Dog Allergy Symptoms: How to Spot, Soothe, and Prevent Flare-Ups

Just like humans, dogs can suffer from allergies. Triggers may include food ingredients, environmental allergens (pollen, dust mites, mold), flea bites, or contact irritants. Recognizing the early signs of dog allergies helps you act fast, keep your pup comfortable, and work effectively with your veterinarian.

Common Signs of Dog Allergies

Skin irritation & itching: Excessive scratching, chewing, or rubbing; red or inflamed skin; hot spots; hair loss. Persistent scratching can lead to secondary infections—see your vet if skin looks raw or oozy.
Frequent ear issues: Head shaking, scratching, odor, debris, or recurrent ear infections—often linked to environmental or food allergens.
Sneezing & runny nose: Seasonal pollen, dust, or mold exposure can cause sneezing, nasal discharge, coughing, or wheezing.
Watery, red eyes (conjunctivitis): Excess tearing, redness, or discharge may indicate ocular irritation from allergens.
Digestive upset: Food allergies or intolerances can show up as vomiting, diarrhea, gas, or abdominal discomfort. Work with your vet on elimination diets or testing.
Hives or swelling (urgent): Raised welts or facial swelling require immediate veterinary care.
Paw licking or chewing: Often tied to seasonal or contact allergens the dog has walked on, or to food sensitivities.
Red or irritated skin patches: Rashes or hot spots—especially in areas the dog can scratch or chew.
Behavior changes: Irritability, restlessness, or anxiety from chronic itch or discomfort.

How to Help Your Itchy Dog

See your veterinarian: Rule out parasites, infections, or other conditions. Your vet may suggest skin or blood testing, diet trials, or targeted therapies.
Reduce exposure: Rinse paws and belly after walks, bathe with a gentle hypoallergenic shampoo, wash bedding weekly, and use HEPA filtration.
Support skin & immune health: Many pet parents use omega-rich nutrition and simple-ingredient supplements as part of a wellness plan. Explore Hemp Well Immunity Dog Chews for everyday immune support.
Soothe seasonal discomfort: During high-pollen periods, keep windows closed and wipe down after outdoor play. Ask your vet about additional options if flare-ups persist.
