If it's that hot, he really shouldn't be walking in it. Remember, he's wearing a fur coat. You don't want him to get heat stroke, I had a dog get this, a stray, I almost lost him. He's trying to tell you it's too much for him, please listen to him. And remember, what ever he's walking on is extremely hot on his feet. Would you walk barefoot where you are taking him? Unless its lush grass, it may be burning his feet.
