[Ans] Why were dogs removed from Antarctica on Feb. 22, 1994?

Step 1 : Introduction to the question "Why were dogs removed from Antarctica on Feb. 22, 1994?"

A clause in the Antarctic Treaty required the dogs' removal in 1994 because of fear that the disease distemper may spread to the native seals.
