But what about Ralph, the Pug?

He's one of 34 dogs that faced a similar test of empathy.

Help!

Kiki was another.

And there was KOOZA!

Help!

Each dog had to solve the same problem: What to do about an owner apparently trapped behind an easily opened door?

The dogs reacted in all sorts of ways.

Some became anxious and circled the room, repeatedly.

Others headed to a door at the back of the room where the researchers were, perhaps hoping for some human help.

Others just stared.

Some dog owners cried, indicating distress.

Help!

While others hummed "Twinkle, Twinkle Little Star," and said "help" in a tone that carried no emotion.

Help.

Some of the dogs, like poor Kiki, were so anxious that they may have even interfered with their ability to act.

She was one of the dogs that didn't complete the test, as was the case with several others.

Overall, more than half the dogs opened the door.

Surprisingly, the dogs with crying owners didn't do any better than the ones with calm owners.

But speed told a different story.

The dogs with crying owners opened the door three times as fast.

Hello, my KOOZA! Yeah! All right.

But what happened to Ralph, the Pug?

Was it all too much for him?

Of course not.

Never underestimate a Pug.
