Hunting and working dogs were typically of the standard variety, though some reports suggest that smaller varieties such as the miniature may have been popular for truffle hunting, as their feet were less likely to damage the delicate fungi. Miniature and Toy varieties tend to be bred primarily for companionship. The outcome is a gun dog with extreme intelligence, a relentless drive to catch its quarry, and strong swimming skills that require special training: their aptitude is second only to the British Border Collie and thus the hunting Standard Poodle requires the gunman to be quite specific as to what he wants and how he wants it done and to avoid becoming too repetitive doing training drills so the dog does not become bored: it likes to be challenged.
