Puppy 'talk' with their tails. The situation of the tail can reveal to us a considerable measure about how a puppy is feeling; hung low proposes dread and accommodation, while held high is an indication of strength and excitement. A swaying tail frequently passes on bliss and fervor, however neuroscientists at the University of Trento in Italy have discovered that the speed and course of sway is essential in determining if the puppy is either adversely (ease back and to one side) or decidedly (quick and to one side) invigorated.

In 1957, Laika became the first living being in space via an earth satellite and JFK’s terrier, Charlie, fathered 4 puppies with Laika’s daughter.
But i think Laika's journey in space was horrible and she never returned back to earth.
