Hello all! I am a new Guinea Pig owner and am just IN LOVE with my new little friend. I noticed today that there was some crusty and red skin above his nose and it made me concerned. I have attached one photo which was the best I got but still not great, hopefully you can zoom in and get an idea of what it looks like. He has been active and totally himself and I havent noticed him scratching or rubbing on it. Any advice would really help, thank you!
