I seriously doubt that this is from food. I would ask the vet. It looks to me like her harness is also causing some irritation. Maybe the whole thing is related?

Oh, that third picture sort of looks like she might have a staph infection. Since this is on her legs and belly, I would be more inclined to think it is from grass. When they scratch, they end up with infections. Definitely needs to be seen by the vet imho.
