Is hot asphalt really dangerous to pets? Asphalt can get very hot in the sun and burn your pet’s paws. Dogs seem so sturdy and it’s easy to assume they’re more resistant to the elements than we humans are. By now, most people know not to leave their dog in the car on a sunshiny day and to be alert for signs of heat stroke, but it’s easy to forget about the pavement. Asphalt in the sun gets extremely hot and can give burns that must be treated by a veterinarian. Put the back of your hand on the pavement. If you can’t keep it there for at least five seconds, it’s too hot for your pet to walk on. On hot days, try to plan so you walk your dog in the morning or evening when the pavement is cooler. Or stay on grass, and limit the outside time. If there are no other alternatives to walking on the asphalt, there are special dog booties that can protect the sensitive paws from heat.
