Despite Mack's weary legs and the rainy weather, humane society officials said the day was a success.
Mary Porterfield, adoption counselor for the society's shelter at 8513 Lyons Road, said the walk brought in about $2,000.
In a good year with good weather, the walk usually can net the shelter about $4,000, said Marsha Stoops, assistant director.
The society runs its shelter on donations, fund-raisers and adoption fees, Stoops said. The biggest moneymaker, its annual auction, brought in $5,000 this year, society officials said.
"We're always fund raising," Porterfield said. "Income never meets expenses, but we're holding our own."
In Sunday's event, dog owners solicited pledges from sponsors. Owners who brought in more than $25 received T-shirts.
The event is held to symbolize support for the shelter and concern for homeless animals, Porterfield said.
The society's mailing list exceeds 3,000 people, she said when asked about membership.
The shelter, which opened 28 years ago, operates with three full-time employees and three part-timers, plus a dozen volunteers.
Its current animal population is 60 cats and 37 dogs, Porterfield said.
Last year, 400 dogs were dropped off at the shelter. Of them, 200 were adopted and 86 were reclaimed by their owners.
"Cats are a different story," Stoops said. Last year, the shelter took in 969 cats, with only 164 adopted and 12 reclaimed by owners.
"We get a lot of feral cats and sick kittens," she said.
Animals that are not adopted are euthanized, shelter officials said.
Kirk and Melissa Palermo-Spero of Greencastle, Pa., led Lucy, their 6-month-old black mixed breed, on the walk. Lucy was adopted in May.
"It's working out wonderfully," Melissa said. "We love her. We've also adopted four cats. Lucy gets along with them pretty well. We highly recommend adoption."
Greg and Kate Wenzloff of Waynesboro went on the walk with their two dogs - Seven, 5, and Rugby, 4. They adopted Seven four years ago and got Rugby from the shelter as a pup.
Before Seven and Rugby, the Wenzloffs adopted Sally, a beagle who died a few weeks ago at age 16, and Kip, who died four years ago at age 7.
Frazier, a 7-year-old, slightly paunchy golden retriever, did admirable work on Sunday's walk. He brought in $110 in pledges, said his owner, Robin Flegel.
Flegel said she doesn't understand why Frazier has a weight problem.
"I get up at 5 every morning and take him for a walk. And he's on overweight management dog food. I do try," she said.
Disney was the only cat on the walk, and she went in style. A 3-month-old yellow tabby, Disney rode in a Longaberger basket carried by her owner, 12-year-old Danielle Dietrich.
Disney raised $25 in pledges.
