"We love our dogs and each of our team is trying to personally cope with this terrible loss," Playful Paws said on its Facebook page. The centre did not immediately respond to a request for comment.
It is not immediately clear how long the heat was on before the dogs died or whether the centre would compensate the owners. Local police said the incident does not warrant the involvement of law enforcement.
