A long senior chapter, visited twice a year
A senior Shih Tzu should see the vet every six months, twice a year, where a healthy younger adult Shih Tzu is typically checked once a year. With lifespans frequently reaching the mid-teens, a Shih Tzu may spend five or six years as a senior, longer than many big breeds live in total. That long chapter argues for the shorter interval on its own: more years of ageing means more years in which eyes, teeth, skin, and breathing can drift, and six-month visits turn that drift into a series of small, manageable corrections instead of one accumulated list.
The eyes lead the Shih Tzu list
Shih Tzu eyes sit prominent in shallow sockets under a flat face, and age adds dryness, cloudiness, and slower healing to eyes already exposed to the world. A twice-yearly look lets the vet check tear production, lens clarity, and the corneas before a scratchy, under-lubricated eye becomes a painful one. Breathing deserves the same rhythm, since the breed's short muzzle makes airways less forgiving as tissues relax with age and any weight gain presses in. Teeth in a small, crowded Shih Tzu mouth commonly need attention by the senior years, ears under heavy ear hair collect trouble quietly, and skin beneath a long coat can hide irritation or lumps from a quick glance.
What to ask for at each six-month visit
Request an eye check that goes beyond a glance, including a comment on tear wetness and lens clarity recorded in the notes, plus a breathing assessment while your Shih Tzu is calm and cool. Have the mouth examined properly, ears looked into rather than at, and the coat parted so skin and any lumps are felt as well as seen. Senior blood screening builds baselines for the years ahead. Bring your own Shih Tzu specifics: how sleep breathing sounds now, whether face-wiping and eye-pawing have increased, how walks have shortened, and whether grooming tolerance has changed, since a dog who suddenly hates the brush may be reporting sore skin or joints.
Eye and breathing signs that cannot wait
A Shih Tzu who squints, paws at one eye, or shows a cloudy or blue-looking patch on the eye surface should be seen the same day, because prominent eyes deteriorate fast. Noisy breathing that appears at rest, open-mouth breathing in a cool room, or a collapse in warm weather is likewise urgent. Book promptly for appetite loss beyond a day, red or smelly ears with head shaking, a new lump under the coat, or a companion dog who stops trotting to greet you. In a breed whose main vulnerabilities sit on the face, facial changes are the early-warning system, and six-month routine visits are no substitute for acting on them.
Records for a dog who ages slowly
Because a Shih Tzu's senior years stretch out, her file becomes a genuine long-term document: eye notes from three years ago explain today's lens, and last year's breathing note settles whether this year's snore is new. That continuity is easy to lose across a long life and several groomers, clinics, or house moves. KinsLe's Pet Passport keeps a senior Shih Tzu's records in one portable packet, so the vet in front of her always has the years behind her.
