My husband and I both work full time, but my older children are home off and on through the day. But when my daughter is at college or work and my son is at work - to be safe with 6 yorkies we have their pens they go in. They have water, food, pillow, and their blankets. They are not in there long. I get home around 3:45, so it works out great! They are probably only in there for 1 - 2 hours. I think this is the best - since I do not want them to get into anything and get hurt - so the pens is the best for them. I have seen one of my yorkies get on the coffee table - while I was home and was taking the magazines and ink pen from it and was starting to chew them up and this was with me home. So I can only imagine what they would do if I was not at home. I probably would not have a home to come home to and my yorkies would be sitting there with wood and fabric sticking out of their mouths with an expression such as, "I didn't do this!"
