Thanks for the replies. My neighbour is retired so is at home for the best part of the day. He takes the car, with dog, out for a couple of hours a day. I don't know if the dog is exercised while he's out but it's left in the car when he gets back. For example, I got home today at midday, it was in the car then, it was still there at 3:30pm when I went out. I got home at 5pm and the car was gone, he got back around 6pm, left the dog in the car and it is still there now at 7:20pm. It will probably be there now till around 10pm when he takes it indoors. Can't say whether there is any water in there with it as the crate has boards around it to about two-thirds the height of the crate. All that's visible of the dog is it's head and the tip of it's tail. That's just today, most days seem to be the same routine.
