I just love the lighting and the textures you may have used <3 I suggest looking at dog skulls and muscle anatomy to help with finding out where the ears and jaw go. Other than that everything else is just stunning! I'm just loving it, watching you bloom and all <3 Also, since its not really skin, the shine wouldn't really be like that on a dog's fur. Making it blurry is definitely the best way to go. Sort of the same with the hat, unless its a hard hat and all XD I hope this helps you out lots!
