ok so basically dogs in general have a few common traits, that being pointy noses, a smooth slope of the nose, and a small, square shaped chin. you can also give them fuller ears to make it more realistic.
one of the best help in drawing dogs is studying my own dogs and looking at reference photos. studying dogs and getting a realistic foundation on how they look is very helpful.
if you keep practicing you're sure to become better very fast.
when i first started drawing i wasnt ever happy with my results, but as time went on and i practiced every day,then i found myself becoming more and more proud of my finished works.
just keep drawing because you're doing good :) <3
