The canine, whose name is Sanchez, has no coaching experience but does like to play with his own balls.
A source close to the Bichon Frise confirmed the dog will take over first team duties from Malky Mackay.
The source said: “Mr Tan wanted a manager who could follow simple commands and lick his face like it was made of buttercream frosting.
“Sandy fits that bill. He is a needy little dog who can make things happen for Cardiff. He can’t wait to get started.”
Mr Tan reportedly only speaks to people once they have rolled over, had their tummies tickled, and surrendered themselves to the will of the Malaysian industrialist.
A spokesperson for Tan revealed he is a self-confessed lunatic who is obsessed with the idea of fighting Joseph, the mysterious carpenter who deflowered the Virgin Mary.
“Mr Tan likes the idea of climbing to the top of a great mountain and fighting God’s step-father. Once the carpenter is defeated then Mr Tan would become the legal guardian of God himself.”
