Does My Pet Have Allergies?
Have you ever noticed your dog rubbing their face along the carpet like they’re trying to scrub something off… or your cat chewing at their legs like they’re gnawing on a cob of corn? While it might seem silly at first, these behaviors are often signs of something very real—and very uncomfortable—for your pet: allergies. At PetMed of Key West Veterinary Clinic, we see pets with allergies almost every day. They can show up in many ways, and while there’s no one-size-fits-all solution, working with your veterinarian can make a world of difference.
Common Signs of Allergies in Dogs and Cats
Allergies in pets don’t always show up the same way they do in humans. Instead of sneezing or watery eyes (though that can happen too), you may notice:
- Excessive licking or chewing of paws and legs
- Frequent scratching or rubbing their face on furniture
- Ear infections or head shaking
- Hot spots, hair loss, or red, irritated skin
- Red-stained fur from constant licking
- Vomiting or diarrhea (especially with food allergies)
These symptoms can range from mild to severe—and if left untreated, can lead to infections, discomfort, and even long-term skin changes.
The 3 Main Types of Pet Allergies
Our veterinarians group pet allergies into three primary categories:
1. Environmental Allergies (Atopy)
Environmental allergies are caused by pollen, dust mites, mold spores, and grasses. Common symptoms include itching, red skin, sneezing, watery eyes, and licking paws.
2. Food Allergies
Food related allergies are often caused by proteins like chicken, beef, dairy, or grains. Common symptoms such as vomiting, diarrhea, ear infections, and itchy skin may indicate an issue.
3. Flea Allergy Dermatitis
A severe allergic reaction to flea saliva—even one flea bite can cause weeks of intense itching. You might notice symptoms such as relentless scratching, hot spots, scabbing, and tail-base irritation.
So What Can You Do About It?
There’s no permanent cure for pet allergies—but there are many ways to manage them. With the help of your veterinarian, you can find the combination of treatments that keeps your pet happy, comfortable, and itch-free.
Environmental Control
- Frequent bathing with hypoallergenic or oatmeal shampoos
- Wipe your pet’s paws and coat after walks
- Use air purifiers and regularly clean your home
- Allergy testing may help identify specific triggers
Dietary Adjustments
- Try a hydrolyzed protein diet, which breaks down proteins so your pet’s immune system doesn’t react to them
- Or switch to a limited ingredient diet that eliminates common allergens
Year-Round Flea Control
Even one bite can trigger a reaction in flea-allergic pets. Our vets recommend Nexgard Plus for dogs and Nexgard Combo for cats. These provide monthly protection against fleas, ticks, and intestinal parasites.
Prescription Medications
For moderate to severe allergies, your vet may prescribe:
- Antihistamines like Benadryl or Claratin
- Steroids (short term) for flare-ups
- Apoquel or Cytopoint, which target itching at the immune level without the side effects of steroids
Topical Relief
- Soothing oatmeal shampoos
- Medicated creams or sprays to reduce inflammation
- Regular grooming to remove allergens from the coat
