Betsy (born 2002) is a black and white longhaired Border Collie, credited with being one of the world's most intelligent dogs.
Betsy lives in Vienna, Austria with her owner, who goes by the pseudonym "Schäfer" (English: Shepherd).
[3] Betsy was discovered after her owner answered a request by National Geographic Magazine to submit intelligent animals for study.
[5] Betsy has a vocabulary of more than 340 words,[3][6] which rivals that of the great apes in terms of intelligence and lateral thinking.
[8] Juliane Kaminski, a cognitive psychologist who tested Betsy, hypothesised that her abilities are the result of the use of the Border Collie breed as working dogs, their high motivation levels and that they historically had to pay close attention to their owners' commands when engaged in herding.
