The Flat-Coated Retriever is borderline — coats are a "nice to have" for wet days but not essential for short walks unless the temperature drops below 5 °C.
What to look for in a Flat-Coated Retriever jacket
- Medium-weight padded coat — enough to block wind + rain, not so heavy that the dog overheats on a brisk walk.
- 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 Flat-Coated Retriever: 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.
