Our two are both very vocal but in very different ways. Crook tends to bark more. He also has the typical yelp (?) when he's sniffing. Bel, on the other hand, barks little but tends to yodel and howl more. She sounds soooo cool when we get home everyday. Arooooooooooooooooooooooooooooooo! Love it! She also coos and purrs at me while she lays on my chest. Peggy hates it Bel NEVER does it with her.
