Let My Dogs Run

Hi everyone. So here is the situation. We have 3 rescue dogs, they are part of our family, Ranger, Quincy and George.  They have always had a huge fenced in area to run. Long story short, we had to move. At this house they are going to be chained to the deck... a very long chain but still chained. I hate this but there is no fence at the new house and it would kill me if they ran off, which I know they will. I put harness on them attached to the ropes, they will have alot of room to move but heres the other problem. My 4 year old daughter just loves running with her doggies. She won't be able to now because I am not risking her running around with 3 dogs on ropes. Too dangerous and not worth the risk. We priced a gignatic dog run, it was just over a thousand dollars. This thing is amazing. We can't afford it but I must find a way. My husband works hard driving transport truck but with bills and everything we just cannot make it work right now. My one little dog is a pointer, she was rescued from a heavy chain and it just kills me thinking of tying her back up. She has learned to run and jump and have so much fun. The other 2 are the same, I think they would go crazy losing some freedom. So if you can help us out that would be awesome. Hoping to get this run before winter at the latest but my goal is summer. I will send videos to people who request one of them running. Kind of like a before and after video. I don't know if this will work but it sure is worth a shot.
