Telling a Model what to look for

So my name is Praneet, and this is my first post on the forums (quite excited about it actually), and I had a question after completing two lessons of part 1 of the DL course. After attempting to train models do various things, I finally came across something that I thought was just good as a beginner computer vision practice problem. I tried creating a model to tell the difference between a jaguar, a cheetah, and a leopard. After training my model I see that the leopard and jaguars are what get mixed up the most and after doing some research I found out that a difference between the jaguar’s and leopard’s coats is that one has filled in spots while the other doesn’t. Is there a way to tell the model that you’re training to look out for something like this specific feature?
