Johnnette Rule knows all too well how her job can become a real dogfight - like the day the 10-year veteran mail carrier had to use her satchel to fend off a stray German shepherd.

Whether born on the streets or turned away from homes, wild dogs or their predecessors once were pets. But when they run and breed in groups, they cause a lot of grief."We've had carriers who have had plugs torn out of their arms and legs, many who have had their clothes torn by dogs," Rule said. "It's really ugly."

And it's not just in Detroit.

In March, an Illinois farmer received $1,300 from the state, compensation for 26 pigs killed in 1993 by a pack of wild dogs. Dogs killed two ostriches in Oregon, fatally attacked a $15,000 horse in Tennessee and joined coyotes in killing livestock and pets in Colorado.

In the past year, a small pack of stray dogs attacked and injured a Massachusetts boy on his way to a school bus stop. In Oklahoma City, front-porch mail delivery in some neighborhoods was halted after dogs attacked several carriers.

Postal Service spokesman Mark Saunders says dogs attack 2,700 letter carriers across the country each year, costing taxpayers about $25 million for medical expenses and substitute carriers. He didn't know how many of those attacks were by wild dogs.

In Detroit, the dog menace is considered so bad that the city's postmaster threatened to stop delivering mail to some areas.

"A lot of people are saying that because of the dogs, they're sometimes trapped in their homes," said Donyale Stephen, an assistant city om-buds-man.

Of the top 10 complaints to the office, roaming dogs were third this year. Dogs had never before been on the 24-year-old list.

The city's Animal Control Division recently got four new vehicles to boost its dog-catching ability.

"We've been trying to get as many dogs off the street as we can," Donald Hamel, the animal control office's supervisor, said Thursday.

He said his division has made arrangements for two more animal control officers, though they weren't included in the budget, to bring the total to 15. They are responsible for 144 square miles in the city of 1 million people.
