Vet Q&A: Recognizing Dog Allergy Symptoms

Introduction
It starts with a scratch, then a lick, then another. Before you know it, your dog’s skin looks red and irritated. Allergies in dogs are more common than many owners realize, and they can show up in subtle ways. In this Vet Q&A, we break down the most common signs, causes, and what to do if you suspect your pup might be allergic.

Q: What are dog allergies?
Allergies happen when a dog’s immune system reacts too strongly to everyday substances — things like pollen, dust mites, food proteins, or even flea bites. These “overreactions” cause inflammation that often shows up on the skin, ears, or digestive system.

Q: What symptoms should I watch for?
Dogs can’t tell us they’re itchy, but their behavior speaks volumes. Look for:
– Persistent scratching, licking, or chewing (especially paws, ears, and belly)
– Red or irritated skin and small scabs
– Repeated ear infections or head shaking
– Hair loss or thinning patches
– Sneezing or watery eyes during certain seasons
– Upset stomach, vomiting, or loose stool (especially with food allergies)
Some dogs even develop darkened skin or a strong odor due to secondary infections.

Q: How do vets diagnose allergies?
Your veterinarian will first rule out other causes like fleas, mites, or skin infections. From there, they might suggest:
– Elimination diet trials using hypoallergenic food like Hill’s Prescription Diet z/d or Royal Canin Hypoallergenic to test for food sensitivities
– Blood or skin testing to identify environmental allergens such as pollen, mold, or dust mites
– Detailed lifestyle review, including diet, environment, and seasonal changes, to pinpoint patterns

Q: How are dog allergies treated?
While allergies can’t be “cured,” they can be managed effectively with a tailored plan. Treatment often includes:
– Medications like Apoquel or Cytopoint to control itching
– Medicated baths with soothing shampoos such as Douxo S3 Calm
– Flea prevention (since flea bites can trigger major reactions)
– Diet changes to hypoallergenic or limited-ingredient formulas
– Allergy shots (immunotherapy) for long-term desensitization if specific allergens are identified
Vets may also recommend omega-3 supplements to support skin health and reduce inflammation.

Q: When should I see a vet?
If your dog is constantly scratching, has recurring ear infections, or develops hair loss or red patches, it’s time for a checkup. Severe cases with swelling, hives, or breathing trouble require immediate veterinary attention.

Conclusion and CTA
Allergies can make life uncomfortable for your dog, but early recognition makes a world of difference. With the right diagnosis and care plan, most dogs find lasting relief. For medical concerns, consult your veterinarian.
