Dogs are not like nicely brought-up wolves, says the author, nor are they much like people despite their extraordinary ability to enter our lives and our hearts. This is not to deny that some dogs are very clever or that they are capable of feeling emotion deeply. But their intelligence is different from ours. The idea that some dogs can understand as many words as a two-year-old child is simply wrong and an inapproprhate way of trying to measure canine intellect. Rather, their emotional range is more limited than ours, partly because, with little sense of time, they are trapped almost entirely in the present. Dogs can experience joy, anxiety and anger. But emotions that demand a capacity for self-reflection, such as guilt or jealousy, are almost certainly beyond them, contrary to the convictions of many dog owners.
Mr Bradshaw believes that it is difficult for people to empathise with the way in which dogs experience and respond to the world through their extraordinary sense of smell： their sensitivity to odours is between 10,000 and 100,000 times greater than ours. A newly painted room might be torture for a dog； on the other hand, their olfactory ability and their trainability allow dogs to perform almost unimaginable feats, such as smelling the early stages of a cancer long before a normal medical diagnosis would detect it.
The latest scientific research can help dogs and their owners have happier, healthier relationships by encouraging people to understand dogs better. But Mr Bradshaw is also fearful. In particular, he deplores the incestuous narrowing of the gene pool that modern pedigree breeders have brought about. Dogs today are rarely bred for their working abilities (herding, hunting, guarding), but for a very particular type of appearance, which inevitably risks the spread of physical and temperamental abnormalities. Instead, he suggests that dogs be bred for the ideal behavioural traits associated with the role they will actually play. He also worries that the increasing urbanisation of society and the pressures on couples to work long hours are putting dogs under huge strain. He estimates that about 20% of Britain's 8m dogs and America's 70m suffer from ゛separation distress゛ when their owners leave the house, but argues that sensible training can teach them how to cope.
゛Dog Sense゛ is neither a manual nor a sentimental account of the joys of dog-ownership. At times its rigorously research-led approach can be slightly heavy going. A few more jolly anecdotes might have leavened the mix. But this is a wonderfully informative, quietly passionate book that will benefit every dog whose owner reads it.
