Since you first noticed the "bumps" on your dog, have any new ones shown up? If not, perhaps you won't have to do anything at this time. Since we don't know for sure what these spots are, you should still watch them for any changes. Certain skin infections will be self-limiting and resolve pretty well without any medication.
On the chance that this was a fungal infection, I would suggest you still keep small children from contacting your dog and you should be sure to wash your hands after touching her.
Have you checked with any of the animal shelters or humane societies in your community about whether or not they are providing any medical assistance for pet owners with financial difficulty?
No other spots have come up. Only the three existing ones. and they are just bald spots now. And my husband is a medic in the military,and he doesn't think it is ring worm since he had it a couple times as a child.
