B
We went to an animal shelter to adopt a puppy, but in reality, it was the puppy who adopted us. As we looked into the cage, a small, three-month-old beagle(小猎兔狗) puppy began wagging her tail. She seemed to say, “Oh, you’re the family I’ve been looking for!” And for the next fifteen years, Pudding (we named her Pudding because she was as sweet as a pudding dessert) became part of our family.
Pets are always popular in Western countries. Now, China is also discovering its love for cats and dogs. The pet industry, which sells food and toys as well as grooming (刷洗梳毛) and vet services, is one of the country's fastest-growing industries.
Pets bring a lot of joy to your home, but they are also a big duty. Pets are not toys. You cannot put them away when you are tired of them. Dogs, in particular, need to be trained to behave properly and they need exercise. Even in bad weather, you have to take them for walks or for a run in the park. While you are training your dog, your dog is also training you to think about others and care about others, not just about yourself.
Pudding was my best friend when I was growing up. We sat together on the sofa and watched television. She kept me company when I was doing my homework. And when I came home, she was always there to greet me, leaping up and barking and wagging her tail.
Pudding is now gone, but you can still recognize her in old family photos: she is the one wearing fur.
