That's a pure bred junkyarddog right there with some big feet. he reminds me of a pup i once found in the road with a broken leg. little mutt never got over 45lbs but he was the best watch dog I ever had. No one got out of their car at my house until I got hold of the dog.
keep him. you'll be glad you did. (as long as you don't have nice carpet)
Real camera wise, if you don't want something big and bulky like a DSLR, and something with interchangeable lenses, Lumix and Olympus make the Micro Four Thirds system, which rivals entry - mid level DSLR's in image quality.
