So about 2 months ago, Cooper started barking to alert us. He started barking at the neighbors grill and he barks at the people in their own yard and won't shut up. Its sort of a how/bark, high pitched and he "points" and his tail goes up. I'm hoping its a fear stage and he'll grow out of it. I just printed something off on the printer and he heard it start and started growling, I told him no and then he flew off the couch barking in that direction. He will even bark if he's in the car with us and we pass someone walking or another dog. Its embarrassing and loud! please tell me he'll grow out of this. He does it mostly in places he thinks are "his".
