This is a dog raised by Kevin Costner (yeah, I know, you don't believe it, but it's the so-called Truth) and he (the dog, not Costner) is howling because he's longing to DANCE with the wolfs. This also means the dog is a relative to our great song-and-dance man haiducii, and his (the dog, not haiducii) real message is: -C'mon pal let's hit the disco dance floor!
That's what the dog is saying...
