i would never be able to have a house sitter, i recently went to my sisters graduation, and left early in the morning got in very late, knew that this would be the case so asked a friend (also my boss) to come and let the dogs out for me, i put the 2 nutters in to kennels, mainly because everytime jack sees her he wees up her legs

has done ever since he was a pup, so she just had the two labs to let out, she has Bruces sister and Bruce goes to work with me so he knows her well, but she still had a job getting in the house, if she didnt have experience of aggressive dogs she would have given up, and Bruce wouldnt hurt a fly hes all noise and size :D so i wouldnt even think of asking someone who doesnt know them to come in, but if you can find someone you trust and who the dogs get on with everything should be ok, ask to see references and go on recommendations if you can find someone who has used them before
