Skin parasites such as fleas are the number one cause of itching in dogs, and some dogs are so sensitive to a flea's bite that only one bite can st their skin off. If the flea prevention you are using is over the counter there is a good chance it is not working on the fleas. You can try a prescription strength medication one month from your last dose. In the meantime you should try the following to help Kilo with his skin; Bath with soothing or gentle shampoo Treating your home for fleas using an indoor flea spray Consider switching to a food which promotes skin health Add fish oils and vitamin E to his diet Cutaneo Trubenefits and omega benefits http://www.vrshealth.com/canine-products/?petcoach=1977955
