We have a dog walker who comes and walks our dogs during lunchtime. We pay $15 a day for the walk. Lately we have been having issues though, she has locked the garage door three times and as a result I was locked out of the house with a 6 month old while I waited for DH to come home. (We don't lock garage door). She has left the front door unlocked twice and yesterday she forgot to close the garage door but reset the alarm. This meant the police came to our house. DH was furious. I'm willing to overlook everything and ask her to be more diligent, we talked to her about the previous incidents so she wouldn't be surprised if we didn't retain her services. DH wanted to fire her. What would you do?
