You arent the only one!
I have all of Tino's teeth in an empty pill bottle. I have the teeth that were pulled when he was neutered and then I have the ones that I found around the house that he lost too. And just an fyi... I thought he would be finished losing his teeth too by about 8 months bc thats when I had him neutered, but at 10 months he was still losing his molars. So no worries that he's still teething at a later age!
