Hi. My male boxer has a large red round sore under chin. I’m not too sure what it is or how to treat it. He’s eating and playing as he normally would. Thanks

Poor Brax. This looks more like a mass than a true "sore". Since this is a new finding, I would strongly recommend have it checked out by your vet. Your vet should be able to aspirate it and make sure there aren't any scary cells present. Boxers commonly get tumors called mast cell tumors which are malignant but can be curative if diagnosed early and surgically removed. Your vet should be able to easily rule this in/out and recommend the best treatment for him whether than is to surgically remove it or to just watch it. I hope this helps!
