Brittanys are hardy field dogs, but they are not built like a Newfoundland. Their coat is flat or slightly wavy, moderately dense, with light feathering and far less undercoat than many sporting breeds, and they carry very little body fat. That combination means a Brittany that is running hard stays warm, while a Brittany standing still, soaking wet or elderly can chill quickly. Choosing the right winter coat for this breed means thinking about activity, water and visibility, not just temperature.

When does a Brittany need a coat?
A healthy adult Brittany out for an active walk usually manages well down to around 20-25°F. A coat becomes useful in several situations: temperatures below about 20°F, wind chill, freezing rain, long periods standing still (such as waiting at a hunt stand or on the sidelines of a field trial), after retrieving from cold water, and for puppies, seniors and dogs with thyroid problems or low body weight. Shivering, lifting paws, hunching and slowing down are signs your dog is cold.

Fitting a Brittany coat
Measure from the base of the neck to the base of the tail (or where the tail would be for a bob-tailed dog) for back length; most adults measure 17-21 inches. Measure the deepest part of the chest, typically 22-28 inches. Brittanys have a deep chest and a tuck-up at the waist, so coats with adjustable belly straps fit better than stretchy tubes. Check that the coat does not press on the shoulder joints or rub the armpits during a full gallop.
Field vests vs pet coats
For hunting days
Upland hunters often put a lightweight blaze orange vest on their Brittany. It adds almost no warmth but makes the dog visible in cover and protects the chest from briars. For waterfowl work or wet, cold days, a neoprene vest traps a layer of warm water against the body and adds buoyancy. Remove neoprene once the dog is back in the vehicle so it can dry.
For everyday walks
A lightly insulated, waterproof jacket with a fleece lining and reflective trim is ideal for dark winter mornings. Choose a coat with a leash port so you can use a harness underneath.
Keeping the coat and skin healthy
- Dry the dog thoroughly after wet outings before it rests; damp coat against the skin encourages hot spots.
- Check the armpits and the area under straps for rubbing or matting after long use.
- Remove snowballs from the leg feathering and between toes after snowy walks.
- Do not leave a coat on indoors; Brittanys overheat quickly once they are moving around the house.
Health notes
Brittanys can be prone to hypothyroidism, which often makes dogs more sensitive to cold, lower in energy and prone to weight gain. If your once-hardy dog suddenly seeks warmth constantly, ask your vet about a thyroid check rather than simply adding layers.
Snow, ice and the Brittany’s feathering
Although the Brittany coat is fairly short on the body, the light feathering on the legs, belly and ears collects ice balls in wet snow. A coat that covers the belly helps, but the legs usually stay bare, so trim the hair on the back of the legs and between the toes a little shorter in winter. After outings, thaw ice balls with lukewarm water rather than pulling them out, then towel dry. Puppies under six months and seniors over ten lose heat quickly, so shorten their cold-weather sessions even when they are wearing a coat.
FAQ
Do Brittanys need winter coats?
Not always. Active adults tolerate moderate cold well, but coats help below around 20°F, in wind and rain, after cold-water work and for puppies and seniors.
Should my hunting Brittany wear a neoprene vest?
For waterfowl and wet, cold conditions, yes; it reduces heat loss and adds buoyancy. For dry upland hunting, a blaze orange vest for visibility is usually enough.
Bottom line
The best winter coat for a Brittany depends on the job: a neoprene vest for cold-water days, a blaze orange vest for visibility in the uplands, and a light insulated, waterproof jacket for everyday winter walks. Fit it to the deep chest, keep the shoulders free and dry your dog properly afterward.
