Just like humans, dogs are also prone to allergies. Allergies manifest in your dog based on his reaction to certain allergens. Among the most common types of allergens are flea saliva, inhaled substances such as pollen and dust, and certain ingredients in their dog food. To help you understand each of these allergens and how it can unfavourably affect your dog’s behaviour and health, please refer to the list below:

1. Allergy caused by fleas - the most common allergen that your dog can encounter is flea allergy dermatitis, which is a condition of hypersensitivity to the protein in flea saliva. It’s most commonly diagnosed after the age of 2 among dogs. This kind of allergen is considered most severe from midsummer through the autumn season and would require veterinary care. In warmer climates, it can be a year-round plague.

Flea allergic dogs will scratch and bite themselves, with most of the intense itching and biting occurring near the base of the tail. If your dog is experiencing this kind of allergy, take him to the vet immediately for proper medication. It is also advised to do a flea control in your home as well as on surrounding areas. Finally, regular grooming, brushing, and thorough bathing for your dog are essential for the prevention of flea allergy.

2. Allergy caused by inhaled substances - certain substances like dust, pollen and danders that are inhaled by your dog can cause them to have an allergic reaction. Dogs that are allergic to these inhalants rub their faces, muzzles and eyes, scratch their armpits and ears, bite their feet and legs, and may develop red and swollen patches on their skin. It is important for you to remember that your dog may have some allergic reaction to some elements in his environment, like carpet fibres, bedding, cleaning agents, plastics, or fertilizers. So be very aware on these aspects. Make sure that you avoid letting them inhale substances that may come from such elements.

3. Allergy caused by ingredients in their food - similar to inhalant allergies, allergies in food can also cause itching, which can make the dog scratch, rub, chew, bite, and lick his skin. The most common ingredients that can cause allergies in dogs are beef, pork, chicken, milk, eggs, fish, corn, soy, and preservatives. So be conscious in giving commercially prepared food to your dogs. As much as possible, read the label of the dog food to know its content and nutritional value. Ask your vet what types of dog food is best for the health of your dog and refrain from buying cheap dog food products because it is most likely that it contains extenders that may harm your dog’s digestive system.
