NEW YORK - Bodies tensed and noses twitching, the dogs sniff the hunting ground before them: a lower Manhattan alley, grimy, dim and perfect for rats. With a terse command - "Now!" - the chase is on.
Circling, bounding over and pawing at a mound of garbage bags, the four dogs quickly have rodents on the run.
"Come on ... I mean, 'tally ho!' " says one of their owners, Susan Friedenberg.
In a whirl of barks, pants and wagging tails, dogs tunnel among the bags and bolt down the alley as their quarry tries to scurry away.
Within five minutes, the city has two fewer rats.
In a scrappy, street-wise cousin of mannerly countryside fox hunts, on terrain far from the European farms and fields where many of the dogs' ancestors were bred to scramble after vermin and foxes, their masters sport trash-poking sticks instead of riding crops and say it's just as viable an exercise for the animals' centuries-old skills.
"It's about maintaining the breed type through actual work," said Richard Reynolds, a New Jersey-based business analyst and longtime dog breeder who might be considered the group's organizer - if it would accept being called organized.
Known with a chuckle as the Ryders Alley Trencher-fed Society - parse the acronym - the rodent-hunters have been scouring downtown byways for more than a decade, meeting weekly when weather allows.
On a couple of recent nights, an eclectic group of ratters converged on an alley near City Hall about an hour after sunset. The lineups included two border terriers; a wire-haired dachshund; a Jack Russell terrier/Australian cattle dog mix; a Patterdale terrier, an intense, no-nonsense breed that's uncommon in this country; and a feist, a type of dog developed in the American South to tree squirrels.
"Get 'im! Go!" Serge Lozach yelled as his cairn terrier, Hudson, streaked down an alley after a fleeing rat. Unlike many of the other owners, Lozach doesn't breed or show dogs, but he has taken Hudson to several alley hunts.
"I like watching him have fun," Lozach said.
Although the dogs have hunting instincts, it takes training to capitalize on them. Just because your pet runs after backyard squirrels doesn't mean it could ever catch one.
The night's kill ends up in a trash bin.
While dog owners may see it as time-honored pursuit, rat-hunting riles animal-rights advocates. People for the Ethical Treatment of Animals, which opposes hunting in general, expressed outrage after video of a dog snatching rats in a New York City park surfaced online two years ago.
PETA spokesman Martin Mersereau calls the alley rat quests "a twisted blood sport masquerading as rodent control."
Reynolds counters that "there are lots of worse things that people do to rats," noting that poisons can sicken the animals for hours.
In one recent foray, the dogs dispatched 13 rats within about a half-hour.
The dogs prowled and prodded for about 90 more minutes before the group gave up for the night. But not to worry, said dachshund owner Trudy Kawami.
"There will always be a million rats in the naked city."
"A twisted blood sport masquerading as rodent control."
