Dog owners, listen up: Be sure to give your pooch the right type of haircut for their breed. You may be burning up in the hot summer months, but cutting your dog's fur too short to help them cool off can actually do more harm than good. Dogs that naturally have long, thick fur have it on purpose; it helps block harmful UV rays from giving their skin heat and sun burns. And in the winter months, letting the coat get too long can actually cause them to overheat, even if the temperatures outside would suggest otherwise. Rule of thumb: Ask the groomer to recommend the right level of grooming to make sure your best friend is comfortable and protected.
