Human Factors
First Officer was flying a visual approach at night to 31L at DAL.  As we were turning final abeam downtown; we got a Caution Obstacle Warning. The First Officer initiated a go-around and as soon as he did the caution obstacle warning stopped. I had him continue the approach to a landing with no further warnings occurring.  Because it was night; we should have continued the go-around even though the warning had stopped.
We were approaching MYLES from the east and cleared for a visual approach to Runway 31L. We were initially at 3;000; and slowing to 170 knots; and descending to 2;200 about 4 miles out. We configured to gear down; and flaps 30; and I clicked the autopilot off; and turned inside JAKID; in a turning descent.We were roughly on glide path; and centerline rolling wings level; when we got a GPWS caution 'too low obstacle'. I initiated a go-around; and as soon as I pulled up and added power; the caution stopped and light went out. We elected to continue with the approach when we should have performed a go-around.
Flight crew reported they failed to follow SOP after receiving a GPWS obstacle caution while on approach to DAL.
