A dog was rescued from an apartment building in Milford that caught fire Sunday morning, fire officials say.

They say they were called about the fire at 278 Broad St. just before 11 a.m. The call came from inside the house.

Fire officials say someone who lives on the first floor smelled smoked and called 911.

They say there the dog was in the second-floor apartment when the fire started. Firefighters say they were able to force entry into the apartment to get the dog.

There were no other people in the second-floor apartment and no one was injured.

Fire officials say the building's age presented a challenge. They say they noticed the building was older because of its foundation and construction, which could make a fire spread faster.

Firefighters grabbed two hoses to tame the flames.

The first floor has extensive water damage, as well as smoke damage that reached to the third floor. The Red Cross is helping those who live in the building move.

Fire officials say it's key for residents to change the batteries on their fire alarms and smoke detectors.

The cause of the fire is under investigation by the Milford Fire Marshall Division.
