I would say that it looks like ringworm. My little snoopy had the same ype of spot on his nose when I got him . It got worse and within three days the spot had come loose and he lost the fur in that area. I took hm to the vet and got meds . His fur has finally come back . If you would like the name of the meds let me know . They worked really well . In three days I saw alot of improvement.
