Demodex need not be expensive to treat. It also is not, in my opinion , a condition that warrants a return of refund of a puppy. Unless it is generalized and non responsive to meds.
If your Veterinarian is advising you that <localized> Demodex is expensive to treat and is also suggesting an expensive treatment regiment, he may not have your best interests at heart. Here is a post that I made some time ago that explains what Demodex is and if you read all the way to the end, suggests low cost treatment options.
Demodex (mange mite) Species
Canine Demodex canis Demodex injai Demodex sp.
Feline Demodex cati Demodex gatoi Demodex sp. Overview of Life Cycle
* Most Demodex spp. are considered normal mammalian fauna. * Neonates are thought to typically acquire mites from the dam via direct skin-to-skin contact, but most individual animals do not develop clinical disease. * All stages of the life cycle (eggs, larvae, nymphs, adults) reside within the lumen of hair follicles and within sebaceous gland ducts; some species are more commonly found in the stratum corneum. * Development from egg to adult takes approximately 20 to 35 days and is completed entirely on the host.
(Go to top) Stages (see images on right)
* Six-legged larvae hatch from fusiform-shaped eggs and undergo several molts to become eight-legged nymphs and ultimately adults. * Adults are eight-legged, slender, and elongated mites; their appearance is often described as cigar-shaped. * In the canine Demodex species, the length of adult mites ranges from 180 to 210 µm for D. canis, 330 to 370 µm for D. injai, and 90 to 140 µm for the unnamed species. * In the feline Demodex species, the length of adult mites ranges from 181 to 219 µm for D. cati and 81 to 115 µm for Demodex gatoi.
(Go to top) Disease
* Although most Demodex spp. are considered normal mammalian fauna, overgrowth of mites may be associated with development of patchy hair loss or mild to severe dermatitis in dogs and (less commonly) in cats. * In cases of demodicosis caused by the unnamed canine Demodex sp. or D. gatoi in cats, disease is thought to be caused by the infestation itself rather than an overgrowth of mites.
* Canine demodicosis may be localized or generalized and both forms may present in either juvenile or adult dogs. * Pruritus does not occur in uncomplicated infestations; however, pruritus can be seen with secondary bacterial pyoderma. * In dogs, localized demodicosis—characterized by a mild, nonpruritic, patchy alopecia on the head or limbs—usually develops in puppies less than 6 months of age. Most cases of juvenile-onset localized demodicosis resolve spontaneously without treatment. * Generalized demodicosis in dogs is a moderate to severe disease that in most cases is attributable to an overgrowth of mites believed to occur because of an underlying systemic disease or immune defect. With the unnamed canine Demodex sp., however, the infestation itself is thought to cause disease. * Physical examination findings include alopecia (which may involve several large to coalescing areas of affected skin), erythema, and often secondary superficial or deep pyoderma. Lymph nodes may be enlarged, and when pyoderma is present, pruritus may develop.
* Cats with localized demodicosis develop alopecia and crusts as well as some scaling around the face, neck, and eyelids, with varying degree of hyperpigmentation. * Generalized demodicosis due to overgrowth of D. cati is usually associated with underlying systemic disease (e.g., diabetes, Cushing's disease, neoplasia, feline immunodeficiency virus). * Cats infested with D. gatoi are pruritic and may excessively lick or groom affected areas. In cats with D. gatoi, dermatitis is not associated with underlying disease.
(Go to top) Prevalence
* Canine demodicosis (demodectic mange) due to D. canis is a common skin disease in the dog; disease due to D. injai or other Demodex sp. in dogs appears to be very rare. * Feline demodicosis due to D. cati is rare, and feline demodicosis due to D. gatoi is even less common, although cases are reported from the southeastern United States.
(Go to top) Host Associations and Transmission Between Hosts
* Demodex spp. are host-adapted mites of mammals. Mites have not been shown to cross-infest among dogs, cats, and humans. * Neonates are thought to acquire mites from their dam via direct skin-to-skin contact during nursing. * Transmission of mites may also occur during direct contact between older animals, but demodectic mange is not contagious as most animals that develop generalized demodicosis are thought to have an underlying immune defect (see Disease). * Demodex gatoi is a superficial species reported from cats and is thought to be contagious among cats.
(Go to top) Site of Infestation
* Demodex canis and D. cati infest hair follicles and sebaceous glands. * Mites may occasionally be reported from other tissues (e.g., lymph node, intestinal wall, kidney, thyroid gland) following dissemination via blood or lymphatic drainage. * Early studies of nursing neonatal puppies have found D. canis mites initially within the skin of the face, and then over time mites are transferred throughout the skin of the entire body. Mites are not found in the skin of stillborn puppies or puppies born by Caesarian that are not allowed to nurse. * Localized demodicosis in dogs most commonly develops on the head or limbs; the lesions of generalized canine demodicosis may develop anywhere on the body. * Demodex gatoi infestation in cats is most frequently reported from the groin, ventral chest, and sometimes limbs.
(Go to top) Pathogenesis
* The immunopathogenesis of demodicosis is not fully understood, and in most cases an underlying cause is not identified. Although a responsible condition is not always identified, many cases of generalized demodicosis appear to be the direct result of underlying diseases that compromise the immune system. Excessive cortisone, chemotherapy, and underlying cancer or diabetes have all been associated with the development of generalized demodicosis in individual animals. Accordingly, dogs and cats with generalized demodicosis should be carefully evaluated for potential underlying disease states. * No specific deficits in innate or humoral immunity have been identified in dogs with generalized demodicosis. However, some studies suggest that cellular immunity may be compromised in some individuals that go on to develop generalized demodicosis.
(Go to top) Diagnosis
* Demodicosis due to D. canis, D. injai, and D. cati is diagnosed by microscopic examination of deep skin scrapes from affected areas of alopecia (Link to Images). * Alternatively, in uncooperative dogs or sensitive areas in which skin scrape is difficult (e.g., feet, interdigital region), hairs may be plucked from an affected area and placed in mineral oil on a slide for microscopic examination. * Because the unnamed canine Demodex sp. and D. gatoi in cats reside within the stratum corneum, superficial skin scraping or tape impression offers a better method for detecting these mites (Link to Images). Because the pruritus associated with D. gatoi infestations leads to removal of the mites by grooming, they often are difficult to find. * In rare cases of “occult demodicosis,” i.e., no mites are observed with either the skin-scraping or hair-pluck techniques, a skin biopsy may demonstrate Demodex mites. The mites (or mite fragments) can be seen within the lumen of the hair follicles or (rarely) within the sebaceous glands/ducts, depending on the type of mite. This technique may be necessary in Demodex cases involving the feet and in the Chinese Shar Pei.
(Go to top) Treatment
* Most cases of localized demodicosis resolve spontaneously without treatment. * If treatment is desired, a rotenone-based insecticide ointment (Goodwinol) has been approved. Although the ointment is miticidal, localized irritation may occur.
* Generalized demodicosis may require extended, aggressive therapy to resolve disease. * Comprehensive treatment should include use of an effective miticide, evaluation for any underlying disorders and appropriate treatment when found, antibiotic therapy when pyoderma is present, and spaying of female dogs to prevent recurrence during subsequent heat cycles. * Amitraz dip (Mitaban®) at 250 ppm every 2 weeks is the only approved miticidal treatment for generalized demodicosis in the United States. o Hair should be clipped throughout treatment; dogs should be allowed to air-dry or should be dried with a blow dryer after each application. o Use of a benzoyl peroxide shampoo prior to the application of amitraz dip is recommended; dogs should not be shampooed between applications. o Some practitioners recommend weekly dips or a more concentrated formulation (e.g., 500 ppm) in refractory cases or to clear dogs more rapidly. o Side effects may occur and are detailed on the product label. o Key safety recommendations when using amitraz dip include application of the product in a well-ventilated area and use of protective gloves and a mask during application. o Asthmatics and diabetics should exercise particular caution when handling dogs that have been treated with amitraz. * Other miticidal treatments not labeled in the United States include high-dose oral ivermectin, oral milbemycin oxime, and topical moxidectin. o Ivermectin injectable may be given orally at escalating doses using 100 µg/kg increments. Begin with 100 µg/kg for 3 days followed by 200 µg/kg for 3 days followed by 300 µg/kg. Some practitioners recommend remaining at the 300-µg/kg dose whereas others recommend continuing to increase the dose every 3 days to 600 µg/kg. It may take up to 33 weeks to resolve lesions and eliminate mites. Continue treatment for 1 to 2 months after two consecutive negative skin scrapings.Milbemycin oxime (Interceptor®) has also been used daily at doses ranging from 0.5 to 2 mg/kg. Doses are escalated gradually, building to a final dose of 1.5 to 2.0 mg/kg (Holm, 2003). Continue treatment for 1 to 2 months after two consecutive negative skin scrapings; the treatment course ranges from 60 to 300 days (Mueller, 2004). o Some dogs, particularly herding breeds such as Collies, Shetland Sheepdogs, Border Collies, Australian Shepherds, and Old English Sheepdogs, may have mutations in their MDR1 genes and thus have increased risk of avermectin/milbemycin toxicity. The escalating dose regimen should be discontinued if any of the following signs are observed: mydriasis, mild salivation, significant changes in behavior, ataxia, or seizure. Practitioners can determine whether a dog has the MDR1 mutation by sending a cheek scraping to the Washington State University at Pullman College of Veterinary Medicine Veterinary Clinical Pharmacology Lab for analysis (http://www.vetmed.wsu.edu/depts-VCPL/test.aspx). o Moxidectin/imidacloprid topical (Advantage Multi®) is marketed in Europe under the trade name Advocate® and carries a label claim in Europe for treatment of D. canis infestation (Heine et al, 2005).
* No products are labeled for demodicosis in cats. * Lime sulfur dips have been reported effective. Dips should be performed weekly for 6 weeks with 3.1% solution (4 ounces per gallon of water). * Ivermectin has been used once weekly at 0.3 mg/kg orally for four consecutive weeks. Side effects may occur. * Amitraz has been used in cats at a 0.0125 to 0.025% solution every 5 to 7 days for 4 to 6 weeks. Side effects may occur.
(Go to top) Control and Prevention
* Metaflumizone/amitraz (ProMeris® for dogs) is a monthly product approved for the control of Demodex spp. that can cause demodectic mange. * For intact female dogs that develop generalized demodicosis, spaying is recommended because they may experience relapse of disease in subsequent heat cycles. * The development of demodecosis was long believed to have a genetic predisposition, and as a result, some veterinarians discourage breeding affected animals. However, the hereditary nature of demodecosis has not been clearly demonstrated.
(Go to top) Public Health Considerations
* Demodex mites are host-adapted; there is no zoonotic potential in either canine or feline demodicosis.

If I have my mange mits right(bad spelling ahead), demodectic mange is gentic, and brought on by a poor immune system. Scarcoptic mange is a highly contagious mite, known as scabies in humans. If I am wrong, someone please correct me.
The question is what kind of mange does your dog have. If demodectic, then depending on your health guarantee, the breeder should do something. It really depends on the health guarantee you go from the breeder, if it only guarantees life threatning, then you are probably out of luck.
It is also not expensive to treat, but if demodectic, it is a lifetime problem, and can rise up anytime. I would consult another vet.
ok thanks.but there was no health guarantee,im just saying that there was a physical examination when i purchased him.i bought the dog as is based on only his examination,really i guess a vet wouldnt beable to tell if the dog is going to have the mange later.i ask the breeder for the money back and he told me because there was no health guarentee at time of purchase,i was out of luck.is there anything i can do on this situation or am i pretty much screwed out of my money.
In reality, you are not "screwed" out of your money. You bought the pup as is.If the breeder told you that up front,then it was your choice. You have never said what type of mange it has. Demodectic mange is very treatable. If it is localized it could heal itself with no treatment. If it is generalized it can still be kept under control with the right treatment.
I is important to know what 'type' of mange it has. Treatments and causes can differ. Since the dog was purchased by you with no health guarantee in place, then you have no real grounds for a refund. Have you asked the breeder if they will take the puppy back and refund the money? To ask for a refund and keep the puppy is unreasonable in some cases. $500 is cheap for a Yorkshire Terrier IMO as well. Was the puppy missing any hair when you bought it?
OK treat the mange and then go to a health food store and get some organic milled flax... it's a yellowish powder, and feed that to your pup and in 6 weeks you won't believe the coat! Keeps my fawn Doberman's coat sleek and beautiful, with no alopecia or pustules.
Once the mange is treated, it is important to fortify the animal's immune system to prevent future issues. The dog is much more susceptible to future outbreaks if their immune system is still weakened. These supplements have a longstanding history of both treating and preventing all forms of mange.
