He doesn't even have a name, but he has a story.
Unfortunately, no one knows it. The tan and white Staffordshire bull terrier mix was found as a stray last week and taken to Maricopa County Animal Care & Control (MCACC) East in Mesa, Arizona, on Friday. And it's clear that life on the streets didn't prepare the unlucky dog for the city shelter.
A video taken by volunteers shows the dog's frightened response to life at MCACC. With dogs barking and howling in the background, the frightened terrier cowers in the corner of his little cell, dipping his head and staring at the wall as he tries to disappear. Overcome with anxiety, his legs shake uncontrollably beneath him.
