Over the last few years I have taken thousands of photos of our Belgian Malinois, I have found that not using a watermark or copy writing these images there are folks who capture these and use them for a number of posts including scamming people on Craigslist and using on Facebook as profile photos, of course I am flattered however when a person uses your work to bilk other folks out of money it is very discouraging, I will say I take and post way to many photos and I do not really want to ruin the image with a water mark.
