A callous Arizona man waved at a his elderly dog as he abandoned him in a crate outside an animal shelter in the sweltering heat.
The reckless owner dumped the defenseless animal the gate of Pinal County Animal Care and Control in Casa Grande.
The elderly dog sat inside the crate for two hours in 85-degree heat with no water, the shelter said.
Heartbreaking video shows the moment the pooch, named 'Little Dude' by the shelter, was ditched outside the gate.
The man then waved to the camera before taking off in his car. He was seen wearing a white shirt, shorts, and sunglasses.
