The Animal Rescue League and Massachusetts State Police are now investigating the alleged crime.

The picture snapped by a Brockton, Massachusetts, man and posted on Facebook drew instant criticism. People quickly began posting their objections and flooding the towing company with calls.

Apparently, the two people in the van being towed were in the cab of the tow truck and that's why the dog was chained to the bed. The dog is owned by the driver of the truck.

The man who took the picture, Mike Gerry, also has a dog: Molly.

Mike says he saw the dog on the flatbed while driving down Route 128 near Route 2 on Wednesday. He beeped and tried to get the tow truck driver’s attention but had no luck.

"I posted it on Facebook for my buddies to put it out there. and it went unreal, it went ballistic," Gerry said. "And ever since then people have been commenting on it, 'you're doing the right thing.'"

To be clear the company told WFXT the dog being chained to the back of a flatbed truck is not their policy. The driver has reportedly been fired and the dog is OK.

The company also says it is donating $1,000 to the MSPCA and has set up a call center so it can answer and return every single call about the incident.
