Quick Answer

Common Yorkie allergy symptoms include itching, red or inflamed skin, scratching or chewing (especially paws and belly), sneezing, runny eyes, recurrent ear issues, and sometimes vomiting or loose stools. Allergies can be environmental (pollen, dust, mold), food-related, or contact (e.g. cleaning products). There’s no home test that replaces a vet—see the vet for diagnosis and a plan. At home you can reduce triggers (e.g. hypoallergenic shampoo, limited-ingredient or sensitive-stomach food, clean bedding) and avoid human allergy meds unless the vet prescribes them.

Types of Allergies in Yorkies

Type	Examples of triggers	Typical signs
Environmental (inhalant)	Pollen, dust mites, mold spores	Itching, sneezing, watery eyes, licking paws, seasonal or year-round
Food	Chicken, beef, dairy, wheat, soy, eggs	Itchy skin, ear infections, vomiting, diarrhea, sometimes year-round
Contact	Detergents, floor cleaners, certain fabrics	Redness, itching where skin touches the trigger
Flea	Flea bites (saliva)	Intense itching, especially base of tail and back; flea dirt visible

Many dogs have a mix (e.g. food plus environmental). Your vet can help narrow down causes with history, exam, and sometimes diet trials or testing.

Symptoms to Watch For

Skin and Coat

• Itching (pruritus) — scratching, chewing, rubbing on furniture.
• Red or inflamed skin — especially belly, paws, armpits, ears.
• Hair loss or thinning — from repeated scratching or chewing.
• Rashes, hives, or hot spots — moist, red, painful patches.
• Dull or greasy coat — can go with skin inflammation.

See Yorkie skin problems for more on skin conditions and when they might be allergy-related.

Eyes, Ears, and Nose

• Watery or red eyes — can be allergy or tear staining; vet can distinguish.
• Recurrent ear infections — allergies often contribute; see ear care.
• Sneezing or runny nose — more common with environmental allergens.

Digestive

• Vomiting or diarrhea — especially with food allergy; can be intermittent.
• Gas or bloating — sometimes linked to food intolerance.

When to See the Vet Soon

• Face or throat swelling — can block breathing; emergency.
• Severe or sudden vomiting/diarrhea — risk of dehydration.
• Difficulty breathing — emergency.
• Persistent itching or skin infection — to get a diagnosis and avoid self-treatment that could worsen things.

Diagnosis: What the Vet May Do

• History and exam — when and where itching happens, diet, environment.
• Diet trial — strict limited-ingredient or hydrolyzed diet for 8–12 weeks to rule out food allergy; no other foods or flavored meds.
• Skin or blood testing — for environmental allergens; helps target immunotherapy (allergy shots) or avoidance.
• Ruling out other causes — parasites, skin infections, hormonal issues.

There’s no single “allergy test” that replaces a vet’s assessment; over-the-counter or at-home tests are not reliable for planning treatment.

Treatment and Management

Approach	What it does
Avoidance	Remove or reduce trigger (e.g. new diet, hypoallergenic bedding, fewer chemicals).
Medication	Antihistamines, steroids, or other drugs as prescribed to control itch and inflammation.
Immunotherapy (allergy shots)	Long-term option for environmental allergies; vet formulates from test results.
Skin and coat care	Bathing with a gentle, hypoallergenic shampoo to remove allergens; regular grooming and ear cleaning.
Diet	For food allergy: vet-recommended limited-ingredient or hypoallergenic diet; no table scraps or other foods during the trial.

Never give human allergy or cold medicines without vet approval; some (e.g. xylitol, certain decongestants) are toxic to dogs.

Home Care and Prevention

• Bathe and groom — Hypoallergenic shampoo and regular brushing to remove pollen and dander. Don’t over-bathe (can dry skin); follow vet or product guidance.
• Wash bedding — Launder dog beds and blankets regularly; use fragrance-free detergent if your dog is sensitive.
• Limit exposure — Wipe paws after outside if pollen is a trigger; avoid walking in high pollen when possible.
• Diet — Stick to the vet’s diet plan; avoid treats or foods that could undermine a food trial. For general sensitivity, see best food for sensitive stomachs.
• Flea control — Year-round flea prevention if flea allergy is suspected or you live in a flea area.

Hypoallergenic Breed Myth

Yorkies are often called “hypoallergenic” because they tend to shed less, so some people with allergies tolerate them better. Hypoallergenic does not mean allergy-free. Yorkies can still trigger human allergies (dander, saliva), and Yorkies themselves can have allergies—to food, pollen, or other triggers. If you or your dog have allergy symptoms, work with a doctor or vet for a proper plan.

Frequently Asked Questions

What are the most common allergy symptoms in Yorkies?

Itching, scratching, chewing (especially paws), red or inflamed skin, recurrent ear infections, sneezing, watery eyes, and sometimes vomiting or diarrhea. See the vet to confirm allergy vs other causes.

Can Yorkies have food allergies?

Yes. Common triggers include chicken, beef, dairy, wheat, and soy. Diagnosis is usually by an 8–12 week strict diet trial with a vet-recommended limited-ingredient or hydrolyzed diet.

What can I give my Yorkie for allergies at home?

Don’t give human allergy meds unless the vet prescribes a dog-safe option and dose. At home you can reduce triggers: hypoallergenic shampoo, clean bedding, wiping paws, and a vet-approved diet. For itch relief and medication, follow the vet’s plan.

When should I take my Yorkie to the vet for allergies?

Go when itching or skin problems are new, worsening, or not improving with basic care; when there’s face swelling, trouble breathing, or severe vomiting/diarrhea (emergency); or when you want a proper diagnosis and long-term plan.
