Allergic dermatitis — Dogs

The story behind the answer

Allergic dermatitis is the correct answer because it literally means “skin inflammation from allergies” (derma = skin, -itis = inflammation). In dogs, it commonly appears as intense itching, redness, irritation, and can progress to hair loss, hot spots, or sores from scratching and licking. Triggers include flea bites (flea allergy dermatitis), food proteins, and environmental allergens like pollen or dust mites. Paws, ears, belly, and armpits are frequent trouble spots.

Remember: itchy dog + red, irritated skin = think allergy. Unlike the other choices (a place, a behavior, or a group of puppies), allergic dermatitis is a medical skin condition. Management often involves flea control, hypoallergenic diets or trials, medicated baths, and vet-prescribed therapies to calm inflammation and prevent infections.
