Irvine, California — A Southern California dog trainer has been convicted after prosecutors said he was responsible for the deaths of 11 dogs entrusted to his care and then attempted to conceal what happened by having their bodies cremated before owners could learn the truth.
The case has drawn widespread outrage among pet owners and animal advocates after investigators revealed details about the dogs’ deaths and the steps allegedly taken to cover them up.
On June 17, 2026, Kwong “Tony” Chun Sit, 54, of Irvine, was convicted of multiple felony and misdemeanor charges related to the deaths of 11 dogs who had been enrolled in training and boarding programs through his business, Happy K9 Academy.
Dogs Died While Under Trainer’s Care
According to prosecutors, the incidents occurred in June 2025 while the dogs were participating in training programs that often lasted several weeks.
Authorities said Sit left the animals confined inside small crates in a hot van, where they suffered fatal heat-related conditions.
Investigators later determined that eight of the dogs died from heat stroke, while another dog, a puppy, died from blunt force trauma.
The remaining two dogs were cremated before authorities were able to recover their bodies and conduct examinations. Among the dogs identified in the case were Rosie, Shadow, Ziggy, Miko, Theo, Puffin, Cody, Zoe, Luna, Bang Bang, and Saint.
Prosecutors Say Cover-Up Followed the Deaths
Rather than immediately notifying authorities or providing accurate information to pet owners, prosecutors alleged that Sit devised a plan to hide what had happened.
Authorities said Sit enlisted the help of his girlfriend, Tingfeng Liu, 24, of Vista, to transport the animals’ remains to multiple crematoriums in an effort to avoid suspicion.
Pet owners were reportedly sent similar messages claiming their dogs had died unexpectedly and peacefully.
One message sent to the owner of a dog named Miko stated:
“I’m so sorry to let you know that Miko passed away peacefully during the night while resting. There were no signs of pain or struggle, and it was truly unexpected.”
Investigators later concluded that those statements were false.
“These dogs did not die peacefully in their sleep,” Orange County Deputy District Attorney Danica Drotman said.
“These dogs did have signs of pain and struggle, unlike what Sit told the families, they suffered prior to their death.”
Investigation Revealed Disturbing Evidence
The case came to light after one of the pet owners contacted authorities, prompting an investigation by the Irvine Police Department.
Detectives were able to track down and recover multiple dogs’ bodies from different crematoriums connected to the case. Necropsy examinations revealed evidence consistent with heat stroke and other trauma.
Prosecutors said some of the animals were found with blood on their faces, paws, or fur.
Authorities also argued that Sit and Liu posed a flight risk when they were arrested, noting they were allegedly packed and prepared to leave when taken into custody.

Since their arrest, both defendants have remained jailed on $550,000 bail and were ordered to surrender their passports and avoid contact with animals and victims’ families.
Convictions and Potential Prison Sentences
Sit was convicted of:
- 11 felony counts of animal cruelty
- Seven misdemeanor counts of attempted destruction of evidence
- One misdemeanor count of destruction of evidence
Liu was convicted of:
- One felony count of accessory to a felony
- One misdemeanor count of destruction of evidence
- Two misdemeanor counts of attempted destruction of evidence
Prosecutors said Sit faces up to 13 years and 11 months in prison, while Liu could receive up to four years behind bars.
Orange County District Attorney Todd Spitzer condemned the actions that led to the convictions.
“The greatest fear dogs have is that you will never return when you leave them behind, and because of the unbelievably cruel actions of Mr. Sit and Miss Liu, that fear became a tragic reality for 11 dogs who will never have the chance to reunite with their families.”
For the families involved, the convictions mark an important step toward accountability, though many continue grieving the loss of beloved pets they believed were safe in professional care.
