Liu, according to attorneys, was on a visa from China and staying in the country with Sit in order to learn his dog-training techniques.\n\nCountless social media videos posted on the Happy K9 Academy accounts showed the pair interacting with dogs at or near a park close to his Irvine apartment. Families would turn their dogs over to Sit for weeks at a time, at a cost of up to $1,000 a week, for him to train their canines.\n\nOn June 12, 2025, a dog, Shadow, died in Sit’s care. Nearly a week later, on June 18, 10 other dogs also died in Sit’s care: Ziggy, Miko, Rosie, Theo, Puffin, Cody, Zoe, Luna, Bang Bang and Saint.\n\nThe exact details of the dogs’ deaths are unclear, [even after a two-week trial](https://www.ocregister.com/2026/06/01/irvine-dog-trainer-on-trial-for-deaths-of-nearly-a-dozen-canines-in-his-care/). But evidence showed that Sit and Liu split up and dropped the dead dogs off at pet crematoriums across Southern California. Sit then texted the shocked owners, telling them their dogs had died unexpectedly, but peacefully, overnight.\n\nInvestigators retrieved the bodies of nine of the canines before they were cremated. Eight had died of heat stroke, a ninth of blunt-force trauma.\n\nProsecutors told jurors that some had blood on their faces, fur or paws.\n\nAn Irvine officer who spoke to Sit detected the smell of bleach in his van, which was full of dog carriers. That led prosecutors to allege that the dogs died in the vehicle, which they described to jurors as a “death bed.”\n\nIn all, Sit was found guilty of a dozen felonies and several misdemeanors.\n\nThe defense denied that the trainer was responsible for the deaths of the dogs, and told jurors there was no evidence the canines died in the van.\n\nLiu was simply doing what Sit told her to do, her attorney said. The defense acknowledged that both made mistakes after the dogs died, but denied they broke the law.\n\nSit and Liu will return to court for sentencing on July 10. Both have remained behind bars while awaiting trial.\n\nHe faces a possible 13-plus years in prison. She will be released for time served, her attorney said.", "url": "https://wpnews.pro/news/california-dog-trainer-convicted-in-deaths-of-11-dogs", "canonical_source": "https://www.mercurynews.com/2026/06/18/irvine-trainer-54-convicted-in-deaths-of-11-dogs/", "published_at": "2026-06-18 15:50:25+00:00", "updated_at": "2026-06-18 15:54:29.837449+00:00", "lang": "en", "topics": ["ai-ethics"], "entities": ["Kwong Chun Sit", "Tingfeng Liu", "Happy K9 Academy", "Orange County Superior Court", "Shadow", "Ziggy", "Miko", "Rosie"], "alternates": {"html": "https://wpnews.pro/news/california-dog-trainer-convicted-in-deaths-of-11-dogs", "markdown": "https://wpnews.pro/news/california-dog-trainer-convicted-in-deaths-of-11-dogs.md", "text": "https://wpnews.pro/news/california-dog-trainer-convicted-in-deaths-of-11-dogs.txt", "jsonld": "https://wpnews.pro/news/california-dog-trainer-convicted-in-deaths-of-11-dogs.jsonld"}}
