Allergies in dogs: the main types and methods of control
Allergies affect not only people, but also four-legged friends. The only difference is that they are not able to say this, so it is important for any owner to know how to determine the disease at an early stage. Dog allergies have similar symptoms.
Consider existing allergens, symptoms and treatment, adjusted for the type of allergy.
Causes of occurrence
The causative agents of an allergic reaction are antigens – substances that are perceived by the body as foreign and cause an immune response.
Please note that not every immune response is expressed as an allergy. This reaction causes only a specific type of antigen – allergens.
Types of Allergens
The causes of the disease are classified by type of allergy:
Medicinal Intolerance to a number of drugs, including:
Infectious. Called by bacteria, fungi, viruses and helminths.
Autoimmune. A rare type of disease characterized by an immune response to its own cell tissue.
Food. The most common type associated with intolerance to certain products. It usually develops after 2 years of age.
Contact (atopy). Reactions are caused by the contact of the skin with grass, household chemicals, cosmetics and tissues.
Insect (flea dermatitis). An allergen is a substance injected by blood-sucking insects.
Respiratory It is observed when inhaling pollen, dust, household chemicals, mold and other substances.
I would like to pay special attention to food allergies, most often provoked by protein compounds and additives in industrial feeds.
Common food allergens
artificial additives, dyes and preservatives used in dry feed;
fish and fish oil;
chicken containing a large number of antibiotics used for the rapid growth of chickens;

Dog allergies occur at any age and depend on the following factors:
The main allergies include:
German shepherd dogs

Signs of the disease can not always be realistically noticed in a timely manner, since the thick coat of the animal makes it difficult to see.

funded, formed after a long time, in some cases exceeding several weeks.
Common allergy symptoms include:
increased lacrimation and discharge from the sinuses of a transparent color;
the occurrence of edema, rash and scratching;

a stool disorder characterized by frequent emptying and diarrhea.

redness and rash on the face;
anaphylactic shock (anaphylaxis).
Infectious. It manifests itself in an increased reaction of the body to the pathogen. Such pets are prone to repeated illnesses with a more severe course.
Autoimmune. It is expressed:
the occurrence of immune dermatitis (bullous pemphigoid, cutaneous vasculitis);
damage to the mucous membranes and skin (toxic epidermal necrolysis, leaf-shaped and erythematous pemphigus);
inflammatory processes (erythema multiforme);
connective tissue diseases (lupus erythematosus).
Food. When responding to foods, it is noted:
dandruff and dry skin;
skin redness and rash;
the appearance of bald spots and falling out hair;
vomiting and bowel upset;
inflammation of the tongue and gums, accompanied by an unusual smell from the mouth.
Contact. Dog allergies are characterized by:
the appearance of eczema between the fingers;

redness on the paw pads.
Insect. When examining an animal, it is found:
the presence of parasites;
exfoliation of the skin or the presence of white crusts;
