The correct answer is Salamano mourns for his dog.
In The Stranger, a 1942 novel by French writer Albert Camus, Salamano has an old dog that suffers from scabies, and frequently insults and hits his pet. However, after Salamano loses his dog, he cries and longs for his return. His pain at losing his dog contrasts with Meursault's indifference to losing his mother.
