<human>: Can you summarize the given text in a few sentences?

My parents recently moved to a semi-rural area, which allows them quite a bit of space. They have a large lot behind their house, however between the house and this lot is a circular driveway, car port and shed. They also have a large front lawn, which they have considered fencing in to allow their year old Boxer-Hound mix some room to run. However, it runs straight up against a road which has  a fairly fast speed limit that is often ignored. 

Due to this location, lack of side walks, and the health status of my folks, taking this energetic young pup on long walks is unlikely. I have been trying to devise some manner for them to fence in or contain their pup in their back lot, so she can get the exercise she deserves. However, the resources to this with are quite limited. As my step-father and myself are both fairly handy, I figured a DIY project would be feasible, but the main question is what sorts of material would be the best choice. 

Their pup is about 50 pounds and loves to jump, so the classic chicken wire may be to flimsy. Also, backing up to their lot is the lot of some neighbors who have dogs trained to be vicious and have proven that they can jump their own fence. So, I'd like to devise a way to protect their dog, allow her to have a happier life and do it in an affordable manner.
<bot>: The yard has a weird set up, must allow a large puppy to exercise while still protecting her from neighboring dogs and speeding cars.
