In a fit, lean horse the jumper's bump region may appear unusually prominent, but this is just normal anatomy not masked by excessive fat. It doesn't mean that the horse has a problem.
The above is taken from an article in H&H. My horse has a very prominent jumper's bump, so I'd previously done a bit of research on it and came up with this.
That's good to know I've heard so many different things about this subject - my horse too has a prominent jumpers bump - my vet told me once that it's not something they fail a horse on in a vetting
A jumpers rump used to mean that a horse with a prominent one would usually have a big jump! Vets cant fail them for having one its just something some horses have without it causing any mechanical problem.
Can mean weak Sacroiliac area apparently, a physio I know said horses with large jumpers bumps can be prone to weakness in the area. Mine has a jumpers bump!!
