Chaser dog, a Border Collie, learned over 1,000 words in a single year, including nouns, verbs, and commands. This impressive feat showcases her incredible intelligence and potential.
Chaser's training involved associating words with objects, demonstrating her ability to understand language. Her owner, John Pilley, used a systematic approach to teach her.
Chaser's vocabulary included common nouns, such as "book" and "chair", as well as more abstract concepts like "big" and "small."

Language Is Communication
Chaser's story is a testament to the power of language as a tool for communication between humans and animals. Chaser's owner, Dr. John Pilley, spent four to five hours a day enriching her social and learning experiences.
Language is a gateway to greater understanding, and it's a way for us to communicate with our pets and for them to understand us. This is evident in Chaser's ability to learn and understand hundreds of words.
Chaser's owner, Pilley Bianchi, said that the family receives hundreds of letters from people who are having success in teaching their dog language. This shows that Chaser's legacy is inspiring others to explore the boundaries of language learning and communication.
Chaser's ability to infer the name of a new object by excluding objects whose names she already knows is a remarkable example of her intelligence. This ability is known as "inferential reasoning".
Chaser's favorite toy was a ball named "Blue", and it was also the first word she ever learned. This shows that language can be a source of joy and enrichment for our pets.
Chaser's story is a reminder that language is a powerful tool for communication, and it can greatly enrich the lives of both humans and animals.
Teaching Dogs to Learn
Chaser's story began with her owner, Dr. John Pilley, who was a professor of psychology at Wofford College in South Carolina. He was initially skeptical that dogs could learn language, but his own dog Yasha's problem-solving abilities changed his mind.
Dr. Pilley's research showed that dogs were unable to learn nouns independently from actions. For example, if he told Yasha to get the "paper" in the morning, Yasha would retrieve it, but if he asked her to get the paper inside the house, she was confused.
This led Dr. Pilley to realize that he needed to find words that had value to the dog, and he began teaching Chaser proper nouns using a strategy called "errorless learning." He would name an object, show it to her, and then ask her to retrieve it.
Chaser's favorite toy was a blue ball, which was also the first word she ever learned. By the end of the fifth month, she had learned 40 words and kept them in her long-term memory.
Dr. Pilley's goal was to teach Chaser concepts, not behaviors, and he spent five hours a day with her, always through play. He believed that learning a concept is more valuable than 100 behaviors, because it encourages the dog to solve problems.
The key to Chaser's success was her affinity for words and her passion for shepherding, which Dr. Pilley used as starting points to teach her human language. He took advantage of her natural instincts and innate abilities to motivate her.
Chaser's abilities are revolutionizing the way we think about the intelligence of animals. She can infer the name of a new object by excluding objects whose names she already knows, a process called "inferential reasoning."

The World's Smartest
Chaser, the world's smartest dog, learned to identify over 1,000 proper nouns throughout her lifetime. This is a remarkable achievement that showcases her incredible cognitive abilities.
Chaser's a-ha moment came when she realized that Dr. Pilley's phrase "this is" meant he was going to name something, and she began learning names in just one trial. This breakthrough moment marked a significant shift in her learning process.
Teaching Chaser concepts was infinitely greater than teaching her 100 rote behaviors because once she learned a concept, she was able to use her brain and start to learn by inference. This is the way children learn, and it's a testament to Chaser's intelligence.
Chaser's understanding of categories was also impressive, as she learned groups of categories and could find another ball, for example, by understanding adjectives like bigger, smaller, faster, and slower. This level of understanding is rare in animals, but Chaser made it look easy.
Chaser's ability to learn and understand language was made possible by her owner, Dr. Pilley, who used positive reinforcement and play to teach her. Chaser wasn't an obedient dog, but she knew commands, and Dr. Pilley wanted to make sure she could express herself and have joy in whatever she did.
Chaser's intelligence and abilities were recognized by many, including astrophysicist Neil deGrasse Tyson, who was impressed by her skills. She even appeared on TV shows like "60 Minutes" and "Scorpion", and was featured in major publications.
Brian Hare, co-author of The Genius of Dogs, called Chaser the most scientifically important dog in over a century, and her story reveals just how sophisticated a dog's mind can be.
A Dog's Life and Legacy
Chaser, a Border Collie, holds the Guinness World Record for learning the most words, with a vocabulary of over 1,000 words. She was trained by psychologist John Pilley to learn the names of objects, actions, and nouns.
Chaser's ability to learn words was impressive, with her understanding of nouns and verbs being particularly strong. She even learned to recognize and respond to words like "book" and "table."
In addition to her impressive vocabulary, Chaser also demonstrated an understanding of grammar and syntax, able to learn and use phrases like "get the ball" and "find the book."
Training and Stimulation
Chaser was a charmer and manipulator who loved people, but wasn't too fond of other dogs or cats.
She had a strong sense of self-importance and felt that if you had time to cuddle, you should be playing with her instead. Chaser loved children because they were the best playmates.
To stimulate her mind, her owner would engage her in conversations around the dinner table, asking her about various neighborhood dogs and people. Chaser would respond with growls, barks, or head shakes, demonstrating her understanding of the names and relationships.
She was a quick learner, able to grasp new words in just one trial. However, it took repeated practice for her to commit them to long-term memory.
Chaser's love for "going" on adventures was evident, but she would only move when told where they were headed. If it was to the store, she'd wait patiently in the car, but if it was to a friend's house, she'd be bounding out the door.
Her owner noticed that Chaser's learning accelerated rapidly after she understood that words had meaning. This "aha" moment occurred when she was just 5 months old, and it opened the floodgates for her to learn new words at an incredible pace.

Memory Study
Chaser was able to identify and retrieve 1,022 toys by name, a result of a years-long research effort initiated by John Pilley on June 28, 2004.
At just five months old, Chaser began to understand that objects have names and could pair a novel object with a novel name in one trial.

By seven and a half months, Chaser's vocabulary grew to 200 words, and by 1.5 years, she knew over 700 words.
It took Chaser just three years to learn over 1,000 words, with her vocabulary growing steadily over time under Pilley's training.
Chaser was able to learn new words through "inferential reasoning by exclusion", inferring the name of a new object by excluding objects whose names she already knew.
Chaser's ability to understand sentences involving multiple elements of grammar and to learn new behaviors by imitation is a testament to her intelligence.
At five months, Chaser recognized common nouns such as house, tree, and ball, as well as adverbs, verbs, and prepositional objects.
