　　The dog that gave us the most trouble was a beagle (猎兔犬) named Murphy. As far as I'm concerned, the first thing he did wrong was to turn into a beagle. I had seen him running and jumping around on the other side of a pet-shop window, and I went in and asked the man, "How much is that lovable fox terrier (小猎狗) in the window?" Did he say "That lovable fox terrier is a beagle"? No, he said, "Ten dollars, lady." Now, I don't mean to say one word against beagles. They have rights just like other people. But it is a bit of a shock when you bring home a small ball of fluff in a shoebox, and three weeks later it's as long as the sofa.

　　Murphy was the first dog I ever trained personally, and I was delighted at the enthusiasm with which he took to the newspaper. It was some time later that we discovered, to our horror, that-like so many dogs-he had grasped the letter but not the spirit of the thing. Until the very end of his days he felt a real sense of duty whenever he saw a newspaper-any newspaper-and it didn't matter where it was. I can't bring myself to go into the details, except to mention that we were finally forced to keep all the papers in the bottom of the icebox.

　　He had another habit that used to leave us open to a certain amount of criticism from our friends. He never climbed up on beds or chairs or sofas. But he always sat on top of the piano. In the beginning we used to try to pull him off. But after a few noisy fights in which he knocked a picture off the wall, kicked the piano, and broke a lamp, we just gave in-only to discover that he hopped up and down as skillfully as a ballet dancer.

　　Nowadays if I go anywhere, I just ask if they have a dog. If they do, I say, "Maybe I'd better keep away from it-I have bad allergy." This sometimes annoys the host. But it works. It really works.
