honestly, he wants to be with his family…unless you have some pressing NEED for him to be outside, let him stay in. in fact, i’d crate him away from windows and give him some sort of radio in the room so he doesn’t hear the birds.
as for the rest of his carrying on…he sounds BORED. what do you do with him when you’re home? are you actively training him? if not, you need to start.
dogs don’t need vegetables in their diet.
