PLEASANTON -- A Pleasanton couple was arrested Friday after their dog bit their 5-year-old son in the face twice in the last three months, according to police.

According to Lt. Jeff Bretzing of the Pleasanton Police Department, 36-year-old Marc Kornberg and 27-year-old Dublin resident Lila Myrvete were arrested by detectives Friday. The pair face charges of child neglect and endangerment after their son, who has not been identified, was bit in the face twice by his father's dog, a 96-pound Presa Canario, once in May and once in March.

Bretzing said Pleasanton police were called to the apartment on Bernal Avenue on May 19 to investigate the dog bite; officers soon discovered the previous biting incident, on March 6, which had gone unreported to police.

Kornberg's son suffered multiple facial injuries in the May 19 incident; he was transported to a hospital and later released. On March 6, he had been treated for similar injuries and released.

Police said that in both cases, the child had been left alone in a room with the dog. Prosecutors issued felony warrants for Kornberg and Myrvete, and the child was placed with Alameda County Child Protective Services.

The dog, whose name is "Boston," was taken to the Alameda County Dog Shelter in Dublin, where it underwent home quarantine and was later released without any issues.

On May 28, a public dog hearing was held in Pleasanton and a judge determined the dog to be vicious. Kornberg was ordered to relocate the dog to a rehabilitation and training facility in Ohio or to have the animal euthanized, per the city's municipal code. Kornberg chose to send the dog to Ohio.

In 2001, Diane Whipple, a lacrosse coach at St. Mary's College, was mauled to death in the hallway of her San Francisco apartment building by her neighbor's two Presa Canario dogs. The dogs' owners, attorneys Marjorie Knoller and Robert Noel, had adopted the dogs from a gang member who was serving a life sentence in Pelican Bay State Prison

A jury found Knoller and Noel guilty of involuntary manslaughter. Knoller, who was handling the dogs on the evening of the attack, was also convicted of second-degree murder. Noel served two years of a four-year sentence; after a lengthy appeal, Knoller was sentenced to 15 years to life for the murder conviction in 2008.
