In Defence of Dogs: Why Dogs Need Our Understanding by John Bradshaw is aimed at the general reader, giving an overview of both the development of dogs as a species and their ethology. The author's credentials are excellent; he is a biologist who founded the anthrozoology department at Bristol University, and his studies into canine behaviour are causing ripples throughout both the scientific and the popular dog world. Increasingly, the idea that we have to somehow get the upper hand and dominate the dogs we have as companions or working dogs is coming to be thought of as wrong thinking. According to Bradshaw, "Dogs don't want to control people, they want to control their own lives."
Before investigating dog behaviour however, Bradshaw delves deeply into dog origins - their evolutionary journey and their relationship with ancestral wolves. For about a century we have assumed that dogs are merely "tame wolves", and even in recent decades we have sought to justify this scientifically because 99.96% of their DNA is the same as the grey wolf. However Bradshaw catalogues the DNA of many types of wolves, foxes, jackals and wild dogs from prehistory to more recent times, and comes up with some surprising conclusions. The timber wolf, whom we all tend to assume is our dogs' remotest ancestor is unlikely to be so, since its territory became more and more restricted (due to human intervention) and the genetic material in modern dogs looks much more similar to a little foxy/jackal-type creature living many years ago in North Africa, not America.
These first three chapters about the genetic inheritance of dogs do tend to drag a little. Bradshaw is so keen to properly document his findings, referring to numerous studies which have been done, that he is in danger of forgetting that his audience is not academic scientists but the general public. He often seems to be writing a book for other biologists as part of an ongoing study. Nevertheless the material is fascinating, covering not only the differing genus of wolves/dogs but also the tribes of people world-wide and their relationships with them. Dogs were pictured in prehistoric cave-paintings for example, showing their value and importance to the peoples of the time.
The middle chapters concentrate on the physical attributes of dogs; their brainpower, emotional states and sensory capacities. We tend to think of dogs as similar to children; to assume that their behaviour is essentially similar to our own. Bradshaw demonstrates that this is doing a dog a great disservice. Because of the way a dog's brain is constructed it has differing abilities from us, and thinks in a different way. It is not "lesser" but "different". Similarly, the emotional experiences and sensory capabilities are different. The most obvious difference in their capabilities is their sense of smell, which for physical and mental reasons is profoundly superior to ours - somewhere between 10,000 to 100,000 better in fact. We have 6 million olfactory receptors in our noses, but dogs have 300 million. And the area of a dog's brain devoted to analysing smells is 40 times greater than ours. They even have a special organ which we do not have - a "Jacobson's organ" somewhere at the back of the palate - to help them identify and catalogue odours even more precisely. At this point the reader begins to wonder what we are subjecting our dogs' sensitive noses to with our fake "clean" household detergents, air fresheners and so on.
Clearly dogs are able to detect infinitesimal traces of scents compared with us, just as they are able to hear well outside our auditory range. These senses are both much more highly developed than humans'. Yet their vision is not as precise. They have different colour receptors, which mean that they can easily distinguish between red, blue and green, but find yellow/orange/red differentiation slightly tricky. Night vision is easy for them, but they do not see as well as we do in bright light.
Yet knowing all this we do not properly take it into account when assessing dogs' behaviour. We continue to criticise dogs for not sensing the world the way we do, and castigating them for behaving differently. Their brains clearly work differently from ours in a multitude of ways in addition to the simple sensory organs described. Tests have indicated this over and over again.
Here is an example of a basic mistake in understanding and being realistic in terms of dog behaviour. We insist that we want our pets to be loyal and attentive, but also to "understand" if they are left for hours on end. A dog may well try to occupy itself during this time by shredding something. The common perception is that it "looks guilty" when its owner comes back. (We all do this - even dog behaviourists have been caught out!) But how can it? The dog makes no connection between the shredding and the return; its brain simply does not work that way. This is just our habit of slipping into anthropomorphism.
What the dog is doing is simple reinforced behaviour. The dog thinks, "Sometimes when my owner comes back I get told off. Sometimes I get praised. I don't know which this will be," and proceeds to stay low and do affiliation or appeasement behaviour until the situation becomes a bit clearer. The dog learns quite quickly how to handle us - or teach us how to behave! What often goes wrong in such a situation is that the owner gets increasingly angry at the shredding on each return, thereby setting a pattern and making the dog increasingly anxious. The same thing happens on daily walks. How often do you see a dog returning to its owner, only to be chastised for taking too long. Where is the motivation to return then?
These middle chapters document many studies into dog behaviour, based on the earlier methods of work by Konrad Lorenz. For instance his theories on imprinting, feedback mechanisms, adaptations - in fact all his behavioural research was based on observation. Bradshaw uses similar studies - sometimes but by no means all devised by himself - to demonstrate how a dog's brain works. There is one experiment which is very similar to Thorndike's boxes, which carefully analyses the thought processes a dog will go through in order to obtain food, when it is hidden in various places. Including an owner in such experiments makes even more deductions possible, especially an owner who deliberately lies, or an owner who has been misled about the truth. A mine of information can be gleaned from such an experiment when correctly performed and recorded. From here the reader can move to drawing conclusions about dogs' behaviour when interacting with humans.
The last two chapters go into the problems which come with breeding for looks rather than temperament. Humans have interfered in the genetics of dogs more than any other animal. Such is the gene pool of some particular breeds now, that all the existing dogs descend from just 6 males. Even with most dogs any mating within the breed at all is equivalent to humans marrying their first cousin. There are numerous instances of illnesses and conditions endemic to a particular breed, solely caused by human intervention. And the situation is escalating and getting worse all the time. Responsible breeders are recognising that something must change. Even as recently as a century ago breeds were crossed for strength, but large-scale concerns have done a lot of damage by line-breeding to produce a certain cosmetic "look." Bradshaw also advocates small breeders for behavioural reasons too. They will give the time and care needed for puppy socialisation. The first 7 or so weeks in a puppy's life are crucial in order to develop healthy behaviour.
Bradshaw is also critical of the plethora of different regimes and "societies" that have sprung up in recent years devoted to helping us to turn our companions into the sort of dogs we want them to be. They are for the most devoted to reinforcing "good behaviour" encouraging partnership and cooperation between owner and dog, which he feels is laudable. Only a few remain which are endorsing outmoded theories about dominance. However the list even in the UK is a very long one, so that a new dog-owner would be hard put to select an appropriate organisation to go to for advice.
John Bradshaw tries to cover a lot of ground in this book; possibly too much ground. It could easily have been converted to two books - or even three. That way more anecdotal information could have been included, to increase the flow; unfortunately it is frequently not an easy read. Some parts could be edited, whereas others are interesting in themselves but presented in a dry academic style rather than a readable one. However it is well worth sticking with as the information is not easily available elsewhere, and Bradshaw makes many good points.
