I love the dog!
We watched it on television some years ago, at recommendation of brother in law, and enjoyed it.
I put it on my Amazon wishlist last November, and said brother in law bought it for me for Xmas. Though it did confuse him, as the DVD was under the American title of "The Triplets of Belleville".
Watched it again, my husband didn't remember it at all and really enjoyed it all over again. As did I, having remembered only the basic plot ish, and the dog!
