They can appear at any age, and the symptoms are often subtle enough that weeks may pass before you realize your pet is actually having an allergic reaction.
The most common sign that something is wrong is itchiness. A dog or cat may start licking themselves more often, nibbling on their paws, rubbing their face against furniture, or scratching intensely around the ears, belly, or back. Some pets develop redness, flaky skin, hair loss, or small sores caused by excessive scratching. Cats can be especially tricky – they may simply over-groom, so thinning fur might be the only clue.
Allergies may be triggered by food, dust, pollen, mites, fleas, or various substances in the home – even detergents or air fresheners. Because of this, pinpointing the exact cause can be challenging at first, but your veterinarian can recommend elimination diets, allergy tests, or treatments that help ease the symptoms.
The key is early action. If you notice persistent itching, skin redness, frequent head shaking, or thinning fur, it’s best to schedule a veterinary visit as soon as possible. With proper nutrition, treatment, and a few adjustments in the environment, most allergies can be successfully managed – and your pet can quickly return to their happy, carefree routine.
