I found quite a bit of Marley's believe it or not. I had more but silly hubby threw them away at the time thinking that is why I had them on the table. SILLY MAN! Anyway, I was able to get a few more, think I have 8 to 10. I got lucky in that he played in the den all the time and that's where they'd drop. Also found one in his crate.
A couple of times he would shake his head real hard like he was trying to get something off him, and I'd see the tooth hanging, once it fell I was on it, ahahhahah.
Silly mommy
