OMG Eileen must seen this today , hope little Molly is ok. You must have got the fright of your life!!!! Things just happen so fast, you can't blame yourself you did not know the dog was there.
This is how my little Lottie is a nightmare out a barks at everything she has been run at by dogs 3 times and the first was when she was very young,I manged to get her up but it left her very shaken! Hopefully Molly won't be affected long term by this. She may have some bruising that you can't see due to her hair but I know you will keep your eye on her and sounds as if her wee sister is also looking out for her.
Sending you all a big hug
