Homer tells us Argos's living conditions were less than confortable. He lay "on piles of dung from mules and cattle" and was in a poor state of neglect when Ulysses set eyes on him.
"Infested with ticks, half-dead from neglect,
here lay the hound Argos.
But the moment he sensed Ulysses standing by
he thumped his tail, muzzling low, and his eras dropped,
though he had no strength to drag himself an inch
towards his master. Ulysses glanced to the side
and flicked away a tear..."
Only Poseidon had made Ulysses weep but on his return home, it was his old faithful dog who had the power to make him shed a tear.
