Police arrested an Arizona man after he allegedly spent two months trying to set up a sexual encounter with a dog over Craigslist.

What 47-year-old James Naylor didn't know is that he wasn't talking to a willing dog owner -- he was talking to an undercover officer.

The married father, who lives in Mesa, allegedly posted an ad on Craigslist at least two months ago titled, "Bottom need hung tops -- M4M" and "Willing to try hung K9 4 Fun too," according to ABC 15. An agent with the Maricopa County Sheriff's Department negotiated with Naylor for weeks, using a picture of a dog from the animal shelter (above) to lure him into a nearby hotel.

Naylor was arrested and taken to jail Monday night. He never saw the dog.

Sheriff Joe Arpaio told Fox 19 that he's seen this type of crime on the Internet before. Six people were arrested over the past year for similar offenses in which Craigslist was used to solicit animal abuse.

"This is a different breed of people who would do this to dogs. We are going to continue this type of investigation; we are the only ones doing this but we are not going to stop investigating bestiality of this type, having sex with dogs," Arpaio said.

  • Suspect Sought In Sexual Assault Of Horses

    An owner and breeder of world class miniature horses in Florida is hoping video surveillance footage will help identify the person suspected of sexual assaulting several of her horses and killing her watch dog. The brutal sexual assaults have been ongoing since May 2012, according to the horse owner, Abby Conder, of Marion County. On Dec. 30, 2012, Conder got her first glimpse of the alleged perpetrator when she reviewed video footage from inside her barn that was recorded earlier that morning. "Someone's got to know this man," Conder said. "He's been in this area at least 8 months now. These are babies I have raised and it's affected them psychologically. It's hard to get in a stall with them and I can't get near their rear ends to put a harness on them." Anyone who recognizes the subject in the video or has information about the animal sexual assaults is asked to contact the sheriff's department at 352-732-8181.
