Firstly, we're pretty sure he has an owner, as he's been taken to the vet at least twice and yet has reappeared. Dogs don't usually escape from the pound.
Secondly, the dog isn't really interested in us. We love dogs, but this one just is not quite present. Always looking at the horizon and following his nose to the next adventure. We made a bet that day we'd see him again.
And here he is. I am going to have to buy more sausage for my pizza as he has scoffed the lot.
