She Was Clear for a Month, Then It Came Back: A Reader Asks About Recurring Mange on a Budget

Hi. I have an adult 7 yr aussidoodle. I rescued her and we have been fighting mites and yeast for months. We treated her for mange. She has a bad immune system. She was close to death when I got her. I'm poor I've spent tons on vet bills. I don't have $ to try treating her for love.

She was clear for about a month. No scratching. She lose a lot of hair. Something still seems to be eating at her. Is there anywhere that might have an over the counter product that works. Prior at the beginning the vet ordered bravecto. I worked on her coat forever. She had oval off white things all over in her hair. She would shake and my house was covered in them. I have that almost cleaned up but now she's scratching herself crazy and shaking constantly. Do I need the bravecto type pills again. It was like $130 that I just can't afford or another dr visit. Since I've had her I've had huge problems with sores and bites from head to toe. All derms say I'm delusional. I'm literally saturated with what has to be scabies or some kind of mite. I don't even know where to start. I'm killing myself trying to wash bedding daily cleaning and trying to figure out if it is dog lice. If it were on her a long time could it mimic mange.

Now I'm wondering if all the hair and follicles literally falling out we're actually lice all along. I've tried it all to the point her hair was gone in big patches I think they were chemical burnsfrom all the medicated shampoo ⁰The vet said stop everything. She seemed fine then wham here we go again. Anything I can try that won't burn her? Poor pup.
Thanks

Some Thoughts on Recurring Dog Mange From Our Publisher

Hi Trace,

I'm not a Vet, but I can provide some things you should consider:

Why mange keeps coming back

A dog with a compromised immune system (which mange itself can cause, and which mange can also worsen) often needs longer or repeated treatment courses than a healthy dog would. A month of being clear followed by a flare-up is a classic pattern with:

Incomplete treatment — mites can take multiple dosing cycles to fully clear, especially demodectic mange in an immunocompromised dog.

Reinfestation from the environment — mites and lice eggs can survive in bedding, carpet, and furniture for a while, so if the environment wasn't fully treated alongside her, she can pick it back up.

A different parasite than originally diagnosed — sarcoptic mange, demodectic mange, and lice all look similar on the surface but need different treatments. The "oval, off-white things" shaking out of her coat could be lice eggs (nits) glued to the hair shafts, or mite eggs/debris — Cheyletiella ("walking dandruff") looks a lot like this and is sometimes missed. This detail matters a lot for treatment, which is why one more diagnostic step is worth pursuing if at all possible.

One thing that might be worth prioritizing over a full exam

A skin scraping and a piece of clear tape pressed on her coat, examined under a microscope, is usually cheap — often bundled into a basic visit fee or offered as a low-cost add-on — and it can tell you definitively whether you're dealing with mites, lice, or something else. Without that, treatment is essentially a guess, which is how people end up cycling through products that don't match the actual problem.

On using Bravecto/isoxazolines

If it was working before and symptoms are back, that generally points to either the parasite not being fully eradicated (needing another dose) or reinfection. These systemic chewables (Bravecto, Simparica, NexGard, Credelio) are considered the most effective class of product for mange mites and lice — over-the-counter topical treatments (store-brand flea/tick drops or sprays) generally do not kill mange mites or lice effectively, so switching to OTC now would likely mean spending money on something that won't fix it and losing more time.

Possible lower-cost paths to that same medication:

Ask your vet if they'll sell just the chewable without requiring a full exam visit, given she's an established patient.

Chewy, Costco pharmacy, and 1800PetMeds sometimes price lower than in-clinic, and some will fill with a vet's fax/phone authorization instead of a full visit.

Ask about generic fluralaner/afoxolaner — often notably cheaper than brand-name Bravecto.

Low-cost vet clinics, vet school teaching hospitals, or ASPCA/Humane Society clinics can sometimes offer scraping + meds for less than a private practice.

RedRover Relief, The Pet Fund, and local breed rescue groups (Aussiedoodle/Poodle rescues especially) sometimes have small grants for situations like this — worth a few emails even if it feels like a long shot.

One thing that seems worth avoiding - heavy medicated shampoo

Heavy medicated shampooing on your own right now seems like it could add risk — it sounds like it may have already caused irritation or chemical burn on her skin, and stripping the skin barrier further could make a mite or bacterial/yeast issue worse rather than better. A gentle, vet-approved sensitive-skin shampoo (or even just plain lukewarm water rinses) seems like a safer choice for now, letting the systemic medication do the actual parasite-killing.

The daily washing and cleaning you're doing is genuinely the right instinct for breaking a mite/lice cycle in the home — that effort isn't wasted. The missing piece seems to be getting the right medication back into her system and confirming exactly what's going on, so treatment isn't a guess.

All the best and let us know how things go.
