I found something on the floor last night. It was smooth, hard, a tad brittle, and almost looked like a bone splinter, but we don't feed RMB. After some more examination, the only explanation I could come up with is that it was a tooth fragment.
After 3 hours of searching Zander's mouth, giving him cookies, searching for pain, swelling, or heat...I gave up. He doesn't appear to be in pain, he'll eat just fine. He's playful and happy and there's no swelling or heat that I can find. If it is a tooth fragment, it must have been the very outside of the enamel, and no where near the core...or else I would assume he would be in so much pain. And I can't find any cracked surface on his teeth anyway.
And he's such a huge baby, I doubt he would be hiding any pain at all. He's milking his hips right now as I type this.
I'll call the vet Monday. He's going to need an international chip and rabies vaccination anyway, might as well get it out of the way and have someone else search his mouth.
But the last thing I want is this old man going under for dental work.
