Place it right after the reveal of the loss in your edit, then follow it with Emotional Damage for a second reaction before a short Bruh closes the joke. The Sad Meow Song also works in a later scene when the mourning needs a softer echo.
About this sound
This is a loud spoken line, lasting just over a minute, in which a voice announces that he has just lost his dawg and stretches the grief into an over-the-top lament. It feels raw, dramatic and painfully funny at once, like a public breakdown played for laughs, with the volume turned up until the sadness becomes absurd.
