One of Our Dogs Is Missing - S1.E13

The women of Lost in Space are featured in their very own episode while the boys are out installing communications equipment. Smith is left in charge (boy is that a mistake) and he "cleans" their weapons, but cannot remember how to rebuild the weapons. This leaves the J2 crew defenseless.

A creepy creature stalks the Robinson women however they think a small dog is to blame for raids on food and other mischief.
