My little girl came home from the in-laws yesterday, I noticed a mark on her arm but left it until this morning to text. I sent a picture and said 'I don't know what this is on names arm' mil then phoned me and said she was really sorry, but her dog had bitten dd, she said dd threw a bike at her (dd is 2, we have our own dog at home and she's never done anything like that) so the dog bit her. I was a bit shocked really that mil didn't tell me without me asking first. My other half is (rightfully) livid, we don't want to seem harsh but dd won't be going over again, even with the dog locked away I still wouldn't feel comfortable.
