Renton dogs just got a bit cozier this fall.

When Fairwood’s Nancy Heintz couldn’t find a coat she liked for her Dachshund, she decided to start a business that made the jackets cuter and warmer than what she found in stores.

Heintz is one of about 40 local vendors who plan to set up shop at the Renton Fall Harvest Festival Saturday.

While the summer farmers market focuses on perishable goods, the annual festival allows crafters to show their wares.

“There’s all sorts of different people at the market,” said Heintz, who started DOGEDUDS with her sister in October of last year.

Given the economy, business has been slow, she said. “People aren’t indulging on their pets right now.”

But the sisters are slowly breaking into the market at smaller stores, including Renton’s Poodie Pet Parlor.

“We really want to get into the pet stores,” Heintz said.

The two started the business by experimenting with a sewing machine and by cutting out patterns based on a coat Heintz had purchased.

Their velcro is longer and their fleece is thicker than what’s typically found with most dog coats, she said.

They’re also all reversible. One side always has a water resistant fabric, and the other has patterned fleece or cotton.

The sizes range to fit most dogs from designers to labs. Prices range from $20 to $60.

The idea for DOGEDUDS started with the two sisters and picked up speed when their large family found out.

The Heintz hosted a large Thanksgiving dinner, where relatives fell in love with the dog coats and bought about 10 of them, said husband Jeff. “They all thought they were great.”

A nephew then introduced Heintz to their first big customer, a pet store on the beach in Cambria, Calif.

Heintz designed a jacket for the warm beach weather, replacing the fleece with a cotton surfboard-themed fabric.

The sisters have since hired a seamstress to make the coats, although Heintz still chooses the fabric, she said. “I love picking the materials and patterns.”

DOGEDUDS is one of several crafters expected to have their goods for sale at the Piazza Park Saturday.

“We’ve got a really nice variety of vendors,” said organizer Susan Bressler.

Kids will have a chance to paint a mini pumpkin for free, and a fortune teller will be giving readings.

Next door the Renton Chamber of Commerce will also have about 70 booths for its annual Business Expo.

“It’s a nice cross promotion,” Bressler said.

The festival is expecting about 2,000 to 3,000 guests, depending on the weather.

“It’s just a way to get people downtown and involved in the community,” she said.
