The methods and tools of the behaviourist will depend on several factors including the dog's temperament, the behaviourist's personal philosophy on training, the behaviourist's experience, and the behavioural problems being addressed. At one end of the spectrum, some behaviourists attempt to train dogs, refraining from the use of aversive or coercive methods (and the tools associated with them, such as choke, prong/pinch or electric shock collars, kicking, hitting, poking, staring, shaking, or rolling), choosing instead to rely on reward-based methods. Dog behaviourists and dog trainers with a knowledge of how to approach training in a behavioural way usually do not offer guaranteed results.
