Understanding Dog Allergies

Allergies are the #1 reason dog owners visit the vet. If your dog is constantly scratching, licking their paws, developing red patches, or getting recurring ear infections, allergies are the most likely cause. The good news: most allergies are highly treatable, and a video vet visit is one of the best ways to get started because skin conditions are inherently visual.

There are four main types: environmental allergies (pollen, dust, mold), food allergies (chicken, beef, grains), flea allergy dermatitis (reaction to flea saliva), and contact allergies (cleaning products, grass). Your vet will help narrow down the trigger based on the pattern and location of symptoms.

Allergy Medication Options

Medication	Best For	How Fast	Duration
Apoquel (oclacitinib)	Moderate-severe itching, long-term use	4-24 hours	Daily (ongoing)
Antihistamines (Benadryl, Zyrtec)	Mild allergies, quick relief	30-60 minutes	As needed
Prednisone	Acute flares, severe inflammation	Hours	Short-term only
Antibiotics	Secondary skin infections from scratching	2-3 days	7-14 day course
Medicated shampoo	Topical relief, removing allergens	Immediate soothing	1-2x per week

All medications prescribed at your vet's discretion. Your vet will recommend the safest option based on your dog's age, weight, and health history.

Why Video Visits Work for Allergies

Skin conditions are one of the best uses for telehealth because they are visual. Your vet can see the rash, the redness, and the distribution pattern through your phone camera — often providing the same assessment quality as an in-person exam.

Dog Allergy FAQs

Can an online vet prescribe allergy medication for my dog?

Yes. Licensed veterinarians can prescribe allergy medications including apoquel, antihistamines, steroids, and antibiotics during a video consultation in Florida, New York, and Virginia.

How do I know if my dog has allergies vs something else?

The pattern and location of symptoms are key. A vet can differentiate between allergies, infections, parasites, and other skin conditions during a video examination. If further testing is needed, they will refer you.

Can food allergies be diagnosed online?

A vet can suspect food allergies based on symptoms and recommend an elimination diet trial. True food allergy diagnosis requires an 8-12 week strict diet under vet supervision — the initial consultation and diet plan can absolutely be done via video.

How much does online allergy treatment cost?

A RexVet consultation is $64.99, which includes the diagnosis, prescription, and 48-hour follow-up messaging. In-person allergy visits typically cost $150-$300 before medication.
