I'm looking for a great walker for our ~55 lb dog Luna, a lab / pit rescue. She's a little over 2 years old, and we've had for 1. 5 years now. Luna is super sweet, and usually way more interested in her toys than other dogs, but she does like playing with other dogs (as long as there's no ball to distract her). She is mostly well behaved (with the exception of sometimes jumping up to greet guests). My wife has been taking care during weekdays, but she's going back to work (Tues-Fri only), and we need someone to take Luna out for exercise and a midday potty break.
