A 4-year-old Texas boy is dead after police say his family dog latched onto the child’s neck and shook him to death.

KSAT reports that Noah Trevino was in the backyard of his home off of Twincreek Farm in Converse when the dog, a “large mixed breed,” attacked him. According to police, the dog, who was tied up at the time, clamped his mouth on Noah when the boy moved too close to him.

“It appears that the child may have gotten too close to the dog,” Bexar County Sheriff Javier Salazar said. “One of the relatives of the child actually looked out into the backyard and saw that the dog had his mouth around the little boy’s neck and was shaking him.”

Family members found the boy unconscious and attempted unsuccessfully to revive him with CPR, according to NBC4. Paramedics arrived and airlifted to boy to University Hospital, where he died from severe injuries.

“This was a family dog,” Salazar added. “Even if the dog doesn’t show any outward signs of aggression, sometimes they can be unpredictable. So, it’s best to always be vigilant when you’re dealing with a small child and a dog like that.”

Authorities took the dog to Bexar County Animal Control, where he’ll be checked for rabies, then euthanized.

Meanwhile, a family friend set up a GoFundMe account to help cover the boy’s funeral expenses.
