Hello Everybody.  Our sons new dog Balla, a beautiful 4 year old Akita, will be staying with us during the day while our son is at work.  We know that he loves to spend part of the day outside and so we would like to provide him with a safe area to relax in.  We have a large raised shed he can sit in but the fence around the lawn area we feel may be too low.  We have no idea how high Balla can jump so can anyone come up with any suggestion of an ideal fence height?  We live on a farm, surrounded by fields of sheep (Balla is fascinated!) and we would like to keep him and them safe! Help! Luv from Kaz & Balla in Scotland (and from Bruno, the Pointer)
