I just finished posting our article about cyclists using Virginia's dangerous dog law:
Under Virginia law, any dog that causes injury can be declared a dangerous dog, whether from a bite, or from a crash caused by the dog. Dog-induced crashes frequently result in serious injuries.
We've provided some hang tags for you to download and print, take with you on rides, and leave at homes where there are cyclist-chasing dogs. These are to advise the dog owner of the law, and the seriousness of having their dog declared a dangerous dog.
There's also an article explaining the law and how to use it, which you can link to, or download and print.
Please feel free to use this material on your own websites, etc.
