Hello Vets and Thank you in advance ! Several days ago , I notices 4 spots on my dogs stomach. 3 are very tiny , and the largest is the size of a nickel . Originally it looked crusty, and I bought both a shampoo and spray that is both antibacterial and antifungal . Ive used it for two days , and when I used it , the crust dissolved and this is what the spot looks like . Does this look like ringworm to you ? If he doesn't clear up in a few days after using the shampoo and spray I will take him to his Vet. I don't know where he would have came into contact with anything . He is an indoor dog. Only goes out to potty . Any thoughts are greatly appreciated .
