Of all of our collective pugs (including the 3 pug cousins), Cleo has by far and away the best dental health. I would love to pat myself approvingly on the back, but it really has nothing to do with me -- she's lucky if she's in the same room with her toothbrush more than once every few months.
I do every once in a while get out the dental pick and go to town on her tartar.... except that she doesn't have any. Just a smidge, maybe, on her gravestone front teeth, but that's about it. We have a few theories. One, that she's a genetic mutant with super-resistant dental genes.
Two, that her hyperimmune state, the one that is the source of all of her allergies, is actually protective against gingivitis.
Or, three, that her ridiculously obsessive chewing is scraping those gigantor teeth clean without anyone's help.
