How is allergy expressed in dogs? - in detail
Allergies in dogs can manifest in various ways, with symptoms often affecting the skin, ears, and gastrointestinal tract. One of the most common signs of an allergic reaction in dogs is itching, which can be localized or generalized. This persistent scratching can lead to hair loss, redness, and secondary skin infections.
Food allergies are often associated with gastrointestinal symptoms such as vomiting and diarrhea. These issues may be accompanied by excessive gas or abdominal pain. In some cases, the dog's coat may become dull or dry due to nutrient malabsorption related to the allergy.
Ear infections are another common symptom of allergies in dogs. Chronic ear problems, characterized by redness, swelling, and a foul odor, can be an indicator of an underlying allergic issue. The dog may also exhibit excessive scratching or head shaking as a result of the discomfort.
In addition to these primary symptoms, allergies can have systemic effects on dogs. Some dogs may develop asthma-like symptoms, such as coughing and wheezing, due to inhalant allergens. Allergies can also affect a dog's eyes, causing redness, discharge, or excessive tearing.
It is important for owners to be aware of these signs and seek veterinary care promptly if they suspect their dog has an allergy. Early diagnosis and treatment can help alleviate the dog's discomfort and prevent complications such as secondary infections or chronic disease development.
