Pet owners rejoice:You can now bring your furry friend along on Uber rides—for a $6 dollar fee.

The company’s latest feature, Uber Pet, charges an additional flat rate to request a driver who’s willing to transport pets. The feature was introduced in other U.S. cities, including Austin, Philadelphia, and Denver, back in October, but debuted in the District on Wednesday.

After entering a pickup and drop-off location on the Uber app, riders can now be matched with an animal-friendly driver by using the “Choose a Ride” option.

The service is limited to one “small animal such as a dog or a cat,” according to Uber’s website, but there’s no restriction on breed or size. You may have to leave your ten-foot boa constrictor at home, but your German Shepherd or Yorkie can ride.

Can you bring more than one pet aboard? That’s up to the individual driver, according to Uber’s website.

Uber Pet could carry some additional costs. If your pet makes a mess, riders are on the hook for an additional charge. Excessive hair, waste, or damages to the vehicle could make the rider subject to a cleaning fee.

Dr. Lee Morgan is a veterinarian at Georgetown Veterinary Hospital on M Street with lots of elderly clients—animals and pets alike.

“This is going to be huge for the cat-owning community especially. I’ve got elderly clients who have trouble arranging rides for their animal’s care,” says Morgan. “I don’t know if you’ve ever tried to put a cat into a box, but that’s stressful enough, so this is great.”

Morgan says his patients have had problems with taxi drivers barring service dogs and hopes a service like Uber Pet will help.

“I’ve had to flag down cabs and tell them they’re legally obligated to let seeing-eye dogs ride,” he says. “As a vet, this will allow my older clients and clients with mobility issues to get here more easily so I’m very appreciative.”

Service animals will still ride free of charge. Uber is compliant with the U.S. Service Animal Policy and all drivers have a legal obligation to give rides to customers with service animals regardless of whether the ride is an UberX, Uber Pool, or another type. (Service animals are not required to wear a tag, be registered, or display any kind of proof. By law, drivers cannot request documentation, and are only allowed to ask two questions to determine if the rider has a qualifying service animal: “Is the animal required because of a disability?” and “What work or task has the animal been trained to perform?”)

Despite these anti-discrimination policies, both Uber and Lyft drivers have been known to deny customers with service dogs in the past.

Disability advocate Ryan Honick says he and his service dog Pico are regularly denied rides by Uber and Lyft drivers despite the law. According to records Honnick requested from Lyft, he says he was denied a ride 75 times in the last year alone. 

“I have to build rejection time into my itinerary,” he told DCist. “I expect three or four drivers to reject my ride request before I get a yes.” 

The ADA prohibits companies like Uber from charging handlers for shedding from service animals, but Honick says he’s had to dispute trumped up cleaning fees from drivers (he thinks the additional cleaning fee for Uber Pet is ripe for abuse by drivers).

He says he doesn’t believe the change will increase the number of fraudulent service animals.  “The reality is that the abuse of the system will always be there. Putting policies aside, there will always be people ready to take advantage of the system.”
