I currently use a collar with Amitraz in it. Can ProMeris for dogs be used on dogs wearing Amitraz collars?
While we recommend the use of ProMeris for dogs without the Amitraz collar, we have conducted a safety study and found no adverse events were observed when these products were used simultaneously. Because Amitraz collars are commonly used to kill ticks on dogs and ProMeris for dogs also kills ticks, one would not expect the use of these collars to provide more tick control than the use of ProMeris for dogs by itself. Dogs wearing an Amitraz collar can be transitioned to ProMeris for dogs by removing the collar and then applying ProMeris for dogs.
