Houston streets are home to 1.2 million homeless animals, according to the city shelter BARC.
On the city's east end, residents consider stray dogs as more of a concern than crime.
There are so many animals in need, there isn't enough space to house them all.
Three Houston non-profits raise money to buy the food and medical supplies needed to care for these animals, right on the street.
And this weekend, "Forgotten Dogs of the 5th Ward", "Barrio Dogs" and Corridor Rescue are teaming up for the first time to host "Music for Mutts." The event will provide live music, food and information about spay and neuter programs.
Proceeds from ticket sales will benefit spay and neuter programs throughout the city.
FOX 26 News followed volunteers one morning and witnessed the heartbreak of these homeless animals first hand.
