Jess Rona sighed deeply after I told her I had recently gotten my six-year-old Poodle mix her annual “summer cut.” Shaving down my dog’s dense, curly hair each summer was essential for helping her cope with the brutal Texas heat, I figured, like removing a heavy winter jacket that she didn’t need anymore. Once it cooled down again, I explained, I would put the figurative jacket back on by letting her coat grow back in.

“It is a misconception that you need to shave your dog in the summer and grow their coat in the winter,” she said politely. The owner of LA’s Jess Rona Grooming, whose clients include Katy Perry and Zooey Deschanel’s dogs, assured me I’m not alone in my misunderstanding: “I have this conversation every summer and every winter with my clients.” Below, Rona takes us through what you need to know about seasonal grooming.

Think of your dog’s coat as insulation.

Don’t think of dog’s coat like a sweater, Rona adds, but rather, like the insulation of a home. “You don’t need a ton of coat, but you need a little bit to protect them against the elements.” Each strand of hair on a dog has follicular muscles that help move the hair around so that a dog can regulate their body temperature. “When you take their coat off, they have nothing to protect them,” she says, explaining that a completely shaved dog is more susceptible to things like a sunburn or a tick attaching itself to the dog’s skin. 

Rona also adds that shaving doesn’t help with shedding, since shedding happens at the root, and has nothing to do with the length of a dog’s hair. “It’s not like you’re hurting your dog by shaving them,” she adds. “There are benefits: If your dog goes swimming all the time, is really active, or gets matted really easily, sure — keep it short. But don’t do it because you think it will cool your dog off.”

Some breeds need extra grooming in the summer.

While you don’t need to shave down your dog to beat the heat, Rona adds that double-coated dogs — breeds like Huskies, Labradors, Newfoundlands, Pomeranians, and Australian Shepherds that have a dense, fuzzy, short undercoat that helps regulate their temperature as well as a thicker, wirier, and longer top coat that helps repel moisture and dirt — benefit from regular grooming during the hot summer months.

“If you do have a double-coated dog, I definitely do recommend getting a professional bath monthly during the summer,” she says. What happens, Rona explains, is that the dense undercoat of a double-coated dog gets packed in if it’s not brushed out regularly, and then the skin can’t breathe as easily. “So that will cool your dog off if you can get the undercoat out,” she says, adding that groomers have fancy force-dryers that blow out all the undercoat in a way that is painless for your dog, and doesn’t require hours and hours of dedicated brushing. (It’s also a fairly messy procedure that you might not want to do too often at home: “It looks like it’s snowing in the grooming room,” she says with a laugh. “It’s just fluff everywhere.”)

Add an actual coat in the winter. 

While dogs’ coats do serve as insulation, sometimes icy winter temperatures call for a little extra padding in the form of sweaters and boots. According to the ASPCA, this is especially important for short-haired dogs, who should have a high-necked sweater or jacket that covers them from their neck down to their tail, and around their stomach. For long-haired dogs, the organization recommends a small trim to prevent ice from clinging to their coats and forming icicles, as well as washing and cleaning off your pet’s paws after a walk to remove any ice or salt. 

Overall, Rona concludes, regular groomings are important throughout the year because they help maintain a dog’s health and comfort. And while shaving your dog down won’t do them harm, don’t feel the need to do it unless it’s for aesthetic reasons. “As far as seasonal cuts go, you don’t have to keep your dog’s coat short in the summer and long in the winter,” Rona concludes. “Unless you like the look of it!”
