Do dogs understand human words or just the tone of voice?

Dogs understand both human words and the tone of voice, integrating these cues for a more complete understanding. Research indicates specific brain regions activate for familiar words regardless of intonation, while other regions respond to the emotional tone. For instance, a Border Collie named Chaser learned over 1,000 unique nouns, demonstrating an impressive capacity for word comprehension. This ability contributes to dogs' ranking among the most intelligent animals, often compared to a 2-year-old human in terms of cognitive ability.
