I just got a little pastel girl , I noticed she has some mouth rot and I'm currently treating it, but I noticed something I'm not familiar with, can you please tell my what it is, it's located under her chin. all her scales under chin are grayish, it's all in a spot about half an inch in diameter. any help would be great.
tips on treating would be best, I'm many hours away from the nearest vet, but if I have to, I will go.
