Pet Care Needed

I have a very lovable friendly but highly energetic German Shorthaired Pointer. She is 1 years old and I have to work from 7:00 in the morning until 5:30 in the afternoon and she has to be crated. I have a fenced-in yard where you can safely play ball with her she loves to play fetch with her Ball but I prefer that she goes on nice Long Leash walk which she enjoys too. that seems to get most of her energy out. A little bit of both would be Optimal. I work everyday and sometimes my husband works from home so on those days you would not need to come, but this is a week to week notice.
