I was on the other side of the fence, my child got hurt at someone else's house. The kids were playing in the backyard and we could see them out the window and suddenly the dog was dragging my 3 year old by his coat sleeve. We all ran out there and besides being scared out of his mind, my son was ok. The rest of the visit there was very awkward and our hosts even made a joke about calling a lawyer. We told them we wouldn't do that, but we never heard from those people again. We called them several times to have them over for dinner and they never called back.
A phone call to see how my son was doing or even if his coat was damaged would have been nice. He was wearing a new Gap down-filled coat when it happened and the dog tore holes in it, so I had to get him a new coat.
Keep in touch to see how he's doing and find out about your homeowners.
