About the Shih Tzu
The Shih Tzu is a small, affectionate companion breed with ancient roots in China, where they were treasured as palace dogs. Known for their flowing double coat, short snout, and large expressive eyes, Shih Tzus are gentle, outgoing, and surprisingly playful despite their toy breed size.
Shih Tzus are brachycephalic (flat-faced) dogs, which means they can be prone to respiratory issues. They adapt well to apartment living and don't require intense exercise, but regular moderate activity is important to keep them fit and mentally stimulated.
While Shih Tzus are not as food-obsessed as some breeds, weight management is still important. Obesity worsens their breathing difficulties and strains their small joints and spine. Their dense coat can also hide extra weight, making regular weigh-ins essential.
Keeping Your Shih Tzu at a Healthy Weight
- Feed measured portions twice daily and avoid table scraps.
- Provide 20–30 minutes of gentle exercise daily — short walks and indoor play are fine.
- Avoid heat and humidity during outdoor activities due to their flat-faced airway.
- Use small, low-calorie treats to avoid adding excess calories.
- Weigh monthly and track trends over time rather than focusing on single weigh-ins.
- Brush the coat regularly to check for hidden weight changes under the thick fur.
