The way in which Maggie would signify, every morning, that she was deliriously pleased to see me was to bite Trudie on the neck. This was also her way of signifying that she was deliriously excited at the prospect of going for a walk, it was her way of signifying that she was having a walk and really enjoying it, it was her way of signifying she wanted to be let into the house, it was her way of signifying she wanted to be let out of the house. Continuously and playfully biting Trudie on the neck was, in short, her way of life.

Maggie was a handsome dog. She was not a poodle, and in fact the sort of breed of dog she was was continuously on the tip of my tongue. I’m not very good with dog breeds, but Maggie was one of the real classic, obvious ones: a sleek, black and tan, vaguely retrieverish sort of big beagle sort of thing. What are they called. Labradors? Spaniels? Elkhounds? Samoyeds? I asked my friend Michael, the film producer, once I felt I knew him well enough to admit that I couldn’t quite put my finger on the sort of breed of dog Maggie was, despite the fact that it was so obvious.

“Maggie,” he said, in his slow, serious Texan drawl, “is a mutt.”

So every morning the three of us would set out: me, the large English writer, Trudie the poodle, and Maggie the mutt. I would run-jog-stroll along the wide dirt track that ran through the dry red dunes, Trudie would gambol friskily along, this way and that, ears flapping, and Maggie would bowl along cheerily biting her neck. Trudie was extraordinarily good-natured and long-suffering about this, but every now and then she would suddenly get monumentally fed up. At that moment she would execute a sudden midair about-turn, land squarely on her feet facing Maggie, and give her an extremely pointed look, whereupon Maggie would suddenly sit and start gently gnawing her own rear right foot as if she were bored with Trudie anyway.

Then they’d start up again and go running and rolling and tumbling, chasing and biting, out through the dunes, through the scrubby grass and undergrowth, and then every now and then would suddenly and inexplicably come to a halt as if they had both, simultaneously, run out of moves. They would then stare into the middle distance in embarrassment for a bit before starting up again.
