Puppies are a joy to behold, but with that joy comes responsibility. Regardless of what kind of puppy one has, the same general rules apply when caring for a pet. Like people, all puppies have different personalities, and no two are exactly the same. For this reason, owners of new puppies or dogs will have to take time to get to know them, to build trust, and to discover what actually motivates them. Experts explain all the necessary steps to ensure that a puppy grows up to become a healthy, well-behaved, and much-loved addition to a family. NOTE: Bonus material follows main feature.

New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.
Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
