Auggie will be 6 in November and is still crated, except he is free in my room at night. He MIGHT be okay to be left out these days... he hasn't destroyed anything in a good while... (watch, he will now proceed to destroy something just to prove me wrong.)
If Payton turns out he's staying intact, and Pepper is staying intact, so if I have all three dogs, poor Pepper will at least always need to be crated because Auggie is annoying and I don't need any oopses with a silent heat or anything... assuming the boys end up completely fine to be left alone together, I guess I could crate the girl and leave the boys out.
But honestly it just seems easier to crate them all and not have to worry about any of it. All they would do is sleep anyway, and Auggie goes in his crate to sleep even when I'm home...
