Common Signs of Allergies in Pets

Pet Care Tips 3 min read

Our furry kiddos can be sensitive to a lot of allergens out there in the world. For example, environmental allergens, foods, and even flea bites can cause immune reactions leading to allergies, affecting their comfort and health.

If you suspect allergies trouble your fur kiddo, make sure you get a proper diagnosis from the vet. Acute and chronic allergies can cause irritation, inflammation, and various other health issues – some of which can be life-threatening. To provide supportive care at home, certain supplements may help soothe these reactions.

Signs to Watch Out For

Allergens are any substance that triggers an overreaction in the immune system

Allergens are any substance that triggers an overreaction in the immune system. When pets breathe in or come into contact with these tiny particles, they can produce symptoms such as itching, sneezing, and/or watery eyes.

One of the clearest signs that a pet suffers from an allergy is itchiness. Allergic pets may get red, irritated, or inflamed skin. They may try to soothe themselves by scratching, biting, and licking the area. Certain spots may appear as pimple-like structures that are red and may fail to heal easily. Try to examine regions your pet seems to concentrate on or areas that appear to irritate your pet the most. If you spot redness or bumps, it may be a sign of an allergic reaction.

Another common sign is itching or scratching. If your pet scratches behind the head and ears, shakes or tilts their head, and appears sensitive when you touch them, they may be struggling with an allergy.

Sources of Allergens for Pets

There are many sources of that can cause allergies in pets, each of which can cause an inflammatory response in your fur kiddo. One of the primary causes is environmental allergens; that is, allergens that come from their surroundings indoors and out.

Outdoor sources of allergens include:

  • Pollen – from flowers, trees, and other plants, pollen can cause allergic reaction
  • Mold – pets can get into moldy things on their outdoor adventures, especially during spring
  • Grass – even grass can sometimes irritate certain fur kiddos

These allergens can even affect pets that remain indoors as we track them indoors. To help minimize this, remove your shoes and wipe your pet’s paws when they come indoors.

Even indoor fur kiddos aren’t protected from allergens. Indoor allergens can lurk in fabric, furniture, and other common items.

  • Dust mites – these tiny pests thrive in bedding, carpets, and other fabric. Wash pet beds often
  • Fleas – the bites from fleas can cause allergic reactions and itchiness
  • Cleaning products – certain ingredients in cleaners, air fresheners, and sprays can irritate the respiratory system and skin
  • Smoke – smoke from cooking or cigarettes can irritate your fur kiddo
  • Mold – damp basements or bathrooms may harbor mold spores
  • Food – alleviate food allergies by identifying potential triggers with your vet

To help keep pets healthy indoors, clean spaces and fabrics regularly with natural and pet-safe detergents and cleaners. To help minimize indoor pollutants coming from outside, a HEPA air purifier may help.

Natural Support for Pets with Allergies

Alongside veterinary care, natural supplements may help support your pet’s immune system when in overdrive due to pesky allergies.
