My entry for the dog sprite challenge. Still have a long way to go for my pixel art. I don't know how to dither properly, stick with a color palette, or make smooth animations, but I'm going to keep practicing.
I see you went for a japanese dog here :p
It is a good start, maybe a bit exaggerated on the dithering part. Also, try avoiding very light outlines: it actually reduces the impression of volume ;)
