Sound Transit Pet Policy Pilot Program Update
Seattle — Nearly two weeks into Sound Transit’s pilot program testing new pet rules for Link light rail, Sounder trains, and ST Express buses, an incident has occurred involving an injured train conductor.
On Tuesday afternoon, a leashed dog broke free from its owner on a Sounder train at King Street Station and attacked a service dog. The conductor was bitten while trying to separate the two dogs and received treatment for a minor injury.
The program, which runs through spring 2027, is designed to gather feedback on the new pet rules and assess their impact on safety and daily operations. Under the pilot, dogs must be on a short leash or in a carrier, while cats and smaller pets must remain in secure carriers.
Riders are required to:
- Control their pets at all times
- Clean up after their pets
- Keep animals out of seats, aisles, and doorways
Aggressive animals are never permitted, and service animal guidelines remain in line with ADA requirements.
Signage detailing the pilot guidelines will be posted at Sound Transit facilities soon to inform riders. Feedback from Sound Transit employees and security reports will help determine whether the new policy will become permanent.
The agency also notes that “pet travel is not guaranteed,” and staff may restrict pet travel due to safety, sanitation, or overcrowding concerns. Riders can report issues to Sound Transit Security via phone or text at 206-398-5268. A complete list of updated pet rules is available on the Sound Transit website.
