Well if my Lilly says it's ok to have a walking machine then I will get one myself.

I will construct a rotary one like Jaime's today and having it working by this afternoon. I will make it 20mtr dia so the dogs can run if they like. I could possibly use the round yard that I use for the orses to set it up in. It's 20 mtrs in Dia. Will deciede in 30 minutes what to do.
I think my Lilly will be proud of me.
