help with puppy

[fast gt]

I know this doesnt have anything to do with a car thread but how do you stop a puppy from whining at night cause i brought a puppy sat and she hasnt stopped whining at night. if i go see her she is quiet but as soon as i leave she starts again, i slept in the lounge with her and didnt hear a noise out of her ive tried putting a teddy with a ticking clock under it but that doesnt work ive also put toys and food in the room with her any help would be great cause i miss sleep
