Canine (fang) teeth usually erupt between 5-6 months of age. Since Daisy is not quite 5 months old yet, the chance of her having a fully erupted adult canine tooth is quite slim. The tooth in the picture looks much more like a baby tooth than an impressively large adult canine tooth in a dog her size. With that said, I'd still recommend having your vet perform a full oral exam on Daisy during her next visit. They may also recommend taking dental x-rays to be sure that the full tooth root came out, as retained roots can be problematic. Odds are good that her tooth was already just a little bit loose and this rough playing just sped up the process. It's always better to be safe than sorry!
