Why do dogs wag their tails? The quick answer is that a dog wags its tail for a reason which seems self-evident enough, being that it’s the tell-tale mark of a friendly dog. Indeed, anyone who’s stood near the pounding tail of a prototypical friendly breed, such as a Labrador Retriever, can take a veritable shellacking from the whack of its wiggle. But if friendliness were an altogether accurate interpretation, why is it that so many people are bitten by a dog that’s wagging its tail, often very enthusiastically?
For this and other reasons, behavioral science has called into question the popular wisdom that dogs wag their tails out of friendliness. The definition that behavioral science prefers (and which an energy model finds wanting) is that a dog is wagging its tail as a submissive overture to a superior member of its pack. For example, if one observes an inferior wolf approaching a superior one, tail-wagging is a pronounced feature of his body language.
But this isn’t wholly satisfying either because when adult wolves regurgitate food to their cubs, the cubs’ tails are wagging and so are the adults’. Are the adults being submissive to the cubs and the cubs to the adults all at the same time? That seems like a confusing scrambling of signals and it’s my experience that the nature of behavior is never that ambiguous.
The recurring theme of this blog will be to make the point that submission and dominance, while expedient, convenient, and seemingly reasonable means of making sense of canine behavior, can’t really accommodate the data. For if a dog is showing submission to a human out of respect, why then would he bite such a person? Such paradoxes plainly call into question the traditional scientific interpretation.
A thinker on dogs who I respect quite a bit, (although once again lacks a model for what’s going on inside the dog’s mind), is Desmond Morris. For our current purposes I call on his book Dogwatching wherein he writes at length on the phenomenon of tail-wagging. He states: “The only emotional condition that all tail-waggers share is a state of conflict. This is true of almost all back-and-forth movements in animal communication. When an animal is in conflict it feels pulled in two different directions at the same time. It wants to advance and retreat simultaneously. Since each urge cancels the other out, the animal stays where it is, but in a state of conflict. Essentially the animal wants to stay and wants to go away. The urge to go away is simple–it is caused by fear. The urge to stay is more complex.”
I agree that tail wagging indicates a state of conflict, there is an inherent momentum pulling/pushing the dog forward, but something is causing it to hold back as well. A state of attraction in conflict with fear: this is why dogs wag their tails.
It also needs further elaboration, for example, if we consider a dog who we can be sure is never going to bite anyone but who nonetheless is wagging his tail, what possible fear might there be for this dog in a situation where it’s only about to be petted, or fed, or any other number of pleasurable experiences?
The full answer to that question will be covered in an upcoming article entitled, “The Nature Of Fear”. However, Desmond Morris’ assertion that the the urge to go away from the person or dog because of fear, is simple, is mistaken. Fear is a little more complex than he has presumed. But putting that dynamic aside for the moment, for now I would simply like to elaborate on Desmond Morris’ insight by going a step deeper into the phenomenon of the friendly dog wagging his tail.
Tail wagging is indeed a state of conflict. But the conflict is arising from the following condition: it is the state of the body vibrating with more energy than the body at that moment is able to conduct given whatever action is currently available to it. In other words, there is more energy trying to go through the pipe, the dog’s body, then the pipe can accomodate. Wagging the tail is the body’s physiological response for dissipating the excess energy. And while it would feel better to the dog if its body could process the energy in a straightforward active range of behaviors, for example by making hearty physical contact, but for a number of reasons which we’ll discuss when we consider the nature of fear, it can’t. Hence the state of conflict with the tail going a mile-a-minute beating out the energy just like the utility meter spinning at high speed on the side of a house .

Natural Dog Training is about how dogs see the world and what this means in regards to training. The first part of this book presents a new theory for the social behavior of canines, featuring the drive to hunt, not the pack instincts, as seminal to canine behavior. The second part reinterprets how dogs actually learn. The third section presents exercises and handling techniques to put this theory into practice with a puppy. The final section sets forth a training program with a special emphasis on coming when called.Tags: attraction, behavior, fear, tails, wag
I’m really enjoying your insights. Thanks for the fountain of information.
That makes good sense, especially in relation to my #2 dog, Duncan. He is definitely energized by people and his tendency is to make “hearty physical contact”. He likes to jump up on people and make face contact. He gets especially excited when my son comes for a visit. Duncan’s tail becomes a helicopter and the sound he makes is almost as if he’s crying; a mix of growling/whining and he always goes and grabs something to have in his mouth. He gets so excited in the presence of certain people that it looks very much like aggession only I’m not convinced that’s what it is. Is there an effective way to channel this energy so his greetings will be less physical?
It may be a judgment that being near isn’t quite enough because Duncan is vibrating with the noise and while the tail is supple, it is unwinding a mighty spring. To work on Duncan, find the equal/opposite area where he is doing the opposite. If he avoids something, work on this. Notice also how he is the perfect complement to your other dog described on your other post. It would be interesting to know if they play tug with all their might.
Okay, now I’m seriously considering being impressed with you! (wink, wink) That you made that observation re: Duncan and Diva. She’s my #3 and when I took the boys for a ‘”meet n’ greet” before I adopted her, that’s almost the exact comment the adoption counselor made about their interactions. And yes, I believe they do “play with all their might” when they play tug together. Duncan gets very vocal; sometimes it borders on sounding like he’s very angry or a mix of frutstrated/angry. She seems to have him all figured out and knows what to do with him. For example, Duncan has shown an escalating tendency for aggressive behavior towards Bodie (#1) and Diva will come in between and block Duncan from making contact with Bodie and then she proceeds to act very “preyful” to get Duncan (as I see it) to chase her and get rid of all the stress/tension. But I digress…I’m not sure I understand your suggestion for equal/opposite with Duncan. Would you provide some clarification? Thanks!
When Duncan is escalating the situation with Bodie, he is transmitting energy that he normally holds in, and Diva is attracted to this energy, she has no idea she’s protecting Bodie, which is why she becomes the opposite to Duncan in order to fit with him. This also means that there is an opposite place in Duncan wherein he internalizes the energy that he under certain circumstances externalize toward Duncan. For example, perhaps he is afraid of thunder and slinks away. This equal but opposite to externalizing and is therefore the input/loading mechanism that then sits around in his emotional battery until triggered. This is the real source of the “vibration” and this is the best place to affect change in the overall. If this input were to 100% soften, then there would be no output.
My brain is grinding away trying to digest this so that I can make practical application. Am I correct in thinking that it’s fear-based and so should look for situations wherein Duncan is afraid but shows no outward/physical behaviors, instead avoids by turning away or going in the opposited direction? Or could it be any situation that is energizing and yet he ignores or turns away?
Just a note regarding Duncan: I adopted him from an animal shelter when he was 4-months; he came in as a stray so I have no way of knowing whether his current behaviors are based on past experiences prior to my adopting him or if they are a result of my own ignorance/mishandling. At any rate, I don’t want to add any more to the pile and really want to get to that place with him where he is free to be his real doggie self. There are times when he feels very much like he’s still a puppy and I wonder if there is something ‘missing’ from his puppyhood that needs to be corrected or fulfilled.
Both those scenarios could be right because if there is energy on the table and we’re dealing with a young, active dog, and said dog doesn’t engage and participate in movement of energy, it is due to fear. The energy is being absorbed but the dog is internalizing and holding back. So what is the one thing about Duncan that is the most opposite to his episodes with Bodie?
Don’t worry about compensating for an earlier deficiency, in fact, that only builds on it. Duncan is computing energy perfectly, the point of the dog in our life is for us to learn how to read the input and the output.
So I was just out in the backyard with them and I had a soft, squeeky toy on a rope. Bodie usually runs around with the ball until I kick it for him. I had played a little tug with Diva and then was playing with Duncan. At one point, he growled at Diva as she was trying to grab the tug toy. A slight flush/tingle of fear went through me and that effected a significant change in Duncan. Prior to that Duncan and I had been running back and forth (my back yard is fenced) as Duncan held the toy and he wasn’t showing any interest in tugging. After the “incident” his whole demeanor changed and he would back away from me and turn slightly to the side if I approached as he kept a (seemingly) wary eye on the other two dogs. And he slowed down in his movements and would pull hard and steady on the tug watching me intently. When I offered him a treat to get him to drop it, he kept a tight grip on the toy. I ended the game and came inside as now I am uncertain and quite shaken by the experience. I’ve never been afraid that Duncan might bite me but I was at that point. Now what do I do?
I went back out with Duncan (3 years in November) sans the other 2 and did some push-of-war with him. Again, we ran around the yard with the tug toy and I had to encourage the tugging. He never did growl again, even though I would push and crowd him a little. When I let him “win”, he runs away with the toy. He does relinguish for a treat once and again for another squeeky toy. At that point I end the game, even though he still is very eager to get the toy again. Inside, he does seem to be defensive as he growls seriously at Diva when she approaches the crate he’s in. I do have to say regarding Duncan, that he’s very good at going to his crate (actually it’s Bodie’s crate; occassionaly Diva’s) on his own when he feels a little stressed. The other two prefer to be wherever I am and will lie down and wait until I move to another room. Duncan doesn’t follow me from room to room; unless of course there’s food involved! I like that he can be by himself.
This is getting somewhere. The crate is a place where Duncan is free to express his fear, meanwhile you are projecting some judgment about “can be by himself” as in a need to guard one’s personal space from intrusion and this overcompensation is the source of the fear he is expressing when over reacting to strangers and toward Bodie.
Huh. Perhaps a miscommunication on my part. I am, by nature, an out-going, gregarious creature and can be “hyper-friendly” and a bit over-the-top sometimes in my enthusiasm. At the same time, I require a generous amount of “down-time”. That being said, my intent was that I appreciate that facet of Duncan; that he is able to/comfortable in being in his own space. At the same time, I take it as a complement that Bodie and Diva like being in close-proximity. Whatever.
Hello, my words may sound childish, (because I am one, but I will not state my age, and yes I know I sound older than I really am) I am looking for the responces to Dogs in everyday life, here are some examples.
What do dogs do when they are cold?
What do they do when they smell something bad?
What do they do when they get hurt?
Simples questions like those would help me in sience. So please answer them! Thank you! Bye. =)
It depends on the size of the dog, and the breed on what they do when it is cold. I have one (a Australian Cattle Dog) that jumps and seems to rejoice in the snow, but also a Min Pin that HATES the cold and hides as much as she can. My cattle dog raises his head and looks like he is VERY interested in smells, the min pin searches the smells out. Both love the snow, and hate the cold.
