Short answer: plenty of dogs around Alpharetta never need a coat, but small, short-coated, lean, very young, senior and thin dogs do on cold mornings. A good rule of thumb: if you want a jacket for the walk, a little dog in a thin coat probably does too. When the wind chill drops below 20°F, keep outdoor time short for every dog.
Georgia winters have a reputation for being mild, and on average they are. Averages hide the mornings, though, and the morning walk is when most dogs are outside. Here's how to tell whether your dog needs a layer, which kind, and how to get the fit right.
How cold does it actually get here?
Atlanta's average January temperature is about 45°F, and this past January ran right on that average. It still dropped to 14°F on January 27, according to the National Weather Service. An average of 45 means plenty of walks in the 20s and 30s before the sun gets going, often with damp air and wind that make it feel colder.
Dogs that do better with a coat
The American Kennel Club lists the dogs most likely to need help staying warm:
- Small and toy breeds, which lose body heat fast
- Lean, short-coated dogs such as greyhounds, whippets, vizslas and German shorthaired pointers
- Dogs built low to the ground, like dachshunds, basset hounds and corgis, whose bellies sit close to cold, wet grass
- Hairless dogs and dogs with clipped or shaved coats, including poodles and any dog fresh from a short trim
- Puppies and seniors, whatever the breed
- Dogs with arthritis, heart disease or a low body weight
Dogs that usually don't
Big dogs with thick double coats, such as huskies, malamutes, Bernese mountain dogs, Saint Bernards and Newfoundlands, are built for far colder weather than ours. For them, overheating on a 60-degree January afternoon is the more likely problem. A healthy adult dog with a medium or thick coat is usually fine; as the AKC's veterinary adviser puts it, if people can enjoy the weather with proper outerwear, most dogs can be outside too.
Signs your dog is cold
Shivering is the first sign of hypothermia, and it means it's time to head inside and warm up (Vermont Public, citing a Petplan veterinarian). Other clues: lifting one paw and then another, a hunched back with the tail tucked, slowing down, or turning for home halfway through the usual loop.
Picking the right layer for a Georgia winter
Most of a Georgia winter calls for a light layer, not an Alaskan parka. Here's how the options compare.
Puffer vests: the everyday pick
A sleeveless puffer adds insulation without restricting the legs, and it comes off fast once the sun is out. Gooby's puffer vests are $29.99 and sized for small dogs, from XS (3 to 5 lb) to XL (20 to 25 lb), in red, turquoise, pink, purple and orange. For bigger dogs, the Hooded Puffer Dog Vest ($49.99) runs from Large (25 to 38 lb) to XXL (50 to 70 lb) in aqua, red and pink.
Fleece: warm without the bulk
Fleece is the right weight for most of our winter: warm on a 40-degree morning and not stifling by mid-afternoon. The Worthy Dog's Purple Plaid Fleece Zip Dog Vest ($44.99 to $49.99) zips on instead of pulling over the head, and its sizes run all the way to large breeds of more than 100 pounds.
Sweaters: for cool mornings and chilly houses
A knit sweater is the cozy option for dry, cool days. The Green Fair Isle Dog Sweater from The Worthy Dog ($39.99) buttons along the back, so there's no wrestling it over the head, and the Red Buffalo Check Dog Sweater ($39.99) doubles as the holiday-photo outfit. Knits soak up rain, so save them for dry weather.
Raincoats: for the cold, wet days
Wet fur loses much of its insulation, which makes a cold rain harder on a short-coated dog than a dry, cold morning. Cycle Dog's hooded raincoats come in S/M ($59.99) and L/XL ($79.99), sized by back length, chest and neck. A raincoat also cuts down on the towel-drying when you get home.
Faux fur coats: for the coldest mornings
For a tiny or shivery dog on a 20-degree morning, the Leopard Reversible Faux Fur Dog Coat from The Worthy Dog ($49.99) has faux fur on one side and a quilted finish on the other, so it's two coats in one. It comes in XS (6 to 8 lb) through XXL (50 to 70 lb).

Getting the fit right
Weight ranges are a starting point, not the whole story. Measure three things with a soft tape: back length, from the base of the neck to the base of the tail; chest, around the widest part just behind the front legs; and neck. Our guide to measuring your dog for a jacket or coat walks through each one.
Once it's on, your dog should be able to walk, run and sit comfortably, and the coat shouldn't be so loose that a leg can get tangled in it. You should be able to slide two fingers under the straps. Wash coats regularly, and let them dry completely before you put them away: the AKC's veterinary adviser notes that a coat stored damp can harbor bacteria that irritate the skin.
Cold-morning walk tips
- Keep it short when it's bitter. When the wind chill is below 20°F, the AKC suggests 15 to 20 minutes outside and then a warm-up indoors.
- Shift the walk a little later. An hour after sunrise can be several degrees warmer than first light.
- Towel off after wet walks. Dry the belly and paws, especially on low-slung dogs.
- Take the coat off indoors. A coat is for outside; most dogs overheat in one by the fireplace.
- Watch the paws. On the rare icy morning, rinse paws after walking on treated sidewalks.
FAQ
Do dogs need coats in Georgia?
Some do. Small, short-coated, lean, very young, senior and thin dogs benefit from a coat on cold Georgia mornings, while big dogs with thick double coats usually don't need one.
What temperature is too cold to walk a dog?
When the wind chill drops below 20°F, the American Kennel Club suggests keeping outdoor time to 15 to 20 minutes and then warming up indoors. Small and short-coated dogs feel the cold sooner, so watch for shivering.
Should my dog wear a coat indoors?
No. Take the coat off once you're inside so your dog doesn't overheat. A sweater can stay on in a chilly house if your dog seems comfortable in it.
How do I measure my dog for a coat?
Measure back length from the base of the neck to the base of the tail, chest around the widest part behind the front legs, and the neck. Compare all three with the size chart rather than going by weight alone.
