How many words can a dog typically understand?

Dogs can typically understand 80-100 words, comparable to a two-year-old child. However, with training, some breeds demonstrate exceptional linguistic capabilities. Border Collies often rank as the most intelligent dog breed, with one named Chaser understanding over 1,000 words, including proper nouns and object categories. This remarkable ability highlights the potential for dogs to learn a significantly larger vocabulary than the average pet.
