big dog

My outing today included a stop by the lake to be in nature and to take some pictures. None of the usual birds were there, and I didn't look for the alligators. What would I photograph . . .
A woman pushing a child in a stroller walked by, and this big, friendly dog walked respectfully beside them. When the little one got out to play, I asked if I could take a pic of the dog. She said yes and good luck as he was on the move!
