The search for six dogs reportedly stolen out of the back of a pickup truck at a Langley park appears to have ended with a shocking and tragic twist.

According to Petsearchers Canada, which was helping in the investigation, the woman who was walking the dogs has allegedly admitted to leaving the animals in the back of the truck on a hot day – and that all of them died of heat exhaustion.

“The dogs had water, the side vents on the vehicle were open, nonetheless it was a very hot day and they perished,” said Petsearchers spokesman Al MacLellan.

"I'm just devastated for the families," said Petsearchers' Alesha MacLellan. "Throughout the whole search there was always a glimmer of hope that perhaps one or two of the dogs was okay somewhere.”

The allegations have not been confirmed by police.

The dog walker had reported the dogs were in the back canopy of a pickup truck while it was parked at Brookswood Dog Park near 206 Street and 44th Avenue.

At the time, the dog walker told police she had left the truck briefly so she could use the washroom and the dogs were gone when she returned. She said the back canopy had been unlatched.

Attempts to reach the dog walker for comment have proved unsuccessful.

According to their website, Petsearchers Canada is "a Vancouver area based Pet Detective and Bloodhound tracking service committed solely to the task of reuniting lost and stolen pets with their loving families."
