Presenting Signs – Canine

The following can be characterised as symptoms of dog allergy:

Dermatological Signs

These signs are compatible with canine atopic dermatitis (CAD) or adverse food reaction:

  • Pruritus is the most common sign in over 95% of cases
  • Recurrent Otitis Externa
  • Erythema
  • Alopecia
  • Recurrent Staphylococcal pyoderma

Gastrointestinal Signs

Adverse food reactions (food allergies) in dogs manifests as a range of clinical signs from the minor:

  • tenesemus, flatulence, occasional borborygmy, soft stools/mucus

To the more severe:

  • vomiting, diarrhoea, gastroenteritis, colitis, weight loss

Dermatological and gastrointestinal signs frequently co-exist, hence the importance of selecting both Environmental and Food tests.

Behavioural Signs

  • Paw Chewing
  • Face Rubbing
  • Self-induced trauma

Atopic dermatitis in dogs

A genetically predisposed inflammatory and pruritic allergic skin disease with characteristic clinical features associated with IgE antibodies most commonly directed against environmental allergens.

Atopic-like dermatitis in dogs

An inflammatory and pruritic skin disease with clinical features identical to those seen in canine atopic dermatitis in which an IgE response to environmental allergens cannot be demonstrated.

Accurate diagnosis requires a complete detailed history, full clinical examination, evaluation of differential diagnoses and allergy testing
