If I am picked to house sit your house I will promise to Treat the house with the utmost respect. Return it to the home-owners in as good as, or better, shape then you arrived in Stick to the home-owners’ guidelines on correspondence, how to deal with mail, instructions for pets, etc Be prepared to deal with adverse situations like chasing dogs through muddy fields and disposing of a dead chicken. Bad things can (and probably will) go wrong at some point. Be sure to have emergency contact info on hand, and be honest with the home-owners about anything that comes up.
I have house sat over homes and they are all happy to be references. I am a true animal lover. Dog are my absolute favorite thing in the world. I have grown up and have always dog sat since leaving for university.
