Is this a broken tooth or just a lost baby tooth?

So I'm kinda sure this is just a normal puppy tooth but I'm just looking for a quick confirmation. I took this out of my four month old puppies mouth a bit ago. I noticed she was licking her mouth a bit so I took a peek inside and saw it dangling. She allowed me to pull it out which happened easily and seemed relieved afterward. Is this just a normal loss of baby tooth or a broken tooth?

Thank you
