Chaser - The World's Smartest Dog
A dog named Chaser is the world’s smartest dog as he knows 1,022 individual item names. This is largest amount of known items by any animal, even more than the legendary Alex the parrot. Psychologists Alliston Reid and John Pilley make a test, to know the limit of words Chaser can learn.
They said that "In the first experiment where we talk about the learning of proper nouns, the procedure we use is one where she was taught in a way that she couldn't fail," Pilley said. "We would place the object right on the floor, somewhere the dog couldn't miss."

After period of several months Pilley and Reid would work with a different object.
"Most people when they try to teach a dog, they put too many objects on the ground. That's called simultaneous training," Pilley explained. "Our method was a successive technique."
The pair regularly tested Chaser on her vocabulary by putting random groups of 20 toys in another room and having her fetch them by name. Chaser, now 6, never got less than 18 out of 20 right, in 838 separate tests over three years.
