Inu ga Hito ni Naru Hanashi - Vol. 3 Ch. 24.5 - Your Dog Become a Human! (Ai-chan - Doberman ♀) 3

actually an interesting philosophical question

It's even graph-able on an XY-plot, with (0, 0) being full dog + full dog body and (100, 100) being full human + full human body, then one could shade a Region of Acceptability, etc.

apparently it's called the harkness test XD

(tho i guess plenty of dogs humping their pillows/plushies lol)
