Dog training...Taking food off plate, biting the wall, chewing on things, jumping, playing hard.?

running around the block is not enough. She's bored and that's probably why she's behaving bad. My 8 month old gets like that if i can't get him out on his runs. I take him for 2 runs a day for at least 30 min. It's not all running but walks too or i take him to my parents farm and let him run free and when he gets home he is wore out and goes to bed.
