Pit bull pair kills goats, sheep after late night dig into Little Rock Zoo

LITTLE ROCK, Ark. (AP) -- The Little Rock Zoo says two dogs burrowed under a fence and killed five animals in the children's farm area overnight.

The zoo says the pit bull and pit bull-terrier mix apparently dug under a fence that surrounds the perimeter of the zoo and killed four goats and one sheep. The zoo says the dogs ran away and went back under the fence when approached by zoo staff members Thursday morning.

The zoo says several other animals were injured and are in the care of the zoo's veterinarian.

Officials say the zoo regularly inspects the perimeter fence for holes and re-inspected the fence Thursday morning to ensure no animals could get in.
