Atopy in Dogs

                         -------------

                      General Information



Atopy is an intensely itchy skin condition caused primarily by

inhaled allergens, such as molds, pollens and dust.

Occasionally atopy results from allergens that are absorbed

through the skin or eaten.  Dogs with atopy are genetically

predisposed to the condition, and certain breeds, such as

Schnauzers, Irish Setters, Boston Terriers, Scottish Terriers,

West Highland White Terriers, Cairn Terriers and Wire-Haired

Terriers, are more commonly affected than other breeds.  Female

dogs are more likely to be affected than males.  Atopy usually

first occurs at 1-3 years of age.



Atopy may be seasonal or nonseasonal, but most dogs with atopy

eventually have nonseasonal signs.  About 3/4 of atopic dogs

first develop signs from spring to fall.



Itching is the main sign of atopy.  Chewing, scratching and

bacterial infection damage the skin.  The face, feet and abdomen

are usually the first areas affected.  Besides skin problems,

other signs, such as a runny nose, asthma, cataracts, and

urinary and gastrointestinal disorders, occasionally occur.



                 Important Points in Treatment



1.  Both skin and blood tests are used to identify the cause of

    the allergy.  Your doctor will advise you if either of these

    types of tests are necessary.



2.  Keeping your dog away from the cause of the allergy is not

    always practical or possible.  When the cause is known and

    avoidance is possible, this is the best means of atopy

    control.



3.  Treatment with anti-inflammatory drugs is often the most

    effective means of controlling atopy.  In some dogs, however,

    these drugs become less effective as time passes, and may

    cause undesirable side effects.



4.  Desensitizing injections (allergy shots) may help if

    avoidance or drug therapy is ineffective.  Desensitization,

    however, is not always effective, and continued treatment is

    usually necessary.



5.  Regular bathing and grooming frequently help control atopy.



6.  Treatment recommended for your dog is:





        Notify the Doctor if Any of the Following Occur:



    * Your dog's discomfort is not relieved.



    * Your dog's signs change.



    * Your dog's general health worsens.



    * Your dog's conditions spreads.
