I remember with my last puppies when I saw a tooth on the rug. I panicked as it was huge I assumed it was an adult canine tooth. So Douglas & I went frantically round all the adult dogs checking their mouths but nothing. Then I thought to check the puppies and right enough it came from Chance - he now has really long adult canines!! They do like to keep us on our toes and frighten us from time to time.
We keep Benji's teeth in an old camera film spool case.
