In summary, keep in mind that any dog with skin problems or whose skin and coat are not in optimal health needs attention because that dog surely does not feel well. Be patient with your veterinarian because each category of "Dermatitis" must be evaluated, categories need to be ruled out, and a final diagnosis needs to be established BEFORE proper, effective treatment begins. Expect laboratory work, skin scrapings and blood tests to be required to reach that diagnosis.
If your dog is suffering from Chronic Dermatitis, all is not hopeless. Be persistent in trying to identify the cause and then pursuing a treatment. And do not be bashful about requesting referral to a specialist in veterinary dermatology. These experts work with severely affected patients on a daily basis and can be an excellent resource for assistance to those poor dogs that seem incessantly to itch-and-scratch-bite-and-lick. Resolving these cases invariably puts a smile on the veterinarian’s face, the pet owners face, AND the dog’s!
