Just literally had the joy of meeting an owner-free unmuzzled xl type dog when I was out with my pooch.
Rather unnerving as I was in the middle of nowhere and no obvious out for me or my dog.
Slowly retreated up a dirt track but the dog started following at pace.
Fortunately a car had seen what was happening and the driver came up the track and got between us and the dog and reversed forcing it away from us. He said it had been roaming around for a while and the polis were on their way. Safely home and feeling relieved.
This following last night's walk where we walked past a house with a guy blethering to someone else at their doorway and a doberman comes belting out past them and has a couple of goes at my pooch. Give her her due, squared up to it and growled and barked back before the owner managed to get it in the house again. My pooch would be a snack to either of these dogs.
