Over the years I've run into lots of mouth cancer, benign tumors and infections. We had one about a month ago quit eating, became lethargic and her lower right side of her jaw/mouth swelled greatly. Took a fine needle aspirate of the swelling and discovered no abnormal cells but did find some signs of infection. A round an antibiotics & pain medication was prescribed and so far it appears to have cured her.
The vet didn’t give him antibiotics but I’m going to call tomorrow and ask for some. I’ll keep everyone posted on if it gets better. I hope it’s just an abscess!
