So my wife has recently been doing a babysitter share with another couple we met. The wife will come to our house while we go out and my wife goes there when they go out. We've done this probably three times and our daughter has been around their dog at least four times. On Saturday night my wife was babysitting and brought our daughter with her to watch their kid. Our daughter is two and five months. Near the end of the night everything was calm and about ready for bed. Out of nowhere the dog came up and bit our daughter in the face. There was no provoking, or anything to suggest this would happen. She was eating some popcorn, maybe he wanted it real bad. But they had been there hours before this happened. We went to the emergency room and the dad came with us and stayed the whole time, which was nice. She ended up getting four stitches and lots of holes on her face. She was a trooper and handled it like a champ. We told the couple we wouldn't press charges on the dog. It's been two days now. The couple already filled a claim with their home owners insurance and are paying any bills. We're just wondering if there is some legal action we should be taking regardless of how nice we want to be or the fact it was a crazy accident. Any advice?
