There are a number of medical causes of itchniness in a dog, including ectoparasites, infections of the skin (fungal, bacterial, viral), metabolic disorders, and even allergies. Sometimes allergies are to ingredients in the dog's food; sometimes they are due to irritants in the enviroment, like fabric freshners, laundry detergents, floor and carpet cleaning products. You should have your dog evaluated by your veterinarian. S/he will want to do a complete physical exam and may also recommend taking skin/hair samples for diagnostics purposes.
