sorry to hear that rosie has been atacked i do hope she's ok , my sonnie was attacked by another dog about 4 years ago this dog ran out of it's own house and just grabed him as he was on the lead he couldn't defend himself very well and ended up at the vet's i was quite lucky the owner of that dog paid all the vet's bills so you def want to try and find out who it is you may be able to claim back from them.sending you and rosie my best wishes
