When we start diet management of dogs with itchy skin, we advise use of SINGLE PROTEIN DIETS. (SDP) This means we expose the dog to just ONE source of meat protein & preferable a NOVEL protein - one that the dog hasn't had before. For example, we may start with Kangaroo, Salmon or Crocodile, mixed with either regular or sweet potato. That's it! Nothing else! Boring isn't it but tha'ts the best way to start assisting skin management. Treats can be in the form of eg roo tail. NOTHING ELSE except for a Precription Diet of biscuits if required e.g Hills Derm Defense.
To add Herbal Medicine to our Management Plan, we examine the WHOLE DOG i.e. we examine all body systems to decide which systems need treating. We often need to address the Immune System, the Gastrointestinal System as well as the Integument (skin). Treatments will thus vary from animal to animal - there is not a "One Cure Suits All".
