About three months later the pup was as big as an ordinary full-grown dog, and his coat looked like a compromise between a calfskin and one of these hairbrush door mats you use to wipe your feet on in muddy weather. He did not look like the same pup. He was long limbed and awkward and useless, and homely as a shopworn fifty-cent yellow plush manicure set. Murchison began to feel that he didn't really need a dog, but Brownlee was as enthusiastic as ever. He would go over to Murchison's fairly oozing dog knowledge. “I'll tell you what that dog is,” he would say. “That dog is a cross between a Great Dane and an English Deerhound. You've got a very valuable dog there, Murchison, a very valuable dog. He comes of fine stock on both sides, and it is a cross you don't often see. I never saw it, and I've seen all kinds of crossed dogs.” Then Massett would drop in and walk around the dog admiringly for a few minutes and absorb his beauties. “Murchison,” he would say, “do you know what that dog is? That dog is a pure cross between a Siberian wolfhound and a Newfoundland. You treat that dog right and you'll have a fortune in him. Why, a pure Siberian wolfhound is worth a thousand dollars, and a good--a really good Newfoundland, mind you--is worth two thousand, and you've got both in one dog. That's three thousand dollars' worth of dog!” In the next six months Fluff grew. He broadened out and lengthened and heightened, and every day or two Brownlee or Massett would discover a new strain of dog in him. They pointed out to Murchison all the marks by which he could tell the different kinds of dog that were combined in Fluff, and every time they discovered a new one they held a sort of jubilee, and bragged and swelled their chests. They seemed to spend all their time thinking up odd and strange kinds of dog that Fluff had in him. Brownlee discovered the traces of Cuban bloodhound, Kamtchatka hound, beagle, Brague de Bengale, and Thibet mastiff, but Massett first traced the stag-hound, Turkoman watchdog, Dachshund, and Harrier in him. [Illustration: 26] Murchison, not being a doggish man, never claimed to have noticed any of these family resemblances, and never said what he thought the dog really was until a month or two later, when he gave it as his opinion that the dog was a cross between a wolf, a Shetland pony, and hyena. It was about that time that Fluff had to be chained. He had begun to eat other dogs, and children and chickens. The first night Murchison chained him to his kennel Fluff walked half a mile, taking the kennel along, and then only stopped because the kennel got tangled with a lamp-post. The man who brought him home claimed that Fluff was nearly asphyxiated when he found him; said he gnawed half through the lamp-post, and that gas got in his lungs, but this was not true. Murchison learned afterwards that it was only a gasoline lamp-post, and a wooden one.
