As weird as it may sound, the whole concept of allergies is relatively new. Before the 20th century, allergic reactions were scarcely known or recognized. In fact, the term ,,allergy’’ was coined in 1906, by a Viennese pediatrician, Baron Clemens von Pirquet.However, today, over 10% of the population suffers from allergies. As the incidence of allergies has increased in people, there has been a similar increase in allergies in dogs.An allergy can be defined as a state of over-reactivity or hypersensitivity of the immune system to a particular substance. The substances that hold the power to trigger such reactions of the immune system are called allergens. The symptoms of allergies differ, depending on the place where the allergic reaction occurs:
- The dog’s skin – localized or generalized itchiness and skin inflammation or irritation
- The lining of the airways – coughing, sneezing, wheezing and discharge from the nose and eyes.
- The lining of the gastrointestinal tract – vomiting and diarrhea.
- Skin allergies
- Contact allergies
- Pyrethrins found in flea collars
- Pesticide used on lawns
- Certain types of grasses
- Certain types of materials, such as wool and synthetic.
- Atopy
- Seasonal
- Non-seasonal.
- Licking/biting of the paws (usually associated with non-seasonal atopy)
- Licking/biting of the flanks (usually associated with seasonal atopy)
- Anti-inflammatory drugs – antihistamines and corticosteroids
- Shampoos – to sooth the irritated skin and rinse out the allergens from the coat.
- Hyposensitization – to reprogram the dog’s immune system.
