Took the dogs out for a quick pee break, and somewhere in the bushes I could hear a large shuffling grunting thing. Hounds shot after it and then Mollydog SCREAMED and they both came hurtling back to me. (Bob simply stood there throughout and looked confused).
I'm guessing badger, on the grounds that I'm pretty sure there are no pigs in my garden. It sounded like a pig. An angry pig. A HUGE angry pig!
Looks like whatever it did to Mollydog she ran away fast enough not to get visibly hurt. Phew.
