This step is very important. Take a trimmer and clip all the hair over the hotspot and in a small region around it. Mark the hotspot using a color pen. This helps to find out whether the dog hotspot is growing in size or reducing. It can then be used as a criteria to decide whether it is necessary to go to the veterinary doctor. Why is it necessary to cut the hair around a hotspot ? That is because hotspot is a dermatitis ( a kind of infection ) and it often becomes worse when it grows under hair cover.
