Having trained both, I would have to say that our breed takes to it better than to standard obedience, although it is not as instinctive a behavior as herding.
Agility requires that the dog learn to negotiate particular obstacles.
Some, like bar, panel and broad jumps, are relatively easy. Others, such as the tunnels and chutes, require sufficient confidence to leap into a dark hole and know Mom will be waiting on the other side. The Dog Walk and Teeter Totter require a sense of balance, and a knowledge of the position of each foot. The tire jump and weave poles need a willingness to please, while the pause table tests the dog's willingness to accept control. Introducing the obstacles carefully and positively allows most Samoyeds quickly develop the confidence that marks a good agility dog.
