Talking animal

[4] The term refers to animals who can imitate (though not necessarily understand) human speech.

Alex, a grey parrot, understood questions about color, shape, size, number etc.

[7] Another grey parrot, N'kisi, could use 950 words in proper context, was able to form sentences and even understood the concept of grammatical tense.

[8] Researchers have attempted to teach great apes (chimpanzees, gorillas and orangutans) spoken language with poor results as they can only be taught how to say one or a few basic or limited words or phrases or less, and sign language with significantly better results as they can be very creative with various signs like those of deaf people.

Dogs have limited vocal imitation skills, so these sounds usually need to be shaped by selective attention and social reward.
