The title says it all really. The ex has a dog. I quite like him but he is pretty willful (dog not the ex). The dog bit his lady friend - stitches, the lot. So the ex has ditched the dog. But now I find out that the dog has been growling and snapping at my kids for months and that he bit a friend who came to play too. So dog bites a kid and ex does nothing. Dog bites former friend who was sleeping with my husband and ex takes action. Wtf???!
