The shadows have conspired to block out the interesting detail of the dogs. Your going to get hammered anyway because they're domestic pets and not wildlife. It always pays to carefully read the Challenge Description.
It's very hard to see the dogs in this shot. The harsh lighting (ie: direct sun and dark shadow) is very difficult to capture well in digital cameras, but I like the concept behind the shot.
I assume that these are domestic dogs, and not ferals. If so, this does not meet the challenge. The picture itself is a bit chaotic, and the composition is off. Either mush wider, or crop to focus on the jaws of the front dog.
What's all the fuss about? Can't tell what it is that the dogs are interested in (middle left of image). While this is an interesting image I'm not getting the connection to the non-domesticated "Wildlife" part of the challenge. Good luck...
