Strict liability for a dog at large, the one-bite rule otherwise
West Virginia's dog statute, W. Va. Code 19-20-13, makes an owner or keeper who permits a dog to run at large liable for the damages it inflicts. Summaries describe a two-track system: strict liability if the dog was at large, and the one-bite rule if it was on the owner's property or restrained.
Keeping a known vicious dog is addressed in 19-20-20, and the deadline is two years.
