Authorities were called to a building fire in Santa Monica on Tuesday, reports ABC 7. They were able to contain the blaze within about 10 minutes. As crews searched the apartment, firefighter Andrew Klein found Nalu who had been overcome by heat and smoke. The dog was not breathing and had no pulse.

“He was totally lifeless,” Klein told AP. “I picked him up and ran out of the apartment because time is key, especially with a small dog … Failure was not an option.”
