Question about cutting horses

How common is it to see breeds besides quarter horse in competition?

IMO most QH, or stock type horses at better built for it. They have always for years and years been the "ranch" type horse, cutting a cow is more of a ranch thing. They have then mind, breeding and agility for it. Of course all QHs don't.

They are known to be smart, small, and quick which help.

Its not that other breeds can't, but it seems the QH is more geared toward that type of thing. At least they used to be.

At an open event you will commonly see Apps, paints and Arabs.

I have seen a bunch of really great cutting Arabs.

I can't really think of others I have seen besides the ones mentioned (Arab,App, QH/Stock)

I guess it depends on the horse though, these are just more common. TBs aren't exactly built to cut cattle, but maybe some do

Specifically, I was wondering about international breeds that have been used historically around cattle. Some of the Iberian breeds come to mind, like Lusitanos. Or Chilean horses as an example from the south.

I haven't seen any...

Australian Stock Horses are sometimes used for cutting over here.

Yup, that's another one I was thinking of

They are quite good at it. Cadabra, an ASH stallion, is being exported to Canada soon, and he will be put in reining/cutting training. Our 'camp' section of a campdraft is quite similar to cutting, though much shorter and less intense.

Wow, I just looked him up. Good looking guy!
