Ever since Mahina got her "adult teeth" in I've consistently brushed every single night (okay, i've missed maybe 3 nights in the past 6 months).
I use this Four Paws vanilla mint doggie toothpaste every night.
I use Petzlife gel twice a week.
She chews on bully sticks, nylabones and white bones.
No wet food, only kibble that get's topped with salmon oil and glucosamine.
Now... WHY does she have tartar on her molars?!

Am I doing something wrong, I really make sure to brush every tooth well since she's grown to tolerate it
She'll be 1 yr in July.
Can I use those metal dental scrapers on her... or do something different?
A different toothpaste?
Help!
