I have a 2 year old Siberian Husky/German Shepard and she does not have any medical problems and never has. As of a few days ago, i noticed what appeared to be like a pimple on the top of her snout. Every day since, it has grown and grown. It is black and circular(almost a perfect circle). At the beginning it wasn't raised, but now it is raised. It is about the size of a dime and raised. I have examined it and looked for answers online, but cannot seem to find anything. It does not appear hollow, so "popping" it isn't necessarily an option. She does not have any spots similar anywehre else on her body. Today, I decided to put hydrogen peroxide and neosporin on it. As I am writing this, I realized the hydrogen peroxide has broken the black circle a part and some of it is coming out. It is not liquid inside, but rather a thick redness inside. Any ideas?
