Which common symptom might suggest that a pet is experiencing an allergy?

Itching and scratching are classic symptoms that often indicate a pet is experiencing an allergy. Allergies in pets can result from various triggers, including environmental factors (like pollen or dust mites), food ingredients, or flea bites. When a pet's immune system reacts to these allergens, it can lead to skin irritation causing the pet to scratch, bite, or lick affected areas.

This behavior is not only an indicator of discomfort but can also lead to other skin issues such as infections if the skin barrier is compromised. Identifying itching and scratching as a sign of allergies is crucial for prompt and effective treatment, which may include antihistamines, corticosteroids, or changes in diet, depending on the underlying cause.

Other symptoms mentioned, such as elevated body temperature and lethargy without appetite, may indicate various health issues but are not specific to allergies. Head shaking can also be a sign of different conditions, such as ear problems, rather than allergies as a primary concern. Thus, recognizing itching and scratching as a sign of allergies is key to addressing potential health issues in pets.
