It often makes sense to create a list of possible causes, based on the evident symptoms, changes to the skin and the animal’s background. Not all itchiness is caused by fleas, for example, although fleas are very often part of the problem and flea treatment often comprises part of the therapy.
Causes can also include food allergies, fungal infections, bacteria, foreign bodies, neurological disorders, hormonal imbalances and tumours. Sometimes several factors can be causing problems at the same time, for example if the skin has been previously damaged by a fungal infection, and bacteria subsequently also infect the area
Treating chronic cases
A systematic approach is especially important in difficult or chronic cases. You should not become disheartened too prematurely as a dog may take some time to respond to treatment. In Germany, the Chamber of Veterinary Surgeons for each federal state can provide pet owners with a list of vets who are specialised in the diagnosis and treatment of skin conditions (dermatology).
