Biết khi nào trời quá nóng không thích hợp để dắt chó đi dạo. Đem theo nhiều nước và thức ăn. Nghỉ ngơi khi cần thiết và vào nơi râm mát khi có thể.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
The temperature will often determine the best time to take your dog walking. Earlier in the day or later in the evening are suitable times of day to walk your dog. Avoid high noon as the pavement may be too hot for your dog’s feet. The best way to test if it is too hot is to place your bare hand on the pavement. If after only five seconds you have to remove your hand then chances are it is too hot. Along with poop bags and your clicker, carry a portable bowl and a bottle of water for your pet. K
