Sara renamed Pollux to Pongo and this time the name seems to be sticking (although she went though many names for him).
Sara also normally takes "the chacks" to a class in the evening for a few hours, most of the time where they can run around a lot but never seem to get tired (can we hook them up to our power grid??). We do what we can to tire them out but it never seems to work. :S
I also think she's just being an annoying adolescent.
As for crate training - Luna is extremely good with it. We tell her crate and she goes in (most of the time), she just doesn't like to be in there long (feeding time is OK, etc).
Pongo is harder but all it takes is a cookie tossed towards the back of it and he dives in (We still do that with Luna sometimes, too, so there are rewards in there sometimes).
