The four dogs that mauled an 18-month-old boy in his backyard on Monday were euthanized Tuesday.
Four Boxers that belonged to his grandparents attacked Chance Walker Jr. at his home near Lake Worth late Monday afternoon.
For Worth Animal Control, which has a contract agreement with Tarrant County, took the Boxers into custody Monday.
The agency said the dogs, Boxer mix breeds, would be euthanized Tuesday evening in part because of the age of the victim and the severity of his injuries. The state health department also recommended that dogs be tested for rabies, an action that requires the animals be euthanized.
Tarrant County sheriff's deputies said the Walker crawled through a dog door into his backyard while his parents were sleeping.
A neighbor made a frantic 911 call and told dispatchers how badly he was hurt.
"It's just a big hole in his face," she said.
The Tarrant County Sheriff's department confirmed Tuesday that eight separate calls about dangerous dogs in the neighborhood were made in the last two years. The department said deputies have fewer options in unincorporated areas but is reviewing the calls to see if more could have been done to prevent the attack.
The boy's grandmother, Lena Walker, bonded out of the Tarrant County Jail on Tuesday afternoon. She was arrested on suspicion of assault after a confrontation with a neighbor after emergency crews arrived at her home.
Walker told NBC 5 she did know how her grandson was doing or how the attack happened.
