You briefly consider running away, but as you gaze over your half-man, half-dog body you wonder where it is you'd go if you got away. Home? Like this? What kind of life could you live out there alone like this? Meanwhile there's this woman who, in spite of this thing that she's done to you, seems to have genuine affection for you. Would being her pet be so bad when compared to whatever it is that awaits you out there? You breath a heavy sigh as she gets closer and wait apprehensively as your freedom gets further away as she gets closer. You close your eyes as she fastens the collar around your neck. Somehow letting that happen relieves you a bit. You're her pet now, and there's no real point in fighting it, so you allow yourself to enjoy it.
"Good boy." she says "Now come on, let's go home." You follow behind her, now fully hers.
