Numbers that are within the inner fences are considered reasonable.'' The whiskers go to the farthest numbers that are within the fences. Then we go out a distance of 1.5(IQR) again from the inner fences, and draw the outer fences. These are more for show and to make the neighbors jealous.
Why Do Hot Spots Occur? Anything that irritates the skin and causes a dog to scratch or lick himself can start a hot spot. Hot spots can be caused by allergic reactions, insect, mite or flea bites, poor grooming, underlying ear or skin infections and constant licking and chewing prompted by stress or boredom.
Allergic reactions to some foods, plants, or even the irritants might also result in the discolored skin patches in various areas of the body. These changes can present as the rashes or raised bumps that normally itch or burn. One common allergy that might cause skin black spots on skin is the eczema. Like certain autoimmune diseases, eczema usually triggers an immune reaction that attacks the skin. The condition can lead to scaly patches and the red bumps that ooze or crust over.
