The Amazing and Astounding SINGING and DANCING Labrador RETRIEVER!!!
Day 2 with winger - YouTube
I think that the tappy toes and singing is baked into the cake at this point, though it seems to be getting incrementally better... very, very incrementally better... as time goes on and we work on this 2-3 times/day*. She jumps forward a little bit, but is then jumping back on her own accord as she does her little jitter-bug jive thing.
*When I say 2-3 times/day, I'm talking very short sessions and I've never seen her get down or act bored. Hello? This dog bored? Uh, not likely!
