Dog Allergies Explained: Common Triggers and Veterinary Solutions

September 22, 2025

Few things frustrate dog owners more than watching a pup scratch, lick, or chew nonstop. At Luv-N-Care Animal Hospital of Windermere, our veterinarians frequently diagnose and treat dog allergies in families across Windermere, FL. Allergies make life uncomfortable for dogs but, with proper care, they can be managed successfully.

Causes of Allergies in Dogs

Common allergy triggers include:

  • Environmental allergens: pollen, mold, dust mites, grasses
  • Flea bites: particularly flea allergy dermatitis
  • Food sensitivities: common culprits are chicken, beef, or grains
  • Contact irritants: cleaning chemicals, fabrics, or shampoos

Warm Florida weather means fleas and environmental allergens are active nearly year-round, making allergies especially common here.

This is also something to be aware of when traveling, as Fido may come across pollen or other allergens he isn’t used to. Click here to read our blog on travelling with pets. 

Dog Allergy Symptoms

Dog allergy symptoms vary but typically include:

  • Persistent itching and scratching
  • Red or inflamed skin
  • Frequent ear infections
  • Watery eyes or sneezing
  • Gastrointestinal upset (if food-related)
  • Hot spots or bald patches from licking

If your pooch is constantly uncomfortable, allergies may be to blame. Purdue College of Veterinary Medicine has some helpful information about pet allergies on their website here. Pet MD also has a post on skin allergies in dogs, which you can find here.

Diagnosing Dog Allergies

At our vet clinic, diagnosis options will vary, depending on the type of allergy being diagnosed. Some standard options may involve:

  • Ruling out parasites and infections
  • Trial food elimination diets
  • Blood or skin testing for environmental allergens

Correct diagnosis can help your vet narrow down what will be the most effective treatment, and  help get your pet relief.

Treating Dog Allergies

Treatment depends on the cause and may include:

  • Flea prevention for flea-related allergies
  • Hypoallergenic diets for food sensitivities
  • Medications to reduce itching and inflammation
  • Regular baths with medicated shampoos to remove allergens
  • Allergen immunotherapy for long-term management

Many dogs require a combination of treatments for best results.

Fun Fact: Some Dogs Are Allergic to People
