Skin reactions in allergic dogs

Dogs can suffer from allergies, just like humans. Atopy (dermatitis due to the inhalation of allergens) is a disease that affects humans, dogs and cats. It is a hereditary condition that produces hypersensitivity (allergy) to allergens in the environment. The disease affects between 10 and 15% of dogs, but the symptoms are very different from those afflicting humans.

Although the animal is usually between one and three years old when atopy first manifests itself, it can appear at any age. Initially, the condition appears seasonal, but as the animal ages, the allergy tends to worsen and last all year round.

The main sign of atopy is itching in one or more of the following areas:
Head - The animal rubs its head, especially around the ears, muzzle and eyes. Often, he also has a chronic ear infection.
Paws - Dogs suffering from atopy often chew, nibble and lick their paws.
Groin and armpits - The dog may chew, lick, nibble or scratch the skin in the inguinal and armpit areas.

The itching may eventually spread to the whole body. Respiratory symptoms such as sneezing, wheezing and coughing are rare. Left untreated, atopy can produce secondary infections, including bacterial or yeast infections. Infection can exacerbate itching and complicate treatment.

Your veterinarian can diagnose atopy by studying the animal's history and performing a physical examination. If necessary, an allergy test can be performed to confirm the diagnosis and identify the allergenic agents.
