I must say first and foremost that you already have a very nicely developed style. I love how you drew the hind legs (particularly the upper part of the hind legs) and the slope of the back and tail look wonderful. I also really like how the face on the fullbody drawing looks, especially the nose and eyes.

While I love the forward face, I think that your profile view could use a few tweaks. Making the nose and eye appear to be facing forward would especially help. I didn't list it in the redline, but a more gradual slope between the brow and nose can work nicely for defining the shape of the face. Dogs like chihuahuas tend to have a very drastic profile slope to their nose, but more wolfish canines have a more subtle slope.

Really, my only other advice would be to define the ankles more on the front legs. This will especially help with drawing raised front feet since it gives you a better understanding of how the paw will move with the ankle bent. Here's a good picture for showing the front ankle bent
Defining the shoulders more can also help with drawing those raised front legs, but it's not completely necessary if you've got a very fluffy canine (since fur often hides those finer details).

Hope this helps a bit! I really don't think that you need much help, though; your drawing already has very good bones C:

Edit: Also where I've listed "bring back leg forward slightly" I mean just the top half of that leg, the bottom of it looks fine. Moving those top lines forward slightly will help that second leg look more attached to the hip.
