Common Disease Name:
Mange, scabies
Medical Term for Disease:
Sarcoptic mange
Species Affected by Disease:
Dogs
Age Animal Usually Affected:
Any
Commonly Affected Breeds:
Any
Sex Usually Affected:
Any
Disease Symptoms:
Intense itching in areas with thin
hair such as belly, chest, elbows, hocks, ear margins, and around
eyes. There will be skin crusts and scales, evidence of self trauma,
and sometimes skin infection. Poor response to steroids is a sign that it might
be mites. In multiple dog households, more than one dog usually shows symptoms.
Method(s) of Diagnosis:
Skin scraping may find mature
adults and eggs, but they can be difficult to find. Any dog with clinical signs
suggestive of sarcoptic mange should be treated for scabies, even if
skin scrape results are negative. Sarcoptic mange can resemble
pruritic impetigo in young puppies. Always consider sarcoptic mange as a
possible cause of pruritus in an allergic dog that is no longer responding to
corticosteroid therapy.
Disease Causes:
Infestation with the mite,
Sarcoptes scabiei var. canis.
Treatment:
Baths and dips. Prescription Ivermectin should be used with extreme
caution in collies, Shetland sheepdogs, old English sheepdogs, Australian
shepherds, and their crossbreeds because Ivermectin toxicity is more likely to
occur in herding-type breeds.
Prognosis:
Excellent. All dogs in the
household should be treated. Response to treatment should be seen within 2
weeks. If none is seen, make sure the treatment protocol is being followed.
Complications:
Can be passed to other animals and
to humans. People that come in close contact with an affected dog may develop an
itchy, bumpy rash on their arms, chest, or abdomen. Human lesions are usually
transient and should resolve spontaneously after the affected dogs have been
treated. If the lesions on people persist, advice from a human dermatologist
should be sought.
Prevention:
Once a dog is diagnosed, he should
be isolated until the disease is under control. Also, bed linens should be
cleaned to prevent the spread to humans.
Medicines Used for Treatment of Disease:
Anti-seborrheic
shampoo bath followed by total body treatment with 2% lime sulfur solution
(LymDip), Mercaptomethyl phtalimide (Paramite) dip or Ivermectin orally or by
injection (This is extra label use and is not approved by the FDA for treatment
of sarcoptic mange) Antibiotics as needed for secondary bacterial infection and
short-term steroids if needed for severe itching.
Helpful Products:
"Revolution @” will help prevent
infestation in multiple dog households. All dogs exposed should d be treated
