San Antonio firefighters rescued around a dozen animals from fast-moving flames that engulfed a North Side apartment complex on Friday.

The fire originated at around 10:30 a. m. in the second floor of the Canopy Apartments Complex on the 900 block of Bitters Road. The fire spread quickly and affected 24 units, most of which are occupied.

As of noon, the San Antonio Fire Department had dispatched 35 emergency units to the complex. Authorities closed part of Bitters east of U. S. Highway 281 to traffic to facilitate firefighters in dousing the fire.

Carlos Macias and Christian Villarreal saw the growing flames and pulled over before the firefighters arrived at the scene. They started kicking in doors to let people, who might be trapped, know about the fire and escape. Speaking about the fire incident, Carlos said, "The ones that were in the kennels seemed pretty happy to see me. But there was a couple of dogs that were pretty scared once they saw we were trying to get 'em out, they seen the smoke, they just kinda got out on the door."

No injuries related to the fire were reported. However, people credited firefighters with saving their pets.

Meanwhile, investigators are trying to determine the cause of the massive fire.
