Have you ever had a dog this vocal?
Oh yes! My boy Sunny would vocalize on cue, and even if you picked him up he would continue until he was done. I have video somewhere of him howling while being held upside down.
We were driving by a nicely fenced off-leash park on Nimitz Dr. this past Monday afternoon and were pleasantly surprised to see a lovely red & white Basenji playing with the others! Our girl came home from her former walker's place this afternoon and was quite happy to see everything (and everyone) was in its proper place.
