What does Argos do when he sees Odysseus?

Appearance: Lying neglected on a pile of cow ...

Known: Speed and strength and his superior ...

Species: Dog

Born: Apyoc

Explanation:

As Odysseus approaches his home, he finds Argos lying neglected on a pile of cow manure, infested with ticks, old and very tired ... Unable to greet his beloved dog, as this would betray who he really was, Odysseus passes by (but not without shedding a tear) and enters his hall, and Argos dies.

Argos recognizes Odysseus at once and he has just enough strength to drop his ears and wag his tail but cannot get up to greet his master.
