German shepherd age 2

We have to rehome our beautiful german shepherd. Our living space has decreased and our family is increasing. Tank needs someone who has the time to run him and the land for him to run in. Also someone who has the knowledge or money to put him through some good training. He is house and crate trained. He is great with other animals once he knows them. He is great with children. He truly is a good boy. He just needs love an attention and he doesn't get much attention or the exercise he needs. He is 2 will be 3 in may. Approx 65 lbs. Black and tan in color.
