Hmm Stink bait for catfish sounds worse.

Wet dog food is always precooked and sterile, a human "or anthro fur" can eat dog food with no real danger. Stink bait on the other hand has no standards, it can be rancid or worse. Dog food is better for kinky petplay / humiliation scenarios, Stink bait is potentially hazardous.

My vote is to keep your face in the wet dog food until it soaks all the way into your fur.. Then it gets dunked into dog shit.

My hope is that it helps you appreciate the nuances of flavors in the dog shit.
