For example, a dog exhibiting the scratch reflex is an example of knismesis. When stimulated in the saddle region, most dogs will exhibit a reflexive rhythmic twitching of their hind legs. This reflex can be brought on by actions such as scratching, brushing, stroking, or even tapping the sensitive area.
Once stimulation of this area begins, the dog will begin to rhythmically "twitch" or "kick" their hind legs in an attempt to rid itself of the "irritant". Typically, only one of the hind legs will exhibit this reflex at a given time, however, it is possible for both legs to undergo the reflex at the same time.
