I'm not sure exactly how he got it or exactly how long it has been there. My mom was taking care of him when I was in the hospital... but I was in the hospital for at least 7-8 months and I've been home since about February... so maybe a year?
I know that I should have taken him to the vet sooner, but I have been in the hospital for a while and got out a couple months ago, my mom was taking care of him... I would have taken him to the vet if I wasn't in the hospital.
I have no idea what this is on his nose, it's been like this for a while, and I thought it would go away. I was wrong. He isn't doing good. I am not sure what to do, I wanted to ask on here before I took him to the vet.
