If your Jack Russell Terrier is exhibiting the above symptoms, make an appointment with your veterinarian. Your veterinarian will do a complete physical examination which may include bloodwork, urinalysis, and biochemistry profile. The reason for these initial tests is to check for any other conditions which your dog may have. The veterinarian may also examine your dog’s ears to check for any infection. He may also opt to do some skin tests, which are procedures such as swabs, plucks and scrapes that can possibly determine the cause of the skin irritation. A very small piece of the inflamed skin may be sent off to the laboratory to be tested; this is called a biopsy and can rule out other causes of skin disease.
Allergy testing including specific blood tests and intradermal allergy skin testing may be performed.
Your veterinarian will ask you many questions pertaining to your dog’s lifestyle. The medical professional will gather information about your dog’s diet, daily routines, whether he is mostly inside or mostly outside, the plants in which you have growing within your home as well as on your property, how long he has been suffering from the allergies, and if they just flare-up on occasion or if he has had the skin condition or other symptoms for some time. All this information will help the veterinarian begin to decipher what may be causing the atopic dermatitis.
Oftentimes, the veterinarian chooses to rule out specific food allergies using an elimination diet trial. Your veterinarian will give you specific instructions on how to perform this elimination trial; this is usually accomplished by only feeding your dog specific ingredients and halting all bones, treats, table food, or any flavored medication. Your veterinarian will also suggest the type of dog food to feed him for 8-12 weeks. For most, a hydrolysed diet is prescribed. After this time, you will introduce one food at a time and check for a reaction.
Usually after the elimination diet, and after a specific food is ruled out, the veterinarian will perform allergy testing. However, the veterinarian may have previously performed the skin test during the initial visit. The decisions made by your veterinarian will vary from dog to dog and symptom to symptom. Atopic dermatitis can be effectively diagnosed; however, it does take time and patience to determine precisely what your Jack Russell Terrier is allergic to.
