I grew up with two dogs: a working dog and a "fun dog". The working dog was an aesthetic Australian shepherd/Blue heeler mix who was highly trained for herding cows. Our fun dog was Chewbaka, Chewie for short. He was a 100+ lb lab/German shepherd mix who loved to run, pull sleds, and wrestle. I currently am unable to have dogs myself, so I get my dog fix from taking my mother in law's Golden Doodle for runs around the lakes. I am available weekends and late afternoons on weekdays. I have a full time job besides dog sitting at a bank. I am pretty strong and don't mind being jumped on, so if you have a large dog that pulls his leash, no problem.
