When the temperature outside is over 80 degrees it’s causes the pavement to become very hot.
Please take the time to put your hands on the black pavements to see. If it is too hot for you then it will definitely be too hot for your dogs paw pads. If your male dog does not want to sit down because it is to hot for their testicles then it is unsafe for the walk.
It can cause burns on their paw pads and then they will be limping around. Also, the dogs do not sweat out of their body, they regulate their body temperature from panting and you can cool them off by dipping their paws in cold water.
Walk them on the sidewalk or the grass or just wait until it gets cooler.
