7 Common Signs of Allergies in Dogs

1. Excessive Itching & Scratching

If your dog is constantly scratching or biting their skin, allergies might be the cause. Fleas, food sensitivities, or environmental triggers like pollen can all lead to itchy skin.

2. Red, Inflamed Skin 🌸

Look for hot spots, redness, or rashes on your pup’s belly, paws, or ears. These are often signs of allergic reactions.

3. Chronic Ear Infections 👂

Recurring ear infections, shaking the head, or smelly ears may indicate a food or environmental allergy.

4. Watery Eyes & Runny Nose 👀

Like us, dogs can get watery eyes, sneezing fits, and even nasal discharge when allergies strike.

5. Constant Paw Licking 🐾

If your dog licks their paws obsessively, it may be their way of soothing itchy, irritated skin caused by allergens.

6. Digestive Problems 🍗

Diarrhea, gas, or frequent vomiting may be linked to food allergies. Common culprits include beef, chicken, dairy, and grains.

7. Hair Loss or Bald Patches ✂️

Allergy-related scratching and chewing can lead to bald spots, scabs, or thinning fur over time.

What You Can Do to Help 🐕

✅ See Your Vet – Always the first step. Your vet can recommend tests and treatment.
✅ Switch to Hypoallergenic Food – Limited-ingredient or grain-free diets often help.
✅ Regular Baths – Using gentle, allergy-friendly shampoos can ease skin irritation.
✅ Flea & Tick Prevention – Parasites are a major allergy trigger, so stay protected.
✅ Track Symptoms – Use the 30-Day Puppy Journal to record scratching, diet, and health changes. This makes vet visits much more effective.

Allergies in dogs are more common than most pet parents realize — but with the right care and attention, you can help your pup live a happy, itch-free life.
