Sabrina is definitely a yapper, she has a high pitched almost scream, she howls also like a little wolf, but she has to be really excited about something to do that like when she see's another dog besides Blaine, or the little chihuahua from next door comes outside, or starts barking. Blaine on the other hand barks and makes this growling, crying type noise, I've never heard a dog make that sound before, I'll have to record it and post a link to it so that you guys can hear it, it's crazy almost like he's talking to me. But I definitely got one loud yapper, and deep barker.
