Dog hypothermia (dangerously cold)
A dog that is shivering hard, weak, stiff, or unusually quiet after cold or wet exposure may be developing hypothermia, and as it worsens shivering can stop and the dog becomes very sluggish, cold, and unresponsive — a serious emergency. Move your dog somewhere warm and dry, wrap them in blankets (with a warm, not hot, covered bottle against the body if available), and contact a veterinarian, especially for puppies, small, thin, or elderly dogs. Warm gradually; do not use very hot water or direct heat, which can harm cold skin.
Go to a vet now if
- Severe weakness, stiffness, or collapse after cold or wet exposure
- Shivering that has stopped while the dog stays very cold and dull
- Cold body, pale or grey gums, or slow breathing
- A puppy or small dog that is cold and limp
Call a vet today if
- Mild shivering that stops quickly once your dog is warm and dry, and they are otherwise normal
What to tell the vet
- How long your dog was cold or wet
- Whether shivering, weak, or unresponsive
- What warming you have started
- Gum colour and breathing
- Your dog's age, size, and coat
- Any conditions or medications
What not to do
- Do not use very hot water, hair dryers, or direct heat on cold skin
- Do not rub the limbs vigorously — warm the core gradually
- Do not delay the vet call for a weak, very cold, or unresponsive dog
What your vet may check
Your vet will measure body temperature, warm your dog safely, support circulation, and check for complications. Severe hypothermia needs careful, monitored rewarming.
Recovery support after veterinary assessment
As your dog recovers, keep them warm and dry and follow your vet's advice. Supportive nutrition and hydration during recovery are used on veterinary advice once your dog is stable.
Frequently asked questions
What are the signs of hypothermia in dogs?
Early signs are shivering, weakness, and stiffness. As it worsens, shivering stops and the dog becomes very cold, dull, and slow to respond — a serious emergency.
How do I warm a cold dog safely?
Move them somewhere warm and dry, wrap in blankets, and use a warm (not hot) covered bottle against the body. Warm gradually and avoid direct or intense heat, then call your vet.
Which dogs are most at risk of getting too cold?
Puppies, small, thin, short-coated, and elderly dogs, and those that get wet in cold weather, lose heat fastest and are most at risk.
