About

What is a Shih Tzu?

Small, sturdy toy breed with a distinctive short snout, large dark eyes, and luxurious long flowing double coat. Known for their charming, affectionate companion temperament

Shih Tzu history and origins

Ancient breed developed in Tibetan monasteries and refined by imperial breeders in Chinese palace courts. Believed to descend from Tibetan breeds, possibly crosses between Lhasa Apso and Pekingese, prized as house pets for centuries

Shih Tzu appearance and size

Typically 4-7 kg and 23-27 cm at the shoulder — published as one range rather than separately for males and females.

Extraído de fuentes y no escrito como opinión — investigación de salud citada, el estándar del propio registro, y estudios de longevidad revisados por pares. Estándar de la raza, FCI; The Royal Kennel Club - RFG scheme expansion for Crufts 2026. Los animales de un criador pueden diferir de todo esto, y una columna vacía significa que no tenemos nada de ese lado, no que no haya nada que decir.

Bones & joints

Patellar luxation

Monitor

The kneecap slips out of its groove; the American Shih Tzu Club recommends screening for a CHIC number.

Qué pedir

OFA patellar luxation exam (graded 0-4) on both parents.

1 source

Chondrodystrophy with intervertebral disc disease risk (CDDY/IVDD)

Serious

An FGF4 retrogene variant alters disc structure and raises the risk of disc degeneration and herniation. Shih Tzu is one of the breeds OFA names for this DNA test, and insurance-database studies put lifetime IVDD prevalence in the breed at roughly 3.5-5%, well above non-chondrodystrophic breeds.

Qué pedir

OFA/DNA CDDY (FGF4 retrogene) test on both parents.

1 source

Eyes

Brachycephalic ocular syndrome (entropion, pigmentary keratitis, corneal exposure)

MonitorInherente a la raza

The shortened muzzle and large, prominent eyes leave the cornea more exposed and prone to pigmentation and ulceration, and predispose to inward-rolling lower eyelids (entropion). A 2023 ophthalmic study of Shih Tzus from a single kennel found medial lower-eyelid entropion in 71% of the eyes examined.

Qué pedir

Annual eye examination by a board-certified veterinary ophthalmologist (OFA/CAER) on both parents.

2 sources

Breathing

Brachycephalic obstructive airway syndrome (BOAS)

SeriousInherente a la raza

Shih Tzus are extremely brachycephalic, with the same volume of soft tissue as a longer-muzzled dog crowded into a much shorter airway. A 2026 cross-sectional study assessed almost 900 dogs across 14 brachycephalic breeds, including Shih Tzu, using the functional grading test, and the Kennel Club responded by expanding free RFG testing at Crufts to Shih Tzu and 13 other breeds from 2026.

Qué pedir

The Kennel Club/University of Cambridge Respiratory Function Grading Scheme (RFGS) result on both parents.

2 sources

Kidneys & urinary

Juvenile renal dysplasia

Serious

Abnormally formed kidneys present from birth, found at unusually high rates in Shih Tzu kidney-biopsy series. Mildly affected dogs can appear normal for years while more severely affected puppies progress to kidney failure early in life, and standard bloodwork (BUN/creatinine) often misses it until most kidney function is already lost.

Qué pedir

No fully validated commercial DNA test exists yet. Ask for a renal ultrasound and urinalysis (including urine protein:creatinine ratio) on both parents, understanding these can still miss early-stage disease, and ask about kidney failure in close relatives.
