Can Ring Worms Be On A Dogs Stomach?

Ringworm is not a parasite, its a fungal skin infection. So yes it can appear on a dogs stomach, but its more likely to be a sting or bite of some sort, even a nettle rash. Try using an antiseptic cream (even diaper cream) for a couple of days and if it doesn't help get it checked by a vet

Yes it is a fungus, but you need to treat it with an antifungal  cream like lamisil.  you should treat it twice a day for 3 weeks or more, be careful for it can spread to you also!  go to wal-mart and buy some jock itch cream and use that.  thats what we recommend in our clinic.
