If you have a dog，you probably feel a strong bond（纽带） with it.A recent study found that this bond might be important to dogs，too.
Researchers at Oregon State University looked at the relationship between kids and dogs.They asked 30 kids（aged from 8 to 17）who have dogs to join the research.
The kids brought their dogs to a big and empty room.Each kid was asked to walk around the room，sometimes pausing （停顿） or changing direction."And the dog was left to do whatever it wanted.It could run around the room，or sniff，or lie down or sleep."says Monique Udell，one of the researchers.
But then they found that most of the time，the dogs didn't do my of there things.Instead，they stayed close to their young owners and do the same things that they were doing.When the kid walked，the dog usually walked，too.When the kid stopped，the dog stopped.When the kid turned and changed direction，so did the dog.
What does this mean？Udell says it's a dog's way of building a relationship with a human.The dogs did this with the kids，even though the kid's parents are usually the ones who feed and care for them."The kid may play a brother or sister role in the life of the dog，" Udell says.This shows ____ .
So far，Udell's team has only worked on dogs.But they would like to do similar studies with cats and other kinds of pets.Udell thinks that the animal human bond﹣eprond to them as well.
