Yeah, our oldest is 11, so I could just put on some music, lay down some pee pads and she'll lay on her futon all day. Even she and the girl puppy usually do well together alone. We had to leave them alone for some longer times when we moved, and they didn't cause problems.
But then there's the little guy who is a year and a half. When it's him and the puppy they can get into mischief. You never know. The majority of the time they are just fine, but then suddenly they can tear apart a doormat like they did a few weeks ago.
It would be awful to have to crate them, but they'd be alone for a long time every day. I feel like I didn't rescue them off the street to have to do that.
