Suggestions for crate-training an old dog?

I have 2 dogs - I have 2 med. sized crates - sometimes they share and sleep together in their crates and sometimes they don't. I got them each their own crates, but large enough that they could sleep together if they wanted to. As far as getting them in the crate and have them start using it - my suggestion would be to start feeding them in their separate crates - put the bowl of food in the crate. Also, put a blanket or bed in the crate (maybe the one they use to sleep on now) and some toys if they like that kind of stuff. But feeding them in the crate is usually the best way to get them in the habit of using the crates - it will take a week or two before they are using them on their own, maybe sooner. Good Luck!
