Never heard of them. This was suggested in the sidebar of YouTube site, unconnected subject-wise to what I was watching, a whole series of videos of Russian soldiers dancing. The dogs aren't really dancing. This woman and her dog won in this free-style competition. I'm showing this because YouTube sure does know what I like. Commenters to the video liked this more than I did. The whole time I was thinking, "Boy, that sure is a sweet little fluffy Belgian Malinois.
Fake! That grenade didn't even explode.
The woman who won in the heeling category also won the whole competition. I think. I don't know. I'm going by comments to the two videos. Commenters wanted the free-style one to win. They like the first video better than this one.
I'm struck that the winner is another Belgian sheepdog, Tervuren this time. They're the same dog structurally while their coats vary dramatically. If you choose to watch, you'll notice the dog doesn't so much heel as it herds. In real obedience the dog would be marked down for crowding. The dog shoves with its shoulder, it leans way into its handler in both directions when exaggerated. The dog moves between the handler's legs in figure 8, and it switches sides from left to right of the handler. In its way, it dances. But it doesn't tell a story like the free-style video does so commenters liked it less.
The first woman is from Italy. This woman, below, is from Russia. Their routine is to Édith Piaf. If you stick with it you'll see the dog really does herd the woman this way and that, sideways, forward and backward. Like a dance.
