I didn't save any puppy teeth...any teeth that aren't in a mouth gross me out lol...but my sister saved her dog's so you are not alone.
I do still have Gus' first toy bunny that has been torn to shreds. It's a mess. He can no longer play with it but I can't get rid of it. It reminds me of bringing him home and that he was about the same size as the tiny toy.
