Hi everyone, I’d like some advice regarding a lump in my dog's mouth (a 10-year-old Gordon Setter who is usually in perfect health).
I noticed a small red spot in his mouth about a week and a half ago, near the gums or the cheek. At first, it was really tiny, but it's been getting bigger gradually, though it seems to have stopped growing in the last two days. However, it's still bleeding a little bit.
I'm worried because it grew quite a bit in a short space of time, even if it has plateaued over the last couple of days. Has anyone else seen anything like this on their dog? What could be the possible causes?
I know you can't give a diagnosis just from a photo, but I’d appreciate some opinions and to know if this might be urgent—is it worth booking an appointment with the vet? I've seen similar sores on other older dogs before; could it just be down to age?
