This study focuses on treating allergic rhinitis caused by dog allergies. The main treatment being tested is Alutard SQ dog, which is given as an injection under the skin. The study aims to determine how well this treatment improves allergy symptoms in people who are allergic to dogs after one year of treatment. Additional medications that may be used during the study include Nasonex nasal spray, Livostin eye drops, and Desloratadine tablets.

The treatment involves receiving injections of Alutard SQ dog, which contains small amounts of dog allergens. These allergens are substances from dogs that cause allergic reactions in some people. During the study, participants may also use other allergy medications to help manage their symptoms. The study will last for approximately one year.

The researchers will measure how well the treatment works by checking changes in nasal symptoms and using a rating scale to assess allergy symptoms when exposed to dog dander. They will also monitor breathing ability and check for any changes in eye symptoms. Throughout the study, doctors will keep track of any side effects that may occur during the treatment.
