I have a labradoodle now 9 months that still mouths alot. As many times as I have corrected her for this she still insists on doing it. I've tried giving her something else to do by saying "kisses" which to her means licking and she does it right away but I get as much mouthing as I do licks. It is gentle mouthing but it is still mouthing. Do they outgrow this? How concerned should I be about this?
