Why does my dog cry when the other dog cries?

right now my husky is outside and he wants within the house so he is at the door crying and my other dog is upstairs and started to cry when he heard my other dog crying.

my husky stopped crying but my dog upstairs wont stop.
does he feel bad for my husky?
Answers:    He's lost his buddy, its a change for both of them and they might feel lonley without respectively other and can get depressed!
Pack animals will certainly be concerned about one another. Hope you permit him in.
Help beside puppies please?   Should i obtain a Chinese Crested, Dachshund, or King Charles Spaniel?   What's your favorite sighthound breed?   For the general public that live contained by Bama..where on earth is an SPCA?
