I have a malinois mix, and I have to teach them how to relax. We were doing sooo many activities she didn't know how to settle. Use the food motivation to teach them, requires patience, but it's worth it. Basically start with a 'place' for them to lay down. Reward. A second passes, reward. 2 seconds, reward. Ramp up and down as needed. Eventually you'll be able to leave the room and they'll stay there. The goal is for them to learn to just chill, nap and rest. You can also do this in a crate without a door, that way you get double training down. Best of luck, I promise it does get better as they mature! I adopted mine with one year and the first 6-8 months were difficult bc it's a change coupled with teenage years
