Shilah - 2 year old GSD, highly strung and high energy, always on the go, he almost never sleeps or even lays down during the day.

Kofi- 12 month old working line GSD, high drive and high energy but in a much more clear headed way than Shilah and has a good off switch.

Flatcoats are high energy outdoors - but act like couch potatoes indoors and always find the comfiest place to relax.
