Cold weather poses serious health risks to dogs, especially those exposed for extended periods. Frostbite can lead to permanent tissue damage, while hypothermia may result in life-threatening complications such as organ failure. Dogs with thin coats, small breeds, puppies, and older or ill dogs are particularly vulnerable. Wet fur and wind exacerbate these risks, and frostbite symptoms may take days to fully appear. Owners should monitor their pets closely and seek veterinary care immediately for any concerning signs. Source time: not specified.
