Did We See A Sundog Near Scanlon Saturday Afternoon?

The picture doesn't do the phenomenon justice.  As we were driving southbound on I-35 to the Carlton VFW to volunteer at the monthly steak fry Saturday afternoon I saw this small rainbow-like light in the sky.  I said it was a sundog and my husband, Homie questioned me on what a sundog is.

Good question since I really didn't know, I just remember hearing the term.  What we saw appeared to be a small rainbow with only 2 colors and was near the sun, but there wasn't any rain or moisture.  Although, I thought there might be moisture in the atmosphere that could be causing it.  So, what IS a sundog?

Wikipedia says that a sundog is:

a member of a large family of halos, created by light interacting with ice crystals in the atmosphere. (IT WAS COLD, SO THAT MAKES IT POSSIBLE). Sun dogs typically appear as two subtly colored patches of light to the left and right of the Sun, approximately 22° distant and at the same elevation above the horizon as the Sun. (IT WAS ON ONE SIDE OF THE SUN, BUT I DIDN'T KNOW ENOUGH ABOUT SUNDOGS TO LOOK TO THE OPPOSITE SIDE OF THE SUN TO SEE IF THERE WAS ANOTHER ONE).  They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sun dogs are best seen and are most conspicuous when the Sun is close to the horizon. (IT WAS CLOSE TO THE HORIZON BECAUSE IT WAS ABOUT 5PM, SO THE SUN WAS SETTING).

So, here's my take, there's no concrete evidence since I neglected to look on the other side of the sun for another sundog that would form a halo around the sun.  But, everything else seemed to fall into place, so I'm going with "yeah, I believe I saw a sundog".  Have you ever seen one?
