At the Clinic I work at we charge $23.for the bath and amitraz dip used in treating demodectic mange and if we do the ivermec injection it is $23.50. This type of mange can be control. but if the dog gets stressed it can come back. there is no cure for it. It is best to have a dog with this spayed or neutered. I live in the south maybe things are cheaper here. and it is not contaigous
