what i was thinking of doing is making an appointment book, and only doing it while hubby is home. as he will be home for 6 months , then do the doggy walking only in the summer or warm weather once he goes back to work,so this way it works around my schedule . and i was thinking 10 for small dogs 15 for medium and 20 for big dogs. if i walk those sizes i havent fully decided if i just want to walk small dogs.
