A neighbor that has since moved had 2 toy Poodles. There was nothing they didn’t bark at. UPS, mailman, garbage trucks, you name it, they barked. I never understood it. If Poodles are so smart, can’t they figure out the mail man comes every day and isn’t a stanger? That garbage and yard trash is collected 3 times a week...every week? yap yap yap yap yap. Our dogs got so used to their yapping at things they shouldn’t yap at that they didn’t even bark when they began to yap at stupid things.
It didn’t really bother me much, more comical. Nice Poodles and their owners are close friends who now moved back up north. Miss them, not the yappers.
I think many dog owners just tune out the barking. When I'm fed up with my Poobear, SHUT UP works too. He retreats to his bed always with his ears tuned in for the next delivery truck. I really think these little guys just get bored. A good long walk and they quiet down nicely.
Gotta love ‘em!
