Sinkhole in Florida swallows two houses

(NBC) - A massive sinkhole has swallowed at least two homes in Pasco County, Florida.

Video shows a sinkhole forming and destroying one of the homes on Friday morning.

Officials say the sinkhole started as the size of a small poll and gradually became bigger.

No one was in the house at the time, but firefighters did rescue two dogs that were inside the house.

At least ten other homes have been evacuated for safety reasons.
