CHULA VISTA (CNS) - A fire at a Chula Vista home Wednesday displaced five residents and killed one of their two dogs.
   
Firefighters sent to the single-family home on Myra Avenue near East L Street around 3:45 a.m. found smoke and flames coming from the garage. Crews had the blaze knocked down about 20 minutes later, according to the Chula Vista Fire Department.
   
The fire left three adults and two children displaced, but none of them were injured, Chula Vista Deputy Fire Chief Harry Muns said. Firefighters working to extinguish the flames rescued one of the residents' dogs, but their other dog died.
   
The cause of the fire was under investigation. 

Muns could not immediately confirm reports that ammunition kept in the garage had exploded.
