Signs That Point to a Skin Allergy
- Frequent licking or chewing of the paws, staining the fur reddish-brown
- Ear scratching, head shaking or repeated ear infections
- Red skin or a rash on the belly, armpits and groin
- Seasonal or year-round itching
- Skin infections that keep returning in the same spots after treatment
The Main Causes in Dogs
In Bangkok's hot, humid climate, three groups of causes are most common: flea allergy dermatitis, where even a few bites can trigger intense itching; environmental allergy (atopy) to dust mites and pollens; and food allergy, which often combines itching with digestive issues.
Why Self-Medicating Makes Things Worse
Allergic itching, bacterial and fungal infections, and mange can look very similar from the outside. Using medicated shampoos or medicines bought without a diagnosis often lets the condition spread and become harder to treat — as we described in why early treatment matters.
How Veterinarians Find the Cause
Allergy diagnosis is a systematic process of elimination: skin exams and sampling to rule out infection and parasites first, strict flea control, and — if food allergy is suspected — a controlled elimination diet for a period, before concluding it is environmental allergy, which needs a long-term management plan.
Long-Term Care That Works
Most skin allergies can be controlled well once the cause is known. Bathing with vet-recommended products, consistent flea prevention and regular follow-up greatly reduce flare-ups.
