A horse abandonment case in Washington has attracted a $US2500 reward from the Humane Society of the United States.
The money is offered for information leading to the identification, arrest and conviction of those responsible for abandoning five horses on a logging road in Pierce County on November 12.
Local resident Terry Cairns found five emaciated horses deep in the forest outside of Elbe, Washington, during a bitter rainstorm.
"The horses were cold, injured and horribly malnourished," the society said. "It appears they were afraid to leave the area where they were dropped off, and could have been stranded for up to two weeks.
"Of the five found, one was so emaciated that he had to be euthanized on site.
"Two of the surviving horses are estimated to be at least 15 years old and another is suspected to be pregnant. Abandoning animals in Washington state is a misdemeanor and is punishable by up to 90 days in jail and/or a $US1000 fine.
"Abandoning a horse is not only irresponsible, but it is also against the law," said Dan Paul, The society's Washington state director.
"Struggling horse owners do not need to turn to abandonment to solve their problems. Rescue groups, online adoption programmes, lease arrangements and even humane euthanasia are all responsible alternatives to horse abandonment."
