My vet wouldn’t give me the dosage for red mange, said it was too hard to measure.
But did prescribe Bravecto, which is a once every twelve week dosage and it works. But it’s expensive, $50 per dosage.
Bravecto, Credelio, Revolution, or NexGard all get rid of mange.
Most of the time, one dose of Bravecto kills the mites.
The others may take more doses.
I've had a lot of foster dogs treated for mange.
