I'd have to get pics and I'm not sure you could tell much because you can feel the fluid in the hock joint bend, not really see it much. If you can imagine a bent leg, right in the bend, on the back of the hock joint is full of fluid; also higher up, there is a raised bump and on the outside of the hock, there is a lump of fluid or infection that is a bit below the actual bend. Before, it was always localized in one spot we could lance open, but now it's more scattered.
