California Science Show Explores the Dog-Human Friendship

Did people decide to fall in love with dogs or did dogs choose people? And why do these two species1 seem to think so much alike, act so much alike and get along so well?

The California Science Center has spent the past five years finding the answer to those and many other questions about dogs. Answers came with the recent opening of a show called "Dogs! A Science Tail."

And, yes, real dogs will be there.

"It's really not...just dogs and science. It's really about how dogs and humans are both social animals…because we are both social animals, we've learned to work together," said Jeffrey Rudolph. He is the center's president and a dog lover who worked for years to put this show together.

As he spoke2 just before the show opened, he stopped at a representation3 of a fire hydrant. Next to it is a button. When pushed, it lets visitors smell what a dog smells.

Rudolph said that while humans would just smell dog urine, “a dog can tell what dog was there, what time they were there and actually which direction they were going."

It is one of the ways dogs can decide how safe the area is. It is also how they tell time.

"They have an amazing ability to learn information," continues Rudolph. He says that dogs have 300 million sensory4 receptors in their noses while humans have just 6 million.

Nine similar places in the show permit people to see like a dog does --- not a very colorful display. And, visitors can learn how dogs hear sounds that humans cannot.

They can hear termites6 eating in the wall, Rudolph says.

In the museum, people could watch Garmin, a 2-year-old golden Labrador retriever who is about to complete guide-dog school. He demonstrates his skill with visitors with covers over their eyes. Garmin guides them around barriers in the path.

But do dogs really love us?

"If you look a dog in the eye, a dog will look back at you and you will produce oxytocin," said Diane Perlov. She is the center's senior vice7 president for exhibitions. Oxytocin is the chemical known as the love hormone8 because of the feelings it causes in people.

"And," she adds, "the dog will produce oxytocin in his own body from looking back at you.”

A chimpanzee, on the other hand, will just look away.

So how did the love between dogs and humans begin? Why are there dogs in more than 60 million American houses?

Scientists are not sure. They know dogs came from wolves and that wolves and people crossed paths more than 10,000 years ago, said Perlov. They learned they partnered well in the hunt for food. Could that be the beginning of love?

"It is…our ability to understand each other that forms the basis of our relationship," Perlov says.
