Guess what? Your dog can get jealous when you pay attention to other dogs, other people or even other things.

Dogs have complex   36   such as jealousy (嫉妒) and pride, according to a scientific research that throws new   37   on their relations with   38  .

Animal psychologists previously believed most animals lacked "  39   of self", which is needed to experience secondary emotions such as   40  , embarrassment or guilt. These emotions are more   41   than instant reactions such as anger or joy.

Professor Friederike Range, from the University of Vienna, has shown that dogs are jealous when they feel unfairly treated  42   to other dogs. "Dogs show a strong   43  to inequity (不公平)," she said. "If one dog gets something, you'd better believe another will   44   something as well."

But, her study   45  , it doesn't matter if one gets a better treat, only that the distribution is   46  .

The dog study is the latest into several   47  , including cows, horses, cats and sheep, which have   48   that animals are far more self-aware than   49   were thought.

Paul Morris, a psychologist at the University of Portsmouth who studies animal emotions, told The Sunday Times: "We are learning that dogs, horses, and perhaps many other species are far more   50   complex than we ever realized. They can   51   simple forms of many emotions we once thought only primates (灵长类) could experience."

In research among   52  , Morris found almost all of them reported   53   behavior by their pets. The dog often tried to get their owner away from a new lover in the early days of a relationship.

Behavior experts recommend owners keeping their dog's   54   as much as possible from a new partner or child . This helps to   55   jealous activity from the dog such as interruptions with barking or whining  (哀嚎).
