They studied a rare group of dogs that had learned the names of many different toys. They called them 'gifted word learners'.
When their owners asked for a toy by name, these dogs tilted their heads far more often than typical dogs did.

The researchers think the tilt may be linked to dogs paying close attention and trying to match a word to something they remember.
