How to Recognize Allergy Symptoms in Your Pet

Allergies in dogs and cats can show up in many different ways, and sometimes the signs are easy to miss at first. Key symptoms of pet allergies include persistent scratching, chewing, or licking—often focusing on the paws, belly, ears, or base of the tail. Additionally, you might notice hair loss, red or inflamed skin, frequent head shaking, or scabs. In some cases, pets develop recurring ear infections, which may be a sign of underlying allergies rather than just a problem with ear hygiene.

Respiratory symptoms are less common than skin issues, but some pets do experience sneezing, watery eyes, or nasal discharge. Other signs to watch for are excessive licking of the feet after walks, chewing at the sides or flanks, or rubbing the face along carpets and furniture. Cats, in particular, may show signs by overgrooming, which results in bald patches or skin sores. If your pet has digestive upset—such as vomiting or diarrhea—along with skin or respiratory symptoms, food allergies may also be involved.

It is important to remember that these symptoms can result from a range of health issues, not just allergies. Parasites, infections, and other conditions may look similar. That is why a thorough veterinary evaluation is essential for getting your pet the right care.

Why Do Pets in San Francisco Get Allergies?

San Francisco’s mild, damp winters and early springs create unique challenges for pets with allergies. Unlike regions with harsh freezes that kill off many allergens, our area’s year-round vegetation, mold growth, and urban pollutants provide a steady supply of potential triggers. Common causes of pet allergies include environmental allergens such as pollen from trees, grasses, and weeds, as well as mold spores and dust mites. With our city’s famous parks and green spaces, pets are often exposed to these irritants during daily walks.

Flea allergies are another frequent culprit. Even one or two flea bites can trigger intense itching in sensitive dogs and cats, making diligent flea prevention critical no matter the season. Food-related allergies can also play a role, often manifesting as chronic skin problems or gastrointestinal symptoms. In urban environments like San Francisco, pets may encounter additional irritants from air pollution, cleaning products, and even certain fabrics in the home.

Genetics matter as well. Some breeds are more prone to allergies, including terriers, retrievers, bulldogs, and many purebred cats. Finally, indoor allergens such as dust, mold, and even feathers from bedding can contribute to year-round allergy misery for sensitive pets.

Professional Treatment Options for Pet Allergies

If you suspect your pet is suffering from allergies, the first step is a comprehensive evaluation with our veterinary team. At South Park Animal Hospital, we take a detailed history, perform a physical examination, and may recommend specific tests to rule out other causes of itching or inflammation. For many pets, allergy testing services help us pinpoint the source of the problem—whether it is environmental, food-related, or something else entirely.

Treatment approaches for pet allergies often involve a combination of strategies. For pets with flea allergies, strict flea prevention is non-negotiable, and we can recommend safe, effective products tailored to your pet’s needs. When environmental allergies are the cause, therapies may include medicated shampoos, topical sprays, or oral medications that control itching and inflammation. Our dermatology services for pets are designed to address stubborn skin issues, from secondary infections to chronic ear problems.

In some cases, immunotherapy—or allergy shots—may be advised, especially if your pet’s symptoms are severe or poorly controlled. This treatment gradually builds tolerance to specific allergens but requires a commitment of time and follow-up appointments. For food allergies, we may recommend a trial of prescription diets or elimination diets to identify offending ingredients.

Throughout the process, our veterinarians work closely with you to monitor your pet’s response and adjust the treatment plan as needed. Our goal is always to help your pet feel comfortable and minimize the impact of allergies on daily life.

Home Care and Prevention Tips for Pet Allergies

While professional care is crucial, there are practical steps you can take at home to reduce your pet’s exposure to allergens and support their recovery. Regular bathing with a gentle, vet-recommended shampoo helps remove pollen, dust, and other irritants from your pet’s coat and skin. Wiping your dog’s paws and belly after walks can prevent allergens from being tracked inside and causing additional irritation.

Vacuuming frequently, washing pet bedding in hot water, and using air purifiers can help reduce indoor allergens. Flea prevention should be maintained consistently, even during the cooler months, since San Francisco’s climate supports fleas year-round. For pets with food sensitivities, feeding only the prescribed diet—without table scraps or treats containing unknown ingredients—is essential.

Managing stress is another important aspect, as anxious pets often scratch or overgroom more. Providing plenty of mental stimulation, exercise, and comfort can make a significant difference in your pet’s overall wellbeing.

If you ever notice changes in your pet’s symptoms or new issues developing, keep a diary of flare-ups, possible exposures, and dietary changes. This information can be invaluable at your next veterinary appointment and helps our veterinarians refine your pet’s treatment plan.

When to Seek Veterinary Care for Pet Allergies

Although mild, occasional itching or sneezing can sometimes be managed at home, there are clear signs that your pet needs professional veterinary evaluation. If your dog or cat is scratching or licking so much that they develop bald spots, sores, bleeding, or scabs, it is time to schedule an appointment. Persistent ear infections, red or swollen skin, changes in appetite, vomiting, or diarrhea are also signals that a deeper issue may be present.

For pets who suddenly become lethargic, have difficulty breathing, or experience swelling of the face or throat, seek emergency care right away, as these may indicate a severe allergic reaction. In most cases, earlier intervention leads to better outcomes and prevents minor problems from becoming major health concerns.

At South Park Animal Hospital, we offer same-day urgent care appointments for pets experiencing sudden or severe allergy symptoms.
