in my very humble opinion..the toughest dog behavior is anxiety. causes all sorts of stuff. biting, fighting, destruction...

a calm-ass dog is the best thing ever. with my wife's mission to never buy, but adopt..I will have anxious dogs damn near forever, I bet. some level of anxiety. they dont come out of loud, dog shelters unscathed in my experience.

hence the break after Hank. maybe someone surrenders a labra-doodle..hahahha..
