They are bored to destruction... literally ! You have to walk them... at least 1 hour hard exercise... preferably 2 hours a day. They are not "entertain themselves" dogs. No dog is. You need to work with them.. re train them ,school them. Agility is a great idea. many parts of the sets you can make yourself. EBay is also a good source.

Get training books from the Library... KNOW what they need !

But bottom line is.. these are your dogs and you are going to need to work with them and provide them with stimulous and exercise.

Again.... Good Luck.. but you are going to need to change your life with them to have happy calm dogs. You CAN do this.
