luxation

moderateCommon
Typical onset:15 years

Kneecap slides out of its femoral groove, causing intermittent lameness and skipping gait. Graded I-IV; grades III-IV often require surgical correction. Very common in toy breeds due to shallow patellar grooves.

Prevention: Maintain healthy weight. Surgery for severe grades.

Symptoms: intermittent skipping, holding up hind leg

Collapsing Trachea

seriousCommon
Typical onset:38 years

Tracheal cartilage rings weaken and flatten, narrowing the airway. Causes characteristic 'goose honk' cough, especially with excitement or leash pressure. Progressive condition managed with weight control, harnesses, and sometimes surgery.

Prevention: Use harness. Maintain weight.

Symptoms: honking cough, exercise intolerance
