SEATTLE — It’s a breezy morning in March at the Fremont Sunday Market, and people with canines are out in full force. A great dane, golden doodle and a husky walk by within minutes of each other. There's a sweater-wearing pug ahead. It trots up to a baby-blue food truck and promptly puts its paws on the step.

Clearly, the pooch notices the “doggie $5 sundae” sign. Luckily, his owner sees it, too. Not only that, but there’s also bacon pupcakes, air-fried chicken hearts and paw-shaped peanut butter cookies to choose from. Plus, you can pre-order doggie bow ties and dog birthday cakes served up on frisbees. You know, for yappy hours and bark mitzvahs.

Turns out, this 1968 Chevy Step van turned food truck is known as The Seattle Barkery. The truck’s specialty is handcrafted treats for dogs, but there are a few bites, like banana bread and scones, for us humans. Cats aren’t left out, either. Treats for felines include chicken hearts and cod skins.

Surprisingly, this is not the only dog-focused food truck around. These mobile pet treat trucks have popped up across the country. Just like your typical food trucks, you track them down via their websites so you can visit them at festivals, dog-friendly breweries and dog parks.

“Our rescue dog, Sherman, was the official treat decider when we first launched,” says Dawn Ford, owner of The Seattle Barkery. “He’s a very picky Pekingese mix. If he didn't like it, it was off the menu.”

Fetch: Sweet pup treats in Alabama

In Birmingham, Alabama, keep your eyes peeled for Fetch, a pink food truck serving up doggie ice cream, popsicles, ice-cream sandwiches and decorated cookies.

“One of my favorite customers is a sweet little dog named Bruno,” says Fetch owner Allison Whitfield-Smith. “He is used to seeing me at the farmers market, and one day, when he thought I was supposed to be there but couldn't, his owner told me he ran over to my regular spot and just started barking.”

Winnie Lou-The Canine Company: Sourcing local in Colorado

It’s a food-truck trend that dogs drool over. Just ask Ashlin Cook, owner of Winnie Lou-The Canine Company, based in Boulder, in Colorado.

Her energetic bird dogs, Winston and Louis, go nuts for her homemade treats, including the pumpkin spice cookies, peanut-butter sorbet and bison burger jerky, made with only three ingredients: bison, organic flax seed and cranberries. Her promise is to always work with local family farmers to secure high-quality ingredients and to never add sugar, preservatives, salt, wheat, soy, corn or dairy.

4 Paws Pastries: A culinary degree used for the dogs in Tennessee

For Kinsey Smith, co-owner of 4 Paws Pastries in Spring Hill, Tennessee, making treats for pups was a no-brainer. Thanks to her culinary degree, she’s perfected plenty of goodies like pumpkin pupcakes, a fluffy, grain-free cupcake topped with a maple cream-cheese frosting; peanut butter based donuts topped with a yogurt glaze and sprinkles; and special-occasion canine cakes (for barkday parties, of course).

Bow-Wow Bones: Yappy hours in Texas

Signature treats at Bow-Wow Bones in Austin, Texas, include locally made ice cream, blueberry waffles, coconut chicken and kangaroo jerky. You’ll most often find this truck at private parties and “yappy hour” events at apartment complexes.

“Austin has the hottest food-truck scene in the U.S.,” says Lara Enzor, owner of Bow-Wow Bones. “Food trucks were just starting to emerge in 2012, and I thought it would be really fun for Austin's dogs to have their own food truck.”

In other words, your dog’s lunch will never be the same.
