Is my dog cold? Recognise signs and choose the right coat

Not every dog needs a coat, but fur does not automatically protect against wet, cold weather. Size, age, health, undercoat, wind and activity all play a part.

Small dogs lose more heat relative to their body mass. Puppies, seniors, very lean dogs and animals with illnesses or little undercoat are also more sensitive. Short or thin fur, a low belly and wet weather can speed up heat loss. A healthy, active dog with a dense undercoat often manages normal winter walks without extra clothing.

There is no temperature threshold that suits all dogs. Wind, moisture, duration and movement significantly change the demands. A dog walking briskly produces more heat than one waiting at a bus stop for a long time.

Trembling can also result from fear, pain, nausea or neurological problems. If a dog often seems cold indoors or without an obvious cold stimulus, this should be assessed by a vet.

A functional coat can help small, short-haired, elderly, sick or recently operated dogs. It should protect the back and body, repel water in wet, cold weather and not restrict movement. A good fit matters:

Remove wet clothing after the walk and dry your dog. A thick coat can become too warm during vigorous play. Watch for panting, a slower pace and a desire to lie down too.

More food is not automatically the right answer on cold days. Many indoor dogs move less in winter and need the same number of calories or even fewer. Only dogs that are regularly active outdoors for long periods may have higher energy needs. Weight trends and body condition are decisive.

Weigh your dog regularly and feel the ribs. They should be easy to feel without protruding strongly. Adjust the diet according to an observable trend rather than daily impressions of the weather.

Note: severe weakness, slow breathing, confusion or collapse after cold exposure may indicate hypothermia and are an emergency.
