Pet Dander 101: What It Is And Why It Matters

Pet Dander 101: What It Is And Why It Matters

April 10, 2026

If you or someone in your home has allergies, “pet dander” is often the phrase that comes up first—especially when symptoms flare around pets. Pet dander is not a single thing you can point to on a couch or a blanket; it’s a collection of microscopic allergen-carrying particles that come from animals. In general, pet allergies happen when your immune system reacts to specific proteins found in animal skin cells (dander) and also in other animal materials like saliva or urine [1]. The result can feel like your home is “full of allergies,” even when the pet isn’t in the room.

Hayfever Relief: When “Decongestant” Makes Sense (and When it Doesn’t)

April 10, 2026

If you’ve ever had hayfever, you know the feeling: one minute you’re fine, and the next your nose is blocked, you’re sneezing, and you can’t stop rubbing your eyes. Hayfever rhinitis is the common name many people use for allergic rhinitis—nose symptoms triggered by inhaled allergens like pollen, mold, dust, or pet dander. The body’s immune response causes inflammation in the nasal lining, which leads to classic symptoms such as sneezing, a runny or stuffy nose, and itching.

Can you get a fever from allergies?

April 10, 2026

If you’ve ever felt warm, flushed, or “kind of sick” during a high-allergen day, it’s natural to wonder: can you get a fever from allergies? In most cases, true fever is not caused by allergies. Allergies—like allergic rhinitis (“hay fever”)—can cause symptoms such as sneezing, itchy/watery eyes, nasal congestion, and post-nasal drip, but they typically do not trigger the kind of fever you see with infections. The American College of Allergy, Asthma & Immunology (ACAAI) specifically notes that the idea that allergies cause fever isn’t true, and that allergic rhinitis does not cause a fever even though it can feel miserable

Understanding Pet Allergies: From Dog Epithelium to Coughing and Angioedema

February 26, 2026

Pet allergies can feel confusing because the trigger isn’t “fur” in the way most people imagine. The real issue is proteins that come from a dog’s body—especially skin cells (epithelium/dander), saliva, and urine—that end up on fur, furniture, and in the air.
