at his age - he isn't going to need much yard - a nice walk or a romp in a fenced in area once in awhile should suffice. I'm not sure if you will try to house break him to bring him inside but if you do good luck with it!
Once he learns what a tennis ball is it should be fun!
Keegan has hip dysplasia in both hips worse on the right and has torn both ACL's that we healed up holistically so she doesn't get much running time as much as she loves it - she just doesn't know she needs to sloooww down. She chases the ball full bore and then slams to a stop. She did that once with my parents at their cottage and she slammed into a tree! They had to drive all over creation to find a vet b/c she wouldn't put any weight on one of her front legs and when they did there was a cat in the waiting room and she PULLED my dad to the front of the waiting room -which never happens!

keep us updated!
