O'FALLON, Mo. - The O'Fallon, Missouri, Police Department is asking residents to be on the lookout for a "dangerous dog at large."

According to officials, a dark-colored Bull Terrier mix was involved in an attack on three people inside a home Friday morning, resulting in two being hospitalized with serious injures.

Officers avoided shooting the dog due to other occupied homes as the backdrop, the department noted.

The dog was last seen running towards Galaxy Drive near Veterans Memorial Parkway.

Anyone with information on the dogs whereabouts is urged to not approach and to call the O'Fallon Police Department at (636) 240-3200.
