New dog toy

Out younger chihuahua, Lil' Bit, loves the bad cuz toys. She got her first one about five years ago and as of today is on her fourth. She plays with them until they no longer squeak and have all kinds of "war" wounds. Even then she will still carry it with her everywhere, literally. She takes it to bed, to go potty, anywhere we may go be it a trip out of state or just down the road. She has to have it with her at all times, so no matter how much I try to keep them clean they always end up smelly. It's like her safety blanket. So today I finally got her another new one, one that squeaks and is, of course, squeaky clean. What does this mean for us? Well, it means that not only will she NOT play with the new one, she's going to search for her old one for weeks and weeks before finally giving in. lol.

Looking for input!!

What are your thoughts on having large dogs inside? What about when you and your spouse are gone 8+ hrs. each day and the large dog is stuck inside and rarely gets to go out during the daytime unless it's on a weekend? How would you like to have that kind of life, only seeing the sunshine through a window for about five days a week. What if this large dog was/is high energy and needs more attention? What would you do?
