I don't see them often. They vary. Show bred. Field bred. They need to flat out run for a long time, more marathoners vs sprinters. They are meant to be moving, running, flushing, looking, sniffing, etc. Busy! I think they can be difficult when they are younger, like Labs can be. I see more GSPs in the ring than Viszlas. I never really see pointers in agility. Their structure is not really made for it. I like them, but not sure I'd personally get one without property or time to really run them on a daily basis. They are bred to be far from their handlers looking for birds to flush. They can be nervous dogs. You'll have to look up their breeds standings in the different sports, see how many there are and how well they do. I'd be curious to see what you find out.
