I can't believe it! He's gone from a little "worl worl" to a mini growl, but now he's outside in 40 degree weather cussin' me out! I'm so proud.
Of course, he never has a reason to bark and naturally chooses not to, but, well . . . I put him in the back yard while I checked my email and he is soooooooo not having it.
And he sounds like a grown up doggy too! I'm so excited.
