Agility or Flyball harder on joints?

[Caro]

I'm not an expert on either sport (especially flyball!) but I think that when done INCORRECTLY, or not properly trained, that flyball seems to be worse.

In other words, a poorly trained flyball dog is at higher risk than say a poorly trained agility dog. I see a lot more incorrect (and thus unsafe) flyball turns than specific agility maneuvers.

Likely when taught correctly it's a different story.

I think you're right there. My dogs' physio thinks flyball should introduce a system like agility contacts - where an incorrect turn on the box is considered a foul. It may not matter as much with very slow dogs but there is still an attitude that box turns don't matter for small dogs. Most of the top teams here don't have that attitude but unfortunately for Tully it is one that prevails in my own club. With flyball becoming faster and faster I think it's time the officials took a closer look at the turns and boxes were designed with biomechanic specialists.
