Yorkies are great, I love my little guy. I am not working this summer so am home with him or I can take him wherever with me, but come September, I will be back at work and Chewy will be at home in his pen with animal planet on!!!
Many people here leave their yorkies at home during the day and they do fine. As long as they have some food and water and the TV or radio on, I think you will be OK. Just shower the pup with attention when you get home
