How Much to Feed a Shih Tzu
The Shih Tzu's entire personality converges at the food bowl. Bred to sit in imperial laps rather than hunt or herd, this breed approaches eating with the same measured expectation it brings to daily life—and an uncanny ability to make you feel like you're the one missing out. Understanding how your Shih Tzu's temperament shapes its food needs is the key to feeding it well without creating a permanent beggar.

A Shih Tzu's modest size masks its gift for persuasion. This breed was designed for companionship, not endurance, which means its caloric needs are genuinely modest—the calculator above reflects this reality. But what matters more than the number is recognizing that your dog will watch you eat dinner with the intensity of a food critic, not out of hunger but out of social conviction that your plate is simply better. Shih Tzus thrive on routine and the security of knowing when food arrives, which actually works against the scavenging, grazing tendencies you might see in more independent breeds. Establish a feeding schedule and stick to it; your dog will respect the boundary because consistency feels like care to this breed.
The Shih Tzu's long coat is both blessing and challenge when it comes to monitoring weight. Those flowing hairs can hide weight gain effectively, which is dangerous for a small dog whose joints aren't built for extra load. Run your hands along the ribs regularly—you should feel them without pressing hard, and see a visible waist when viewed from above. Because Shih Tzus were bred to be lap ornaments, they're content with short walks and indoor living, which means the calories they consume matter more than they would in a more active breed. Overfeeding a Shih Tzu isn't a matter of a few pounds; it's the difference between nimble and stiff.
Treats are where the breed's charm becomes a liability. The Shih Tzu didn't evolve to say no to food offered by a loved one—that's not in its nature. You will be tested. The solution isn't to deny treats but to account for them honestly and to use small, valuable rewards (a piece of apple, a single training treat, a few seconds of play) rather than assuming your dog needs the same treat portions as larger breeds. Many Shih Tzu owners find that breaking regular treats into quarters works better than whole treats; the same reward satisfies the relationship without the caloric load. Your dog doesn't know it's eating a quarter treat—it knows you're giving it something, and that's what matters.
Frequently asked questions
How much food should a Shih Tzu eat per day?
A typical adult Shih Tzu weighing 12 lbs needs about 399 kcal per day (adult, neutered/spayed), which is roughly 105 grams — about 1.1 cups — of standard dry food, split into 2 meals.
How is the Shih Tzu's daily portion calculated?
We use the standard veterinary formula: Resting Energy Requirement (RER) = 70 × (weight in kg)^0.75, then multiply by a life-stage factor. For a 5.4 kg Shih Tzu, RER is 249 kcal, and the adult, neutered/spayed factor of 1.6 gives 399 kcal per day.
My Shih Tzu watches me cook and seems to beg constantly. Is it actually hungry?
Probably not. This breed was bred for companionship and attention-seeking, so begging is often a social behavior, not a hunger signal. If your dog is fed on schedule and has a healthy weight, the begging is your Shih Tzu's way of keeping you company and reminding you it exists. Ignoring the behavior is kinder than rewarding it, because feeding on demand can quickly lead to weight problems in a small dog with modest caloric needs.
Should I feed my Shih Tzu one meal a day or split it into two?
Most Shih Tzus do well on a consistent twice-daily feeding schedule, which helps maintain steady energy and supports good digestion. This breed doesn't have the metabolic needs of larger or more active dogs, but the predictability of two meals aligns with the Shih Tzu's preference for routine and structure. Feeding twice also makes it easier to notice if your dog's appetite changes, which is a useful health indicator.
How can I tell if my Shih Tzu is overweight under all that coat?
Feel for the ribs regularly—you should detect them with gentle pressure but not see them prominently. Look for a visible waist when your dog stands, and watch that the belly doesn't sag or drag. Shih Tzus are prone to spine and joint problems, so keeping weight in check protects their mobility as they age. If you're unsure, your vet can provide a body condition assessment.
