|Not a happy camper.|
Although she's a tiny Airedale, barely 43 lbs, I can't brush her teeth. Just trying to look into her mouth involves a wrestling match requiring two hands, with none left over for the brushing. Miro is the opposite. I've been brushing his teeth several times a week since he was a pup and he enjoys the process, even if he doesn't exactly sit still. Do you know how strong an Airedale's tongue is when you're trying to get the brush up against his teeth while he's trying to lick off all the toothpaste?
I have seen dogs sit passively while getting their teeth brushed. Passive and still, however, are not in the Airedale's vocabulary.
