Allergies in Dogs
Attention: It is important to be aware that the signs of allergies may resemble those of other conditions or may even manifest simultaneously. Hence, it is crucial not to try to diagnose your furry friend without the guidance of a veterinarian. Make sure you are ready for your beloved pet to undergo a comprehensive diagnostic assessment to eliminate any other potential causes of itchiness and skin issues. In the event that an allergy is confirmed, it is imperative for your entire family to closely adhere to the advice provided by your vet in order to effectively alleviate your pet's discomfort.
What are Allergies?
Allergies occur when the immune system becomes overly sensitive to a specific substance known as an allergen. These allergens can be found in plants, insects, animals, or certain foods, and are usually proteins. Over time, repeated exposure to the allergen sensitizes the immune system, leading to an exaggerated response upon subsequent exposure. While the immune system is designed to protect the body from harm, allergies cause it to react in a harmful way. Essentially, allergies are an unnecessary immune response to a harmless foreign substance.
The immune reactions involved in allergies are intricate and multifaceted. They typically involve the combination of allergen proteins and antibodies in the bloodstream, which then attach to mast cells. Mast cells are present in various tissues throughout the body. When the allergen and antibody interact with mast cells, these cells release powerful chemicals like histamines, which trigger local inflammation. This inflammation manifests as redness, swelling, and itching, among other signs commonly associated with an allergic reaction.
What are some symptoms of allergies in dogs?
Dogs often show signs of allergies through itchy skin, which can be either in one spot or all over their body. Sometimes, allergies can also affect their digestive system, leading to symptoms like vomiting and diarrhea. Unfortunately, allergies are quite common in dogs.
What are common allergens?
There are countless substances that can trigger allergies. While many are insect, plant, or animal proteins, even small chemical molecules can lead to allergic reactions. Some common allergens include pollens, mold spores, dust mites, skin cells (like pet allergies in humans), insect proteins like flea saliva, and certain medications.
