Any ideas on what we are looking at here?
So here are the stats: 13.5 year old beagle/shepherd mix, around 35 lbs
About a month ago, we went to the vet for coughing fits. Did an x-ray and found pneumonia. He was on a few medications for the infection and was given a nebulizer. He also had a growth on his right back leg, but that turned out to be arthritis after the x-ray.
Yesterday I find the attached in the photo. It also looks like the left side of his lip has been protruding from his face. He is getting another x-ray and possibly an aspirate this weekend. I just wasn’t sure if anyone had any clues about what it could possibly be?
