Walking in heat, Bang Na

I am take Pepsi out in the morning at 6 am every day, but last week the heat is too much and he come back with his tongue all the way out. Bang Na is hot in May, but this is worse. Even the asphalt is steaming. So now I am change the time. Early early in the morning before sunrise, then again after 7 pm when the road is cool. Pepsi is Thai Bangkaew dog, very strong, but he is still a dog and he cannot sweat like human. I bought a cooling mat from the Lazada and put a water bottle in the bag. My wife says I am crazy to carry water for the dog but I think is good idea. Also I learn to watch his paws. If they are very hot or he is licking them a lot, we go home immediately. In my country we walk in summer because it is nice. Here is opposite. Thailand is beautiful but the heat is serious business.
