That's a great suggestion, Karen.
Good luck - it does sound like you have some challenges, but don't give up yet, there's a few things you can try.
Take them out for good-length walks a couple times every day. It'll help expend some of that pent-up energy. Do you have a dogpark nearby? That might give them a chance to stretch those legs. As for slipping her collar, can you switch her to a halter for walks? They are not as easy to slip thru.
Inside, you might want to consider using a crate or, better yet, a specific dog-proofed room inside to keep them in when you need to leave. Create some interesting things for them to do- bored dogs get destructive.
As the saying goes, "A tired dog is a good dog".
