We've had some bad experiences with dog walkers in Pittsburgh. We have been very happy with Jen and Mathew, they're reliable and very professional. They clearly love dogs and treat our boy well while respecting our training wishes. They keep a journal for our dog at our house so we know what happened on the daily stroll (since his bowel movements are of utmost importance). We have a busy schedule that frequently changes, they are very accommodating and can come for breakfast, lunch or dinner. The pushover for us was they care for him when we go out of town, he had the best time staying with them.
