How Is a Skin Scraping Done in Dogs?

A skin scraping is performed by collecting a sample of skin cells with the use of a scalpel blade. The blade is used to gently scrape layers of the skin, usually until a small amount of blood is seen, so that your veterinarian can gather cells deep in the skin. This is important, especially if parasites are suspected, since they often live deep in the skin. The skin cell sample is placed on a microscope slide, mixed with oil and evaluated under a microscope. Most often, results are available within 30 minutes. Sometimes, the veterinarian may need a second opinion and will submit the skin scraping sample to an outside laboratory. Results may take two to four days.
