Many people says that dogs are the best friend for human. In the reality, many dogs are more selfish. Dogs prefer to play with their toys than to help human or they do not understand the request from human. To find out about this thing, Piotti and Juliane Kaminski doing a research with 24 samples in the lab. Researchers test the dog one by one by putting a toy in one corner of the room and hiding a notebook which dog also see of another person using it also they put staplers. As the result, dog play often with their toy than the notebook then staplers. According to Clive Wynne selfish behaviour of dogs is not surprising actually. They are interested in an object that they like. Different opinion from Krista Macpherson, she said "Does the dog take an interest in an object that a human is interested in, or only in objects that dogs are interested in?The question is, how much understanding do the dogs have of these helpful behaviours?". Dogs are brilliant animals which can read human clues but without direction it will be difficult thing to do.
