Start doing their training individually .....and take each dog out for walks and make them do their commands with distractions around. The dogs should be able to listen to all your commands, with other dogs, around and people around too.
You can teach the "stand" command...and do a "stand-stay" also.
Do a moving "down"...meaning they are coming towards you and they go into a "down".
Also healing...teach them a formal heal...so the dog has to stay right by your knee even if you turn, or slow down your pace.
If you dogs are well trained you can also get their CGC on them. Do a google search for what the test consists of and find out when the next tests will be done in your area. Nice to have some sort of training goals without getting bored.
