Yup - that's why I thought it would help @BGpa if he could do that, I think it would make it easier to see it in horses. I use to watch videos of musical dressage at highest levels and they would choreograph the movements to music. The trotting, extended trotting, canter and changing leads all perfectly timed to the music. One day a song came on the radio and I was skipping around to the tune like a cantering horse doing flying lead changes. Yes, I was home alone.
I was watching slo mo race horse strides and slo mo greyhounds - I'll have to put them up here. But back to the shoulder angles - QH might need more layback for cattle work and barrel racing - lower center of gravity and more control in tight turns, where as other breeds may not need or benefit as much. I never studied canine athleticism like I did equine, but I'll bet watching agility one might start picking apart what is working for agile dogs in different breeds. Horses aren't extremely different from each other but dogs are all over the board in shape and size!
I think dogs mostly cross-gallop? It's crazy making to those of us use to horse footfall patterns.
