Some pets are built for winter; others were clearly designed for the sofa. Cats and small dogs lose body heat quickly in cold weather, and a well-chosen sweater can make a real difference for the ones that feel the chill. This guide starts with cats, then covers dogs, and finishes with fitting, care, and sizing so you can choose with confidence.
Does Your Pet Actually Get Cold?
Weight and coat matter more than age. A shivering Chihuahua, Whippet, or Sphynx cat will feel the cold long before a fluffy Samoyed does. As a rule of thumb: if the temperature is below 7°C (45°F) and your pet is small, short-haired, hairless, or lean, they will benefit from an extra layer on outings.
Signs a pet is cold include shivering, lifting paws off the ground, curling into a tight ball, and hesitating at the door. If you see any of these, warm up and shorten the outing — no sweater replaces a sensible walk length.
Choosing a Sweater for a Cat
Most healthy indoor cats never need clothing, and that is perfectly normal. The exceptions are hairless breeds like the Sphynx, very young or elderly cats, and short supervised trips outdoors in cold weather.
Cats have shorter backs and far more flexible bodies than dogs, so choose cat-specific pieces that do not restrict jumping, climbing, or grooming. A lightweight knit such as our red and white knit sweater, sized for a cat's shorter back, is far kinder than a piece borrowed from a dog. Browse the full range of cat sweaters to compare shapes and measurements.
If your cat freezes, rolls, or hisses when dressed, respect that — clothing is never worth their stress.
Choosing Winter Clothing for a Dog
Small dogs, and short-haired or lean breeds, feel the cold first. A knit sweater is the daily staple: look for a gentle ribbed collar and a snug (never tight) chest fit that traps a layer of warm air while still allowing movement. Our yellow bee knit sweater is cut for small dogs and works for mild to moderate cold and indoor warmth needs.
Whatever you choose, it should cover the chest and belly — the areas that lose the most heat — and have leg openings that let a dog trot and squat naturally. See the rest of our dog clothes for sizes and fits. For genuinely cold or wet days, some owners layer a generic, well-fitted coat with a water-resistant outer shell over a sweater; that is general advice rather than one of our pieces, so always check any coat's own measurements before buying.
How to Check Fit and Comfort
- You can slip two fingers between the fabric and your pet's back
- Chest and neck never squeeze; movement stays natural
- Remove clothing indoors and before sleeping or grooming
- Machine-wash knits regularly — damp, matted sweaters trap cold instead of warmth
- Always supervise first wearings and watch for rubbing or discomfort
How to Care for Pet Sweaters
Knit sweaters are worn close to the skin and pick up oils, dirt, and loose fur quickly, so machine-wash them regularly — a damp or matted sweater traps cold instead of warmth and can rub against the coat. Check the care label on each piece, use a gentle cycle, and air-dry flat rather than tumble-drying. Store knits folded, not hung, so the shoulders keep their shape between seasons.
How to Choose the Right Size
Sizing is the difference between a sweater your pet forgets they are wearing and one they fight. Measure the back length, chest girth, and neck, then match those numbers against our pet clothing size guide before ordering.
