I felt like making some items for people to use, so I decided to go with dogs. :P
Anyone wanting to start up a dog adoptable site can use and edit the sprites below. I made very simple sprites so that they are easy to recolor and add your own patterns and coat designs. You can do whatever you want with these sprites except claim them as your own.

Again, you can edit these to your liking and I encourage you to edit the dogs so that you have more variety. You can easily edit them in MS Paint with the Bucket tool. (:

may shade and detail everything here in the future, but I'm not sure yet.
