I read it as the daughter came to help for two weeks, and at the end of the two weeks the son-in-law came to pick her up, was bitten by the dog, the dog bite was reported (probably because son-in-law sensibly had it looked at in case he needed stitches or a shot or something), and once they were back home and the dust had settled, the daughter told her parents that the bite had been reported.
