So, dogs have a better sense of smell than humans. They have better eyesight than believed before, as they may be able to discern some colors, which is probably why our Cocker Spaniel barks at the HDTV almost constantly and the Chihuahua watches it while sitting on one of the humans. However, while dogs also may have a better sense of hearing, they do not have any real comprehension, although the previously mentioned Cocker Spaniel hates most current pop music (“Good dog, Murphy!”).
Most dogs do have a limited vocabulary (“Sit”, “Stay”, “Dammit!”), but that’s about it. This explains why two of my dogs could get into a major snarling match while “(What’s So Funny ‘Bout) Peace, Love and Understanding” was playing this afternoon. Irony, anyone?
