Border Collie Knows More Than 1,000 Words

A border collie in South Carolina has quite the vocabulary, with more than 1,000 words in her arsenal!

Chaser’s owner, a retired experimental psychology professor, spent three years teaching her 1,022 proper names for various objects.

With the help of a colleague, it was found that not only does Chaser understand that objects have names, but also that an object may have more than one name.

The results of their work with Chaser has been published in the journal Behavioural Processes.

Chaser’s owner said she is so enthusiastic about learning, that he has to go to bed at 8 p.m. just to get away from her.
