For demodectic mange, properly performed deep skin scrapings generally allow the veterinarian to identify the microscopic mites. Acetate tape impression with squeezing has recently found to be a more sensitive method to identify mites. It was originally thought that because the mite is a normal inhabitant of the dog's skin, the presence of the mites does not conclusively mean the dog suffers from<unk> . Recent research, however, found that the demodex mite is rarely found on clinically normal dogs, meaning that the presence of any number of mites in a sample is very likely to be significant. In breeds such as the West Highland White Terrier, relatively minor skin irritation which would otherwise be considered allergy should be carefully scraped because of the predilection of these dogs to demodectic mange. Skin scrapings may be used to follow the progress of treatment in demodectic mange. Alternatively, plasma levels of zinc and copper have been seen to be decreased in dogs suffering with<unk> . This may be due to inflammation involved in the immune response of<unk>  which can lead to oxidative stress, resulting in dogs suffering from<unk>  to exhibit higher levels of antioxidant productivity. The catalases involved in the antioxidant pathway require the trace minerals zinc and copper. Dogs with<unk>  show a decrease in plasma copper and zinc levels due to the increased demand for antioxidant activity. Therefore, this may be considered as a potential marker for<unk> .
