Find art styles that you like and want to draw like. Look at their art and try copying one of their pieces as exact as you can (if you post it somewhere, make sure you give credit). This will help you remember how they drew, and can help you get better. Do this with more art. You can focus on just certain parts of styles too, like if you want to mostly draw like one person but draw paws like someone else. Try to draw your own things in the styles you see. Put your own spin on it. Eventually, you'll get better, and one day you'll have your own style, distinguishable from the ones you copied from.
This is what I've done.Here's a link to my DA list of art that I like. When I draw I look at some of it and try and copy small things.
