How do you keep cattle work from making a horse hot?

A horse getting progressively hotter through its cattle work is one of the most common training deteriorations in rope horses, and it develops gradually enough that many ropers do not recognize it until the horse's behavior has changed significantly from where it started. The pattern is consistent: cattle work always involves speed, chase, and high adrenaline, the horse begins to associate cattle presence with that arousal state, and eventually the arousal begins earlier in the sequence — in the warm-up, at the gate, in the box — as the horse anticipates what cattle time always means. Prevention requires that cattle work not always mean the same thing. Vary the session deliberately: sometimes walk to the cattle pen and stand quietly without making a run, sometimes lope around the cattle at a distance without chasing, sometimes work cattle at slow pace with frequent stops and standing rest beside the cattle. The horse that experiences cattle work as sometimes slow, sometimes fast, sometimes stationary learns that its arousal level should be determined by what is actually happening rather than by the presence of cattle in general. Keep the ratio of low-intensity cattle exposure to high-intensity runs higher than feels productive — if the horse is currently hot, that ratio may need to be heavily weighted toward slow and quiet for several weeks before intensity is reintroduced. Horses that are consistently brought back to calm beside cattle before a run is made, and consistently cooled down beside cattle at the end of a session rather than taken away from cattle while still hot, develop a much more regulated relationship with cattle over time than horses whose cattle sessions are uniformly high-energy from start to finish.
