WONDER QUESTION: Why does a dog's nose turn pink?


 * Dogs' noses become pink because of the loss of pigmentation or as a sign of old age. The most common cause of "snow nose", which is when they are pink, is that the dog is not getting enough exercise.
 * The purpose of the star-nosed mole's nose is to blow bubbles under water (10 bubbles per second) to smell their food.
 * The star-nosed mole's nose is also a tentacle-like stucture that is filled with blood vessels.
 * The star-nosed mole perfers to live in wet wooded areas or swamps.
 * Dogs eat grass because their stomach hurts, and the grass makes them throw up. When they do, their stomach no longer hurts.
 * Dogs feet smell like Fritos because the heat of a dog's body causes an odor that happens to smell the same as Fritos do!
 * A dog's "Frito-smelling" feet usually occurs after the dog takes a nap.
