Atopy in dogs

Atopy in dogs, also known as atopic dermatitis or allergic dermatitis, is a common allergic skin
condition caused by an allergic reaction to environmental allergens such as pollen, dust mites,
mold spores, or certain grasses. It typically affects dogs between 1 to 3 years of age but can
occur at any age.
Signs of Atopy in Dogs:
– Itching and scratching, often intense
– Frequent licking or chewing of paws, face, ears, or groin
– Redness, inflammation, or rash on the skin
– Ear infections or recurrent otitis
– Hair loss or thinning in affected areas
– Skin infections due to scratching and irritation
Causes:
– Allergic reaction to environmental allergens (inhalant or contact allergens)
– Usually seasonal, but can be year-round depending on exposure
Diagnosis:
– Based on clinical signs and history
– Skin scrapings, cultures, or allergy testing (intracutaneous or blood tests) can help confirm
allergies
– Food trials with Novel protein sources or Prescription hydrolyzed diets to rule out food allergies
as a cause of skin issues.
Management and Treatment:
– Allergen avoidance:Reducing exposure is ideal but often difficult and imparctical
– Medications:
– Antihistamines (e.g., diphenhydramine) don’t work for Atopy.
– Corticosteroids for short-term relief and can help in the initial phase of the treatment.
– Apoquel or Cytopoint, newer medications targeting allergic itch. These medications have
fewer side effects , are well tolerated and can be used on a long term basis if effective.
– Medicated baths or shampoos: To soothe skin and reduce allergens
– Dietary management:** Sometimes food allergies coexist; a hypoallergenic diet may help
– Immunotherapy:** Allergy shots tailored to the dog’s specific allergens can provide long-term
relief in some cases.
Management
– Regular bathing and grooming
– Keeping the environment clean and dust-free
– Monitoring and managing seasonal changes
