The reason most dog grooming professionals suggest you do continue cutting your dog’s hair in the winter is that many dog parents fail to regularly brush their fur, which results in serious matting come spring. If you are worried that your fur-baby will get cold with short hair, then invest in winter gear, such as doggie coats. Often, this is a simple mistake based on good intentions, such as thinking they should allow their dog’s coat to grow during the winter to give him extra warmth. In actuality, winter dog grooming is just as important, possibly even more so, than it is during the summer months. Long, wet, matted hair easily makes a cold, wet, and infection-susceptible dog. What you may think is adding extra cold-weather protection will actually be doing just the opposite. Hill explains, Fur that’s matted doesn’t insulate or provide warmth; instead, it provides discomfort, pain, and hot spots. Do Continue Haircuts Whether you choose to keep cutting your dog’s hair throughout the winter, opt for a longer trim, or let it grow, it is important to continue brushing and shampooing it regularly.
