Shuttlesworth, 51, weighs 230 pounds. Lola, who was 5, weighed just four-and-a-half pounds.
The former screenwriter was arrested Saturday morning at his Queens, New York home. He is alleged to have delivered the fatal blow last May 29.
Shuttleworth took his pet to a veterinarian after she suffered a traumatic injury. The vet became suspicious of the dog's injuries and contacted the ASPCA. The ASPCA performed a necropsy and then contacted authorities.
Joseph Pentangelo, a spokesperson for the ASPCA, told the New York Post
Lola sustained a traumatic brain injury secondary to the application of blunt force to the right side of her head at the hands of the suspect, her owner.
Whatever made Shuttleworth angry enough to deliver a blow to the poodle's face is not known.
According to the Internet Movie Database
, Shuttleworth wrote an episode of the hit TV series, NYPD Blue
in 2000 and an episode of Cover Me: Based on the True Life of an FBI Family
The Daily Mail
reports Shuttleworth now works as an administrative assistant at the University of New York and reads scripts for $300 each.
If convicted, the former screenwriter faces up to a year in jail.
