Why Spring Is Miserable for Allergic Pets in San Jose
The Bay Area's mild winters mean an early and aggressive pollen season. Oak, grass, and weed pollens peak from March through June, and mold spores thrive in the region's coastal fog and spring rains. For allergic dogs and cats, this means months of itching, ear infections, and skin problems. Unlike humans who get sneezy and watery-eyed, pets typically show allergies through their skin — constant scratching, chewing paws, and recurring ear infections.
Common Signs of Seasonal Allergies in Dogs
Excessive scratching, especially around the face, ears, armpits, belly, and paws. Red, inflamed skin or hot spots. Chronic ear infections (head shaking, brown discharge, odor). Chewing or licking paws until they're stained red-brown. Rubbing face on carpet or furniture. Hair loss in patches. Watery eyes. Recurrent skin infections. Symptoms typically worsen after outdoor activity and improve with bathing or staying indoors.
Seasonal Allergies in Cats
Cats show allergies differently than dogs. Look for: overgrooming leading to bald patches (especially on the belly and legs), miliary dermatitis (tiny scabs along the back and neck), facial swelling or puffy eyelids, sneezing and nasal discharge, and asthma-like symptoms (coughing, wheezing, labored breathing). Feline asthma can be triggered by environmental allergens and is a serious condition requiring veterinary treatment.
Allergy Testing and Diagnosis at ARCH
Our veterinarians diagnose seasonal allergies through a combination of clinical history (timing of symptoms), physical examination, ruling out other causes (flea allergy, food allergy, skin infections), and intradermal or blood-based allergy testing when needed. Allergy testing identifies specific environmental triggers, which can guide immunotherapy (allergy shots or drops) — the only treatment that addresses the root cause rather than just managing symptoms.
Treatment Options Available at ARCH Veterinary
Apoquel: Fast-acting anti-itch medication that works within 4 hours. Safe for long-term use. Cytopoint: Injectable antibody therapy that targets itch at its source. One injection lasts 4–8 weeks. Immunotherapy (allergy shots): Custom-formulated based on your pet's specific allergens. The only treatment that can reduce or eliminate allergic reactions over time. Medicated baths: Prescription shampoos with chlorhexidine or phytosphingosine to reduce skin bacteria and soothe inflammation. Ear treatments: Targeted therapy for allergy-related ear infections. Antihistamines: Sometimes helpful for mild cases but less effective than newer options. Our team will create a customized treatment plan based on your pet's severity and lifestyle.
Home Management Tips for Allergy Season
Wipe your pet's paws and belly with a damp cloth after every outdoor walk. Bathe your pet weekly with a gentle or medicated shampoo. Wash pet bedding weekly in hot water. Use HEPA air purifiers in rooms where your pet spends time. Keep windows closed during high-pollen days. Avoid walking through tall grass or freshly mowed lawns. Feed a high-quality diet with omega-3 fatty acids to support skin barrier function. Schedule a pre-season visit with ARCH Veterinary to start allergy management before symptoms peak — call (669) 230-5034 or (408) 224-5700.

Frequently asked questions
When is allergy season for pets in San Jose?
Bay Area allergy season typically runs from March through June (grass and tree pollen), with a secondary peak in fall (weed pollen). Some pets have year-round allergies due to dust mites and mold.
What is Cytopoint and does ARCH offer it?
Cytopoint is an injectable antibody therapy that blocks the itch signal in dogs. One injection lasts 4–8 weeks with minimal side effects. Yes, ARCH offers Cytopoint at both our Winchester and Santa Teresa locations.
Can I give my dog Benadryl for allergies?
Benadryl (diphenhydramine) is generally safe for dogs at 1 mg per pound of body weight, but it's often insufficient for moderate to severe allergies. Newer medications like Apoquel and Cytopoint are far more effective. Consult our team for the best option.
