To those who have long-haired cats or dogs and are considering shaving your pet’s coat for the summer to help him “cool down”, DON’T DO IT! Although dogs and cats only have sweat glands on their footpads (hence why they can leave footprints all over a shiny wood floor if stressed out or overly excited), they have their own super-effective way to cool down. Cats lick their fur and paws, and when the saliva evaporates, it cools them down; dogs keep themselves cool by vaporizing large amounts of water from their lungs and airways when they pant, expelling body heat in the process.
Although they have a warm thick double coat, long-haired cats and dogs are actually kept COOL from this. The coat acts as insulation against the sun’s UV rays and its effects. It regulates the animal’s body temperature, so when it’s hot, it keeps the cool in, and when it’s cold, it keeps the warm in. Shaving your pet’s fur off is like removing the walls of your home and then wondering why it’s scorching hot even though the AC’s on or freezing cold even though the heat’s on.
The best way to keep your pet cool is to keep your pet’s coat mat-free, well-brushed, and clean. Dogs have almost no pigment in their skin to ward off harmful UV rays and are very prone to sunburn and skin cancer, so the best way to protect your dog is to save the longer walks for evenings, and consider applying pet-specific sun block to thinly covered areas, such as the bridge of your dog’s nose, the tips of his ears, and his belly. You can also use a FURminator (or an off brand brush that does the same thing) to keep tangles to a minimum, remove loose fur, and lighten the coat a little bit. Keeping the coat healthy is the first and easiest step to keeping your pet cool in the Summer heat!
If you feel that you HAVE to give your cat or dog a trim, try to leave at least two inches of fur to protect your pet from the elements. Be aware that once shaved, a double-coated pet’s coat will never grow back the same. It can end up patchy, discolored, thinner, and will shed even more than before! The rough top coat may never grow back as well, and your pet’s natural defenses from heat and cold will be gone for the rest of its life.
For dogs who want to play in the back yard, be sure to provide lots of shade, water, and breaks, even if your dog’s eager to keep playing; your dog probably doesn’t know what heat stroke is, but when it happens, you’re going to have a very big vet bill all because Fido wanted to play Frisbee for ten more minutes.
Hopefully this helps, and your pets keep cool in this Summer blaze. Remember that the moment you start to feel thirsty and gross, your pet may be too! Be sure to offer lots of water (and pee breaks) and keep that coat healthy and non-shaven!
