Hope this will help, sorry for messiness; I'm not very experienced using a mouse. ^^'
Here's a few things that might help make your style a little more realistic:
- Use proportions and leg stances that are more even- maybe look at a picture of a real dog or wolf to help with that
- The eye could be smaller and more angled; if you're going for more realistic over cartoonish/chibi, then I would look at more details surrounding the eyes
- The paws are kind of hard to describe- once again, if you want to add more detail, images are probably your best bet
Overall, I would advise you to study the structures of dogs and wolves from real life and practice at different angles. I hope this could aid you in some way! :3
EDIT: I added paw and eye references as well if that helps!
