The neighbour's dog has been visiting us for a month or so, bringing himself over, climbing through our fence, and slipping in through the back door up to three times in a day. He's only a month younger than our dog but a total layabout who just wants pampering, whereas our dog wants energetic play, so they don't fully get along but increasingly tolerate each other and seem to want each other's company.
Our dog communicates vocally when he's got something to express, whereas the neighbour's dog was always silent until just a couple of days ago, when he started talking to us. Last night he mouthed my wrist with a big smile and puppy-eye roll. Labrador ancestry at play, perhaps?
