MIAMI,Fla- The Rottweiler that mauled a 20-month old Florida boy to death on Saturday, has been euthanized after its owners relinquished custody to local animal service officers. Speaking to FOX affiliate in Tampa Bay,investigators said the dog, named “Willie,” killed Dallas Walters during a birthday party at a relative’s home, in nearby Pasco County.

Walters dropped a cookie on the floor, and when he went to pick it up, the dog attacked the boy.Walters was rushed to the hospital, but later died.

The dog, a 1 year old make had not been neutered, and its body has been sent to a local lab for rabies testing. His owners had owned the dog for two months, a local animal control official told WTVT.

A person who lives at the home where the attack occurred, declined to comment by the telephone, according to their report, the man replied ” stop bothering me,” and hung up on a reporter.

Excerpt From Walter’s Online Obituary :

He is survived by his father, Andrew Walters; his mother, Jessica Stafford; his baby brother Dallyn; and extended family members. Dallas was protective of his little brother, his dad said. He liked to fix up his blanket when he fussed and hold his hand. “He was the best kid,” Walters said. “There was no measure of life on this planet that added up to his. He was amazing. I couldn’t ask for a better son.” Dallas was typical for his age, and was known to play with a rubber ball in the house – sometimes bouncing it off his father’s head – and to mess with the knickknacks. But he also had a keen sense of order – like his mother, Walters said. He liked shoes to be in their proper place, picked up dirty plates and put them in the sink and would carry dirty diapers – his own or his brother’s – to the trash. “He had more personality than this world,” Walters said. “He had more personality than anybody claiming to be a personality on television. “He’s destined for greatness, either in this life or the next.”
