Best Shih Tzu Sweaters & Clothing in 2026: A Sizing-First Guide
The best Shih Tzu sweater is one sized for the breed's barrel chest and short back — a standard "small" often fits the chest but hangs past the tail. Shih Tzus typically need a chest girth of 16–20 inches with a back length of only 10–12 inches, which is exactly why generic small-dog sweaters bunch and slip on them.
Shih Tzu sweater sizing chart
| Weight | Chest girth | Back length | Size to buy |
|---|---|---|---|
| Under 9 lbs | 14–16 in | 9–10 in | S |
| 9–13 lbs | 16–18 in | 10–11 in | M |
| 13–16 lbs | 18–20 in | 11–12 in | L |
Measure the chest right behind the front legs — the widest point. If your Shih Tzu is between sizes, size up for the chest and roll the hem.
What actually matters in a Shih Tzu sweater
- Stretchy knit over stiff fleece — the barrel chest needs give.
- Wide neck opening — their head-to-neck ratio makes tight crewnecks a wrestling match.
- Low-friction underarm seams — Shih Tzu coats mat exactly where cheap seams rub.
- Harness slot if you walk in it.
When a Shih Tzu actually needs one
Despite the thick double coat, a freshly groomed "puppy cut" Shih Tzu loses most of its insulation — below roughly 45°F, a trimmed Shih Tzu benefits from a layer. Seniors and puppies feel cold sooner.
