Canine twist behavior — the puppy twists as a pacifying response to the adult’s growling (illustration by Alice Rasmussen from “Dog Language” by Roger Abrantes)
The canine twist behavior is an interesting behavior that few dog owners recognize, let alone know what it means.
It is a characteristic behavior shown by any canine, (wolf, dog, African wild dog and dingo at least) when it twists one hind leg out to the side. Most frequently, the dog shows it from a sitting position, but it can also do it from a standing position. In cases where the dog appears very insecure, the twist can be succeeded by a half roll culminating with the dog lying on its back and showing its belly. The twist is accompanied by laid-back ears, semi-closed eyes, champing (at times with the tongue protruding out of the mouth) and paw lifting (or vacuum pawing) in various degrees depending on the situation and the level of insecurity. It’s a fairly common behavior mostly seen in puppies and youngsters, but insecure adults can also display it.
The function of the twist is to pacify an opponent. As always, behavior happens by chance (or reflex), and if it (the phenotype) proves to have a beneficial function, it will tend to spread in the population being transmitted from one generation to the next (via its genotype).
The origin of the twist is most certainly related to the typical canine maternal behaviorof the female overturning her puppy by pressing her nose against its groin, forcing one of the puppy’s hind legs to the side. The puppy will then fall on its back and the mother will lick its belly and genital area facilitating the puppy’s urination and defecation. To start with, this appears to be a rather unpleasant experience for the puppy but becomes pleasurable once it is overturned and its mother’s licking achieves its function.
Later on, the puppy will perform the same twist movement in the absence of any physical contact with the mother or any other adult. It will do it when it feels threatened or insecure and with the function to pacify both itself and its opponent, rather than inviting to belly licking.
The transition from urination/defecation to pacifying is a classic of the development of behavior. It happens almost exclusively by means of a classic conditioning process. In the beginning, being overturned is unpleasant but lying on its back, belly up, becomes pleasant (due to the puppy relieving itself). After a number of repetitions, the puppy will associate lying on its back with ending discomfort and will readily display this behavior whenever necessary.
The strength of the twist behavior (a general characteristic of pacifying behavior) is its double effect of pacifying both parties. The puppy relaxes by doing something which has produced good results earlier. The threatening adult relaxes by being met with a behavior that it recognizes as infantile behavior.
I first described this behavior in the original edition of my book “Dog Language” in 1987. The behavior had no name at the time. I coined it the twist behavior thinking of the famous dance of the sixties, very popular in my teen years. “Twist and shout” by The Beatles* immortalized it. The Twist, the dance, featured a characteristic step, where the dancer’s legs made a twisting movement reminiscent of the puppy’s pacifying behavior.
Let’s twist again, my friends!
* “Twist and Shout” was written by Phil Medley and Bert Russell and first released in 1961 featuring the Top Notes. However, it achieved its fame first when The Beatles performed it in 1963 with John Lennon in the lead vocals.
