A heartwarming video of a golden retriever enjoying the snow in Pennsylvania has gone viral, prompting a discussion about cold weather safety for dogs. While the video is delightful, it highlights the importance of understanding that not all dogs are equally tolerant of cold temperatures. Vets Now emphasizes that a dog's size, breed, coat, age, and health all play a role in their ability to withstand the cold. Temperatures above 45°F (7°C) are generally safe, but caution is advised between 34°F (1°C) and 25°F (-4°C) for vulnerable dogs. Below 25°F (-4°C), the risk of hypothermia and frostbite increases significantly, especially if the dog is wet.
