Hi! I have a 7 month old chocolate lab named Lily. My husband owns his own business and has a large area where he meets his crew every morning. He takes Lily with him each morning and will play fetch with her, but lately she's gotten very demanding and barks so much (to have the ball thrown) that he can't even talk to his crew. What can we do to address this issue? Also, she's becoming very vocal over noises in and outside of the house, knocks at the door, strangers she sees on walks, etc - it's becoming a big issue for us. Thanks!
