They thought it was cute to make a video showing themselves pouring boiling water over a dog – before being attacked in the streets the following day.
The footage starts with the two pals playing around as the dog lies on the floor near them.
One of the youths then carries a washing up bowl full of hot water and pours it over the animal while his friend swears at the dog, repeatedly calling him a “little p***k”.
One is heard saying: “Look at the steam coming off him” and both start laughing hysterically.
The video then cuts to a second clip, which is filming the entrance to a house, as a male voice says: “Listen everybody, these are them guys that hurt that dog.”
He claims the men are the boys’ dad and uncle – although that is not confirmed.
The boys are then dragged onto the pavement and wrestled to the muddy ground by the men.
One then splashes a bucket of water over one of the boys.
After the video was posted to Facebook, people praised the men for their response.
Marie Otley, from Leeds, wrote: “Well done to the two men who got them back. That poor dog. What goes around comes back around.”
Lynn Carrington added: “Well done the guys who did this, respect. I hope the dog goes to a better home.”
Maureen Stewart wrote: “Well done. So deserved. Just hope the dog wasn’t hurt too much.”
