make sure that...
the fence has no holes and is sturdy,
the electrical outlets are covered with plastic baby thingies,
there are no wires, cords exposed,
all small items (anything she can chew) is up and off the ground,
all other animals are friendly or are secured (like a caged animal),
no food near the ground she could get to,
yard is clear of sharp objects or anything that could hurt her to eat,
she has a place to eat and to sleep.
that's all i can think of for right now. you also might want to keep the deed to the house handy so that they know you own it (because if you rent they will have to ask the owner if you can have a dog).
omg omg omg - good luck!!!!!!!!!!!!!!! keep workin on Guy!!!!!
