For double-coated breeds, the only maintenance their coats need in the summer is regular brushing and bathing, according to Dr. Reeder, so the hairs do not become matted and can continue to ventilate.
If your pup does not shed and has hair that is constantly growing, such as a poodle or bichon frise, you can feel free to give him a shorter summer cut to keep it from getting matted and easier to maintain.
“If there is excess matting of hair or medical needs, shaving is ideal,” Dr. Reeder says. “Most of our pets are indoors and thus do not require full-coat shaving. I recommend to not shave below a medium-hair coat length and have a professional groomer shave the pet.”
