- With their swiveling ears, dogs can locate the source of a sound in 6/100 of a second.
- Dogs have far fewer taste buds than humans, but the 200 million scent receptors (compared to our 5 million) in their nasal folds nevertheless make some of them very finicky eaters.
- The hair on a dog’s muzzle, eyes, and jaws are touch-sensitive hairs called vibrissae that can sense tiny changes in airflow.
- Dogs have 39 pairs of chromosomes. Humans have 23.
- Dogs have about 10 vocal chords. Cats have more than 100.
- Studies show dogs can learn to distinguish up to 100 words.
