Λουκάνικο can also mean 'hot dog'?

λουκάνικο sounds strikingly similar to the word we use in Northern Italy for sausage, which is "luganega". I bet they originate from the same word! Lucky me I guess, so I can remember this new word easily

Two questions ago the boy eats an ice cream was wrong and the correction was "the boy is eating". Now the boy is eating is wrong. The only word different here is sausage instead of ice cream. In English both are accurate and have the same meaning.
