Jake is a 4 yr old Great Dane/Black Lab who is a service dog for an elderly man with serious back injuries.  In the house he is a wonderful service pal but as a young lab he needs to be able to run off his puppy energy.  He is currently chained to a tree in the front yard and it is very hard for his owner to walk down the stairs to get out to the tree. His owner needs to be able to take care of Jake while not injuring himself.
