Liz has been giving our 2 big mutts (45 & 55 lbs) a midday walk every weekday for over 6 months and we have been very happy with her. She is flexible with our schedule when we have unexpected days off and don't need walks, and has always notified us well in advance of holidays when she will be unavailable. Sadly, we are moving too far away for Liz to continue her visits. She has our pups well trained and has set the bar high for finding a replacement after we move!
