When he first sees me come home, Ozzie is like AR AR AR AR and "RAH, RAH RAH RAH" kind of like a cheerleader and jumping around just as much.
If it's past time to eat, if he's ready to go to bed, or is desperate to get your attention it's more BRUH, BRUH, BRUH.
His "affirmative/yes" bark is RUH, RUH RUH. And sometimes he actually SAYS no! Probably more like a Scooby or Astro .... ROOOOOOOOOOHHHHHHHH. It's hilarious.
