What’s Up Doc? by Beth Rodgers

he temperatures are soaring, and we humans are running for pools, iced drinks, or whatever else brings us relief from the heat. Surely your fluffball golden must be miserable under all that fur! Time for the “summer cut” and let’s get rid of that extra hair so the poor thing can cool off, right? WRONG!! No, never, don’t even think about it, and no way. Big no-no as a matter of routine to shave your dog for summer. You mean leave all that fur on? Absolutely! We often refer to the dog’s fur as a “coat,” but that contributes to a misunderstanding of how the dog’s fur really works. Of course wearing a coat in summer the poor thing must be dreadfully warm! So let’s dispense with the word coat for this discussion. Instead, let’s think of the fur in terms of what it does, and that involves its functions for insulation and protection. As you know with a house, insulation is important to keep temperatures stable. You set a desired temperature on your thermostat, and the heat and air conditioning systems work to create and maintain that temperature. The insulation helps to separate the inside of your house from the outside so it is easier to get the temperature to stay where you set the thermostat. Take away the insulation, and your mechanical systems are going to have a heck of a time keeping your house at the temperature you desire. The inside will always want to match the outside if there is a poor barrier between the two.

Don’t Shave That Golden!
The insulation function of a dog’s fur works in the same way. Dogs have a core body temperature that they must maintain for the organs to function well. Generally this is in the vicinity of 100 to 102 degrees or so, give or take. The fur is what protects them from external stimuli that can cause that temperature to be harder to maintain. Without the fur as insulation, the heat gets in more easily and the body has to work that much harder to keep things stable. Imagine shaving your head and being outside in the summer. Would it be cooler without that hair? Quite the contrary. You not only will feel the sun’s rays more intensely but you will be more subject to injury. OK, so you’re not shaving the dog down to the skin, so that isn’t a fair comparison, you might say. The physics are still the same. The sun and the heat can more easily affect the dog because the fur is not there as insulation to protect the dog from the external environment. Even if the temperature outside is lower than the dog’s body temperature, the sun and all the other environmental characteristics are now acting more directly on the dog because there isn’t that important layer of fur to insulate the skin. Dogs can get sunburned, and you may recall a time when you were outside in 90 degree weather, feeling the sun on your skin and thinking it felt a lot warmer than 90 degrees! Add to that experience the heat of pavement or a patio which are well over the ambient air temperature, and things can become dangerous quickly without some

insulation or protection. A temperature of 90 degrees is barely suitable for a warm bath. But the sun hitting your skin with a 90 degree air temperature, or maybe more if you are near reflective or heat-absorbing surfaces? You will feel that! So will your dog, and it can be dangerous, especially for a dog without it’s normal protective layer of fur. Dogs like our goldens are designed well for maintaining a healthy body temperature. As double-coated animals, they lose their undercoat as the seasons change to warmer months. This loss of undercoat adjusts the insulation for them automatically. In the winter, they grow that back to provide more protection against the cold. You may have noticed how it can be snowing or sleeting like crazy and in spite of that 100 degree body temperature, the snow does not melt when it lands on your dog’s fur. That fur is doing a great job keeping that body heat regulated. Mess with their fur by shaving them and you have disrupted that crucial thermoregulatory mechanism, which is a fancy way of saying the dog’s ability to maintain the temperature essential for life. Thermoregulation. It comes built in to the dog and includes their fur as a crucial component. So do not shave your dog. Fur also serves another purpose, and that is protection from physical elements. Fur provides an additional layer of protection against injury to the skin such as might occur from a good roll in the grass. The topcoat, which is what
