Ultravate is a strong cortisone cream. Cortisone makes fungus worse, so if the fungus hasn't been responding, that could certainly be a good reason.
Econazole is a good antifungal cream. Regular use on all spots should clear things up nicely. If it doesn't, then your doctor would need to think about a short course of oral antifungal antibiotic. The fact that you say such a course did not solve the problem suggests that there could be a fungus reservoir in the house. Dogs are uncommon but possible. Despite the negative check, I'd look the dog over again and have a vet look too if there's any doubt.
It's also possible that these round lesions are eczema and not fungus. Of course, the doctor founbd a positive scraping, but these can sometimes mislead. If a fungus culture hasn't also been done, I'd recommend one, for your daughter and for you too. Eczema can look round and "ringy" and tends to recur from time to time, and runs in families. Just maybe, it's been eczema all along . . .
Best.

my grand daughters get ringworm from cats and dogs.....it seems as though all they have to do is look at one...and they get it.it takes so long for over the counter meds. to work.an old man we know told us of a home remedy and it was like a miricle for ring worm.you take sulfer and mix it with just enough margerine to make a paste.....it dosnt take much of either(1/2 teasp.)and put the paste on the ring worm.....(the margerine is just to hold it on)leave it for about 15 mins. and rinse really well.its gone with in two days.if the sulfer burns....rinse immediatly.it didnt burn on my granchildren (4 and 3 years old)......but he said some people may be sensitive.you can get sulfer in a bag from just about any place that carries garden supplies......you can also treat your dogs with sulfer,(no margerine)just take care not to get it in thier eyes....read the directions on the bag for dogs.he also told us about mixing clorox and water for poison oak....another fast miricle....lol.
