@krunzer:
Sounds like Revolution to me also, but is that a prescribed medication for Sarcoptic mange?
Selamectin is an ivermectin derivative recently marketed in the dog for the control of fleas, ticks, heartworm, ear mites and sarcoptic mange mites. Normal monthly use of this product should prevent a sarcoptic mange problem but to clear an actual infection studies show an extra dose is usually needed after 2 weeks for reliable results.

Of course, you could use ivermectin off label:
IVERMECTIN - This is one of the most effective treatments against Sarcoptes scabei yet is off-label as far as the FDA is concerned. There are several protocols due to the very long activity of this drug in the body. Typically an injection is given either weekly or every two weeks in 1-4 doses. In most cases this treatment is safe and effective but some individuals have a mutation which makes ivermectin very toxic at the doses used to kill mites.
I would think for a Basenji it would be safe, Not for collie type dogs, however…..
