Some dogs have a great coat to keep them warm in the winter and other dogs don't. So how how long can they endure the cold? You need to look for signs and recognizing when it's time to go home.
First Signs of a cold dog.
1. Ice between their toes or on their body
2. Dog is shaking or shivering due to wetness, cold or both.
If you don't take action early your dog will have blisters and/or swelling as well as some frostbite.
Second Degree
Second degree frostbite will result in skin blisters. Skin turns a very pale/gray colour on their ears, feet,toes and tails.
Third Degree
Third degree may result in gangrene resulting in amputation of affection area and sometimes death.
Dogs like Charlie have a double-coated fur to protect him from the cold weather and wet weather but they too have their limits. If you have a hairless dog, a dog with little fur, or you live, walk and run in a very cold climate, I recommend a coat made for your dog. You can also buy boots for your dog as well.
Always monitor your pet. Keep them safe. They rely on your judgement.
