Seven pit bulls killed a Brazilian man after mercilessly attacking and ripping his face.

The deadly dogs ambushed the 46-year-old Aglacir de Macedo Pereira in a rural area of Lageado Feio, Southern Brazil on Feb. 2.

An online tabloid said the man was out for a routine morning walk when the vicious dogs escaped from a farm beneath a fence.

Passers-by bravely saved him from the gruesome assault and dialed 911. They then assisted him on his way down the road to the emergency vehicle.

Pereira was airlifted more than 20 miles to Santa Cruz Hospital in central Pinhao. The pit bulls had bitten off all of his face muscle, exposing his skull entirely.

He sadly died as a result of his injuries shortly after arriving at the hospital.

"He was like a son. I raised him since he was two years old," Pereira's distraught aunt told local media.

His family has accused the dogs' owner of failing to adequately confine the animals.

The dogs' owners are yet to be revealed. The attack is being investigated by police, and the owner may face charges.

Pereira's aunt advised all who own these animals to look after them. "We do not want other people to go through a situation as sad as the one we are going through," she continued.

Battersea, an animal rescue organization in London, suggests that dogs should socialize with other dogs and people from a young age to prevent Pereira's incident. Daily walks would give your dog a change of scenery and the opportunity to socialize with other dogs, they added.

The organization also noted many unruly young dogs aged six to 18 months. These dogs, they say, had received no training as puppies and had become too much for their owners to manage. A training class will assist new owners in taking the proper training approach.

Battersea also suggests keeping the dog on a leash at all times in new environments. The group explained that pets can easily be frightened by the noise and could injure themselves or scare other people. Hence, fur parents should make a safe area if the dogs are new to the place.
