Ask Dr. Claire

My beagle has a bad rash all over her body and scratches herself all the time. Do you have any thoughts? We have tried diets and creams etc.

Itchy skin is really just a symptom and can be the result of many underlying causes. In this case, we really need to find the cause of the itchy skin so that we can treat your dog’s problem (not just the symptom). This will help us reach the best treatment plan too.

Beagles are a breed particularly predisposed to skin allergies. 

Some of the underlying causes of itchy skin might be:

• Allergies– environmental pollens, food, fleas. We know that when humans have allergies to pollens etc they react by sneezing or getting watery eyes. In dogs, the common reaction to an allergen is that their skin gets itchy. Allergies causing itchy skin include food, fleas and environmental pollens- either breathed in or physically touched. Although you’ve touched on diet – it could be a protein or other carbohydrate that is the problem, so ruling out food allergy can be difficult if not done properly.  
• Mites– demodex or sarcoptes. Your local vet needs to do some simple tests to diagnose these, a few skin scrapes are performed (no anaesthetic needed) and then they look under the microscope, searching for the mites.
• Direct irritant- such as a topical cream, weed, wash or insect bite.

A cool bath to remove any allergens and wash in soothing dog oatmeal shampoo would be helpful, and well as a dog leave on conditioner. But, if the itch is escalating he may need some medication to help.
