I cleaned a house 3 months ago, with a dog inside that i had stroked before, ( a border collie) but this day owners were out, so when i finished i put a call back card in and the thing bloody bit me, right into my finger, ripping my finger nail off
very painful , 3 hours up the hospital, £18 in presrciptions and i couldn't do any ten pin bowling for three weeks >: thankfully and most importantly though i could still work, she said the dog dosn't like hands coming through the letter box and that she's normally shut in the living room, the daughter for got to close the door, mmmm i said you should have a box on your wall for mail, if that had been a childs finger they would have lost it, ..... they still not put box up. and yes i still clean their windows, but i've learnt a lesson, and a painful one, never trust a dog, specially when putting call back cards in.
here's a pic if you want to see it ....
