      Best Mate grew up fast, no longer a cute and clumsy puppy, but a creature of astonishing beauty and grace and power, known and loved all over the park. Within the year they had found the small house they were looking for, with a walled garden at the back. It was nearer the park, but a little further away from school. That didn’t matter. Patrick’s dad dropped him off at the canal bridge as he always had done, and he’d walk along the tow-path past the sweet and sour smelling brown sauce factory and up the tow-path steps to the road, where Bossy Boots would be waiting with his lollipop stick.

      Ever since Mr Boots had told his fib about helping him out of the canal that day, Patrick had always done his best to avoid him. But he had to cross the road every day, and when he did Mr Boots was always waiting, ready with some feeble joke or other about what had happened. “No dogs in the canal today, Patrick?” or “No early morning swim. Patrick?” And every time he’d laugh like a drain as he ushered him across the road.

      In school they still talked about “The Great Puppy Rescue”. They’d all written stories about it and painted pictures too. These were still up on the wall in the front hall with all the sports cups and the school photographs, along with a cutting from the front page of the local newspaper, laminated and in big print so that everyone could easily read it. “Patrick’s Puppy Plunge” was the banner headline, and above it there was a photo of Patrick with Best Mate in his arms, with Mr Boots and Mrs Brightwell on either side of him, and a dozen other children around them, all grinning into the camera – except for Jimmy Rington, who wasn’t exactly glowering, but wasn’t smiling much either.

      So the hero-glow hung around Patrick all that year, which of course he quite liked. No one called him “loser” any more. No one laughed at him any more. So sometimes he even looked forward to school these days. The little greyhound had changed his whole life around, at school and at home. Best Mate was always there with his mum to meet him when he came out of school every afternoon. So everyone got to cuddle and pet him. Maybe this was why the legend of The Great Puppy Rescue was not forgotten – after all Best Mate was there to remind them of it every day. All the teachers seemed to love him too. Mrs Brightwell in particular made a great fuss of him and Patrick loved that – it made him feel very special.

      What he didn’t like so much was that Bossy Boots was now making out that he’d jumped into the canal himself to help rescue Best Mate. Worse still he was always trying to persuade Patrick’s mum to race him, that he was too good a greyhound to be kept at home just as a pet. He told everyone that Best Mate had champion written all over him. This of course only added to the sparkle of the legend, and it was a legend that was changing. The star of the legend had been Patrick at first, but it was Best Mate who was the star now. Patrick didn’t mind this in the least. On the contrary, as far as he was concerned Best Mate had always been the star. Every time Patrick came out of the school gates and saw him waiting there for him he felt so proud.

      Stories went around the school – spread mostly by Mr Boots – of how Best Mate had been seen running up on the park at full stretch, how no one had ever seen a dog run that fast. Everyone knew that Patrick and Best Mate had become completely inseparable, how Patrick never needed to put him on a lead any more, nor muzzle him; how he’d walk close beside Patrick down the street, his cheek touching Patrick’s leg. As faithful and fond as a guide dog, Best Mate was instantly protective, and even fearsome if he ever felt that anyone, dog or human, might be a threat to Patrick. The gentle eyes would flash, the hackles go up along his neck and back, and every muscle in his body would be suddenly tense and taut, ready to spring. But it took only a word or a glance from Patrick to calm him down at once. They spent so much time together that each seemed to understand the other instinctively by now, so much so that up in the park it was hardly ever necessary for Patrick to whistle for Best Mate, or call him back. He just came of his own accord.

      At home and at school everyone could see how happy Patrick had become since the day of The Great Puppy Rescue. “Less anxious, less isolated, more outgoing, more confident,” Mrs Brightwell had written in her school report. And it was true. Patrick laughed more these days, joined in more. Every story he wrote in his literacy class somehow managed to involve a dog, usually a greyhound. But Mr Butterworth didn’t mind. Patrick was writing pages and pages these days, instead of just a scrappy paragraph or two. In most of the pictures he painted, you could find a greyhound somewhere. And his bedroom wall was covered with pictures and photographs of Best Mate.

      Patrick spent every hour of his spare time and all his pocket money on him. He’d bring home chews or biscuits for him, whenever he went to the shops. He polished his name disc so that it gleamed, groomed him every evening, and even cleaned his teeth for him sometimes, so his breath wouldn’t smell. He’d make sure his food was just how Best Mate wanted it, but he would never stay to watch him eat it, because he knew Best Mate liked to do this in private. So he’d give him a pat and leave him to it. No one minded at all that Patrick had become one-track minded, because he was so obviously happy.

      Settled now in the new house, Best Mate had long since outgrown his basket – they had completely miscalculated how big and tall he was going to grow. But they didn’t need to get another one, because he now occupied the sofa. A “giraffe-dog” Patrick’s dad called him. His mum didn’t mind too much because he was a clean-living dog. He left no hairs behind him, and brought very little dirt in from the garden or back from the park. He did bury his bones sometimes under the cushions on the sofa, but Patrick usually found those and got rid of them before his mum discovered them.

      Best Mate would lie there quite happily on the sofa for most of the day waiting to fetch Patrick home from school, longing for his daily run in the park. They’d walk together up to their favourite bench, right at the top of the park. From there Patrick could watch Best Mate run, whichever way he went. Once into his stride this “giraffe-dog” would be transformed into a “cheetah-dog,” and people would simply stand and stare as he streaked away into the distance. From time to time other dogs would try to chase him, try to keep up, but none of them had the speed nor the stamina to stay with him for long. He could outrun and outsmart all of them. He could jink like a gazelle, bound like a springbok. And Patrick was always waiting for him by the bench when he came back.

      Every time Patrick watched him run he could feel his whole body warming to the roots of his hair with the sheer thrill of it. And whenever Best Mate came haring back to him over the park, Patrick was filled with a surge of such pride and joy
