Leopoldo - you have to adjust as much as the dog. By that I mean, you have to get up and take your dog out early (5am) during the hottest months - to take advantage of the lowest daytime temps. They'll still be in the 30s but the sun is low and the ground is much cooler on the dog's feet.

My dog has a double coat (being bred for a much colder climate) - she slows down in summer, I take a half frozen 1.5 litre bottle of water with us and a dish. She always has access to cold water when we are out in hot temperatures. I also make sure she doesn't get "too" active because then she over heats and it becomes difficult to cool her down - most housing here has their water tanks on the roof - even in summer at night the water is often in the middle to high 30C range - you can't cool a dog down with tap water as a result - you have to make sure it doesn't get overheated in the first place.

You will find that in summer you turn off your water heaters and use that water as "cool" water because the water heaters are inside and subject to AC and the cold water tap becomes your hot water. It's confusing at first but you do get used to it.
