Is there any way you could put him at the shelter and ask them to contact you if they're going to put him to sleep? Then you could go and get him before they do? I don't know how the shelters work over there, but, if they would notify you the day before or something.....He's very attractive, and, young, though, so, it seems like he'd stand a good chance of getting adopted. But, if he's a native dog, with food and water and shelter, I think he'd be alright outside. Is there a fenced in yard or does he need to be tied up all the time? Sorry, I didn't read every post. Maybe even just foster him until you could find a place for him. And, as far as it being hot, and, him having fur...fur acts as an insulator, keeping him warm in winter and cool in summer. He doesn't look like he has a double coat like a husky or a newfoundland, he'd probably be alright if he was provided adequate shelter and water. Keep us posted, though.
