Allergy Testing and Treatment
for Dogs and Cats

Pet allergies rarely look like ours. Instead of sneezing, dogs and cats show it through their skin: constant scratching, licking or chewing at the paws, red or irritated skin, hair loss, hot spots, and recurring ear or anal gland infections. Some pets get digestive trouble like vomiting or soft stool, especially with food allergies. And because scratching breaks the skin, untreated allergies often turn into infections on top of the itch. Allergies can begin at any age, so a pet who suddenly becomes itchy at five or six isn’t unusual. One more sign worth knowing: sudden facial swelling or hives after a sting, a new food, or a medication deserves a call right away.

Environmental allergies (pollen, dust mites, mold)

The most common group, pollen, grass, trees, mold, and dust mites. These often start seasonal and become year-round as sensitivities build. Vets call it atopy or atopic dermatitis; your pet just calls it itchy.

Flea allergy dermatitis

It takes only one bite. Pets allergic to flea saliva can react intensely to a single flea, often around the tail base and back end, which is why year-round flea prevention is step one of any allergy plan.

Food allergies (chicken, beef, and other proteins)

Less common than people think, but very real, and usually triggered by proteins like chicken or beef rather than grains. Food allergies tend to show up as itchy skin and recurring ear infections, sometimes with digestive upset alongside.

We start with a proper exam, because plenty of itchy skin isn’t allergy at all, fleas, mites, ringworm, and skin or ear infections can look nearly identical, and a quick skin or ear cytology rules them in or out. For environmental allergies, blood testing can identify which triggers your pet reacts to, which guides avoidance and opens the door to allergy shots. Food allergies are different: no blood test diagnoses them reliably. The honest answer is a properly run elimination diet, usually eight to twelve weeks on a prescription diet and nothing else, which we’ll plan and support with you step by step. Either way, we’ll tell you plainly what a test can answer, what it can’t, and whether it’s worth running for your pet.

Relief usually comes from layers, not one magic fix, removing triggers where possible, year-round flea control, medicated baths and skin care, modern anti-itch medications that work quickly, allergy shots (immunotherapy) for long-term desensitization, prescription diets for food-allergic pets, and properly treating any secondary skin or ear infections. Allergies are managed rather than cured, so we build a plan for the long run, including what to do when a flare hits, and adjust as your pet’s needs change.
