“The investigation is continuing,” said Kerrville Sgt. Mary Krebs, who added that the owner was already under investigation because of a prior bite by the dog.
Rabies tests are being conducted on the dog, which reportedly weighed more than 100 pounds. Authorities say it was not registered as a dangerous dog.
The husband of Carol Williams, the victim, called authorities to their home on Mack Holliman Drive about 9 a.m. Sunday after the dog bit his wife on the arm.
He used a hammer on the dog to get her loose, said Krebs.
The dog escaped from the house and was running around the neighborhood when two deputies assisting police and EMS killed it when it approached, said Sheriff Rusty Hierholzer.
Kerr County Animal Control Officer Janie Whitt said the dog bit a neighbor in August and was quarantined and then released.
Whitt said it was then learned the dog had previously been declared dangerous in Travis County. Whitt said the owner should have registered the dog as dangerous when it was moved to Kerr County and secured $100,000 in liability insurance on it, but did not.
“The minute we found out this dog had been declared dangerous in Travis County, we wanted it investigated,” said Whitt, noting her staff referred to police details on the August attack, in which the victim nearly lost a finger.
