What would you recommend for a dog with demodectus mange?

She has been treated for months now with Mitaban Dip at the vet’s office and on antibiotics. She was showing signs of it getting better, but when we try to back off on the Dips and Antibiotics she gets bad again. The vet has said we may need to consider an an oral medication, but there can be severe side effects from it for her and we really don’t want to do that to her.

Have no idea what your vet is talking about. The dips are expensive and dangerous. The oral meds are safer and work better. He could have used a low dose Ivermectin and cleared up the problem if that is truly what it is.
And how many skin scrapings has your vet done? Are they all positive for mites? If not, why is he not investigating other avenues, like allergies, or a secondary bacterial infection, which cannot be treated with a dip? Why is he treating Demodex with an antibiotic? That does nothing for mange.
I hope you have not spent a ton of money on those dips, and meds, but if you have, please find a new vet.

The definition of insanity is to keep doing the same thing over and over again, expecting to get a different result….
