Just thinking about living with "paunchy" for one year, let alone 5000.. Dunno which one would make person more insane, being with that dog that time, or just being alone. Sometimes that dog is just plain annoying, and sometimes kinda sorta funny.. I guess..?
Tbh it's kinda hit and miss writing an animal companion that way. There was that certain attraction/enjoyment of Pochi at this manga's beginning, but lately it has gotten as fun as an old joke that is told every day.
Mostly all it does it spits out bad jokes and tries being irritating to Asley (and I think to some readers also).
