Hi and welcome to YT. I know I work long days as well. I or my boyfriend go home and visit at lunch time and try and tag team so he is not left alone every day. Do you go to the gym every day after work? Perhaps you could do exercises outdoors and bring your Yorkie with you. You can do free weights at home and go for walks instead of the treadmill. Could you hire a pet walker to come in and visit for a hour a day say at lunch time. You Yorkie is showing you how lonely and bored they are by acting out. Is there a doggie day care for small dogs near you. New toys with no one to play with is not much fun. I feel for you but you need to modify your schedule to find more time. I apologize if I sound mean but only you can fix this by finding more time or a companion to visit.
