Is It Good to Cut Your Dog’s Hair in the Summer? Expert Advice

Shaving your dog’s coat in summer can harm their natural cooling system—learn why preserving fur is key to keeping pups safe and comfortable in the heat.

Many dog owners assume that giving their pup a short summer haircut is the best way to beat the heat. After all, we shed our winter layers when temperatures rise—shouldn’t dogs do the same? Actually, this well-intentioned idea can backfire. A dog’s coat is far more than just fur; it’s a sophisticated temperature-regulation system that often works best when left intact.

Dogs rely on their coats for more than warmth. That double-layered fur acts as insulation against both cold and heat, trapping cool air close to the skin in summer while shielding them from harmful UV rays. Shaving it away disrupts this natural thermostat, leaving them vulnerable to overheating and sunburn. Ever noticed how desert animals like camels have thick coats? There’s a reason—their fur deflects heat rather than absorbing it.

Some breeds face greater risks than others. Northern varieties like Huskies or Malamutes have undercoats designed to self-regulate, and cutting them can trigger irreversible texture changes. Short-haired dogs, ironically, may benefit from *light* trimming since their coats lack insulating layers. But even then, sun protection becomes critical—imagine lounging poolside without sunscreen, and you’ll grasp why vets warn against exposing pink skin beneath a shaved coat.

So what’s the alternative? Focus on strategic grooming. Regular brushing removes dead undercoat (a major cause of overheating), while a slight trim around paw pads and belly improves airflow. Cooling mats, hydration breaks, and shaded walks during cooler hours work wonders. If you’ve ever seen a dog panting in the shade post-shave, that’s their body struggling to compensate for lost temperature control—a sign their coat was doing its job all along.

Ultimately, summer grooming isn’t one-size-fits-all. Observe your dog: Are they seeking cool surfaces? Panting excessively? Those are better cues than the calendar. When in doubt, consult your groomer or vet—because keeping your best friend comfortable starts with understanding what their fur truly does for them.
