A Scottish Terrier in Long Island, New York, became an internet sensation after a video showed her fur freezing during a winter walk. The dog's owner posted the video on Instagram, where viewers watched as she meticulously removed icy clumps from the patient pup's fur. Experts explain that these clumps form when snow melts on the dog's warm fur and subsequently refreezes in the cold air. While not immediately dangerous, this icy buildup can cause discomfort and potentially increase the risk of frostbite if not addressed.
