Many dog owners in Chicago love to hang out in Fred Anderson Dog Park with their furry friends. A woman named Deborah recently brought her pup there and was ready for another normal day… but it was all but that. That same Thursday morning, an unnamed man arrived to leave his dog completely unattended there. Deborah and the other park-goers were unable to believe what they witnessed. It’s reported that the dog, who had no tags or ID, looked visibly nervous and confused as he watched his human walk away without him. The witnesses became more and more concerned as the minutes passed — so they called for help a local animal rescue.

“I felt he was abandoned,” Deborah told CBS Chicago.

Over 30 minutes later, the man came back. That’s when Deborah pulled out her phone and confronted him on camera.

The man didn’t want to listen to what she had to say, but Deborah refused to let him go without trying to teach him a lesson.

She fought an onslaught of verbal abuse from the angry man, but she says her only concern was for the dog. “The dog park is not daycare,” she said on Facebook. “Another owner said that she has seen him do this before. Leaving the dog alone like this was irresponsible and dangerous for it. It was obviously stressed that the owner did this as it was constantly at the gate looking for him; one time getting out into the entrance fenced in area.”

Watch the video below to see this unbelievable confrontation. Please pray for these animals that have owners who treat them this way.
