Two pit bulls that attacked and killed a horse last month have been euthanized.

Lanier Orr, who runs the animal shelter for Forsyth County, confirmed Monday night that the dogs had been put down.

The animals were quarantined Oct. 11 after they were discovered attacking a 14-month-old horse in a pasture on Watson Road.

When Forsyth County Sheriff’s deputies arrived, one of the dogs was still attached to the horse’s mouth.

The 750-pound horse lost so much blood that it went into shock and died later that night, authorities have said.

The owner of the dogs, Melissa Andrews, was cited with one count of failure to vaccinate and two counts of animal at large.

Authorities said the dogs had been kept in the basement of the woman’s Watson Road home, not far from the pasture where they were found.

The attack occurred after they somehow got out of the basement and ran over to the field.
