Allan goes everywhere with Birgitta Anderson, a 54-year-old secretary. He moves around her office at work and goes shopping with her. ‘Most people don't seem to mind Allan,’ says Birgitta, who thinks he is wonderful. 'He's my fourth child,' she says. She may think of him and treat him that way, buying his food, paying his health bills and his taxes, but in fact Allan is a dog. Birgitta and Allan live in Sweden, a country where everyone is expected to lead an orderly life according to rules laid down by the government, which also provides （提供）a high level of care for its people. This level of care costs money. People in Sweden pay taxes on everything, so aren't surprised to find that owning a dog means yet more taxes. Some people are paying as much as 500 Swedish kronor in taxes a year for the right to keep their dog, money that is spent by the government on dog hospitals and sometimes medical treatment for a dog that falls ill. However, most such treatment is expensive, so owners often decide to pay health and even life insurance （保险）for their dog. In Sweden dog owners must pay for any damage （损坏）their dog does. A Swedish Kennel Club official explains what this means: if your dog runs out on the road and gets hit by a passing car you, as the owner, have to pay for any damage done to the car, even if your dog has been killed in the accident.
