Pet Walker - Now Hiring

I have a 1. 5-year-old blue heeler who is very sweet and very smart but skittish around other dogs. (He even barks at dogs on TV, and similarly does not like cats and horses on the screen) He is very high energy, so I walk him and throw the ball outside at least an hour each day. We have a fenced backyard. He has had training, although sometimes I think he is training me! I am working during the day and so someone to walk him twice a week in early afternoon would be ideal. I am also looking for a housesitter when I travel, which is about 5 days a month. If that same person could housesit and take care of my pup, even better.
