Need to find a new home ASAP

I recently got a German Shepherd mix. I was told that she was about 6 months old; April would be birth month. She is also medium size as of right now. I would guess around 25-30lbs. Since getting her, I have had some health issues arise as well as not being able to give her the proper attention she deserves. She has been wonderful with my children, I have trained her to wait for her food until I allow her to "go" and is everything that I have wanted in a pup. However, I find it unfair to her that I do not have a yard for her to roam around in. Nor the time she needs to spend outdoors. She would come with food, crate, toys, leash and treats.
