Shih Tzu profileThe Shih Tzu is a medium-sized Toy dog originally from Tibet / China, typically weighing 4–7 kg with a double-coated coat. Being a laid-back, flat-faced dog, a Shih Tzu needs a jacket matched to its actual build and coat — not a one-size-fits-all pick. This guide covers what to look for in a jacket for a Shih Tzu, then links filtered picks that match the breed's frame.
Yes — the Shih Tzu genuinely needs a coat for Irish winter walks. Short-coated, small or brachycephalic breeds lose body heat fast, and a wet, cold dog is a stressed dog.
What to look for in a Shih Tzu jacket
- Insulated + waterproof outer shell. Irish weather isn't just cold, it's wet. A coat that gets soaked makes the dog colder than no coat.
- Belly coverage — body heat escapes fastest from the underside; coats that wrap underneath keep more warmth in.
- Reflective trim — combined with reflective collar/harness, this is your dog's "visibility kit" for dark winter walks.
- Machine washable. Muddy walks mean weekly washes.
- Measure your dog — across the back (neck base to tail base) is the canonical sizing. Brand sizes vary wildly.

When to put the coat on
Rough rules of thumb for the Shih Tzu: under 10 °C + wet → coat on; under 5 °C → coat on regardless; over 12 °C → no coat unless old or sick. Watch for shivering — that's the unambiguous signal you waited too long.
Jacket for a Shih Tzu: common questions
What size jacket does a Shih Tzu need?
Shih Tzus typically weigh 4–7 kg, which puts them in the medium-sized range, so start with a jacket sized for that band. Sizing varies between brands and individual Shih Tzus differ, so measure your own dog and check the maker's size chart before buying.
What should I look for in a jacket for a Shih Tzu?
The Shih Tzu is a laid-back breed, so comfort and easy cleaning usually matter more than heavy-duty ruggedness when choosing a jacket. Above all, match the jacket to this breed's actual build rather than buying generic.
Do flat-faced Shih Tzus need a special jacket?
Yes. Shih Tzus are brachycephalic (flat-faced), which affects breathing and eating, so choose a jacket that avoids pressure on the airway and suits a short-muzzled dog.
