What should you do if a dog chases you while bike commuting?
If a dog chases you on your bike commute, keep control of the bike first: hold your line, watch traffic, and do not swerve into a lane. If the dog is close, stop where it is safe, dismount and keep the bike between you while you speak firmly. Once the dog backs off, walk the bike away. Report the dog and address to animal control, and adjust your route if it happens again.
On the way to work
01Protect yourself from traffic first
In a city, the danger is less the dog and more the car behind you when you swerve. Check your mirror or shoulder before you change position, signal if you slow, and move toward the curb or a driveway rather than into the lane.
02Stop and use the bike as a barrier
If the dog is at your wheel, stop safely, get off on the far side and keep the bike between you. Stand still, avoid staring, and tell it "No" or "Go home" in a firm, deep voice, as the CDC recommends for an unfamiliar dog. Panniers and a loaded rack make the bike a wider barrier, but also slower to walk, so keep both hands on it.
03Get the owner involved
Commuter routes pass homes and businesses, so the owner or a neighbor is often close by. Call out for help. A person calling the dog back usually ends it quickly.
04Walk clear, then ride
Once the dog stops, walk the bike away until you are well past the property. Starting to ride too soon can set off the chase again.
05Deal with any bite before you carry on
Do not just push on to work. Clean the bite right away with soap and water, and the CDC's rabies guidance is to keep washing for 15 minutes, so a gas station or office restroom is fine. Then see a healthcare provider if it is deep, gets infected, the dog's rabies status is unknown, or your tetanus shot is more than five years old. Tell work you will be late; this is not a wound to ignore until evening.
06Report it and change the route
Commuters pass the same houses twice a day. Write down the address, the time and a description of the dog, or take a photo once you are safe, and report it to animal control. Take a different street until the problem is fixed. Some dogs are loose only at certain hours, so the evening ride may differ from the morning one.

How do I know a dog is about to bite?
The ASPCA lists bared teeth, growling, lunging, a stiff body with ears forward and a direct stare. A dog showing these at the curb is worth slowing for early, while you still have room to stop safely and a gap in traffic.
