Jackson Heights Life

Hi,  I am looking for a responsible dog walker to help with my very old, sweet, big dog.  He is really gentle and responds well to the same.  He is a big dog with bad arthritis and requires very particular care.  I need someone who preferably lives in the neighborhood and can sometimes be available to help on short notice.  I need someone who can walk some evenings (10pm) and weekends.  I also need regular walks, usually 8-12 per week, during regular business hours, as he needs to be walked every four hours (and I work).  Looking for someone willing to offer a good rate due to high frequency of walks, but most important is someone who is really responsible/reliable, and willing and able to take really good care of my 15yr old, 65lb German Shepard mix. Reccomendations welcome, references and an in person meeting would be neccesary.  Thanks!
