Get your minds out of the gutter
Do you do regular oral care on your dogs, and if the answer is "yes" do you include descaling tartar?
Do you brush "regularly" and how often is regular? (1x week? 1x day? 1x mo.?)
I'm just curious. I've started all our adopted dogs off young, or as soon as we got them, but Copper absolutely hates having his teeth done.
