Allergies are a common cause of itching, skin problems and ear infections in dogs and cats. Pets can be allergic to things in their environment, like pollen, dust mites and mold, to fleas, or to ingredients in their food.

Allergy testing helps your vet understand what may be triggering your pet's symptoms, so treatment can target the cause instead of only easing the itch.

Signs Your Pet May Have Allergies

Allergy signs often show up on the skin and ears. Watch for:

  • Scratching, licking or chewing, especially the paws
  • Red, irritated or flaky skin
  • Hair loss or hot spots
  • Repeated ear infections or head shaking
  • Rubbing the face on furniture or the floor
  • Vomiting or diarrhea with some food allergies

Symptoms that get worse in certain seasons can point to environmental allergies, while year-round signs may suggest other causes.

How Allergy Testing Works

Your vet starts with a thorough exam and history to rule out other causes of itching, such as fleas, mites and infections. Depending on your pet's signs, testing may include bloodwork for environmental allergies or a strict elimination diet trial to check for food allergies.

Once the likely triggers are known, your vet will build a treatment plan that may include avoiding triggers, medications, special diets, skin and ear care, or allergy immunotherapy to help reduce your pet's reaction over time.

Allergy Testing: Frequently Asked Questions

Can a blood test diagnose food allergies?
Not reliably. The best way to diagnose a food allergy is an elimination diet trial, where your pet eats a special diet for several weeks. Your vet will guide you through the process.
Is my pet too young for allergy testing?
Allergy signs often appear between one and three years of age. Your vet will consider your pet's age, history and symptoms when deciding if and when testing is right.
Can allergies in pets be cured?
Most allergies can't be cured, but they can usually be managed well. Avoiding triggers, medications, special diets and allergy immunotherapy can help keep your pet comfortable.
Should my pet stop any medications before allergy testing?
Sometimes. Certain medications, like steroids and antihistamines, can affect test results. Don't stop any medication on your own. Your vet will tell you exactly what to do before testing.
