At what age is a Shih Tzu considered a senior dog?

Most veterinary guidelines consider small dogs senior from around 9–10 years of age. Given the Shih Tzu's lifespan of 10–18 years, senior care may span a decade or more — twice-yearly vet visits from around age 8–9 onward are a wise investment.

Should I switch my senior Shih Tzu to senior dog food?

It depends on the individual dog. Senior formulas with lower calorie density and joint-supporting ingredients are appropriate for many dogs as they age and become less active. However, some healthy, active seniors do well on standard adult food. Discuss with your vet at routine check-ups, which should be twice yearly at this life stage.

My older Shih Tzu snores more than before. Is that concerning?

Some increase in snoring is common in aging brachycephalic dogs as soft tissues relax slightly with age. However, if breathing appears labored, your dog seems less able to exercise without breathing difficulty, or open-mouth breathing increases, a veterinary respiratory evaluation is warranted.
