Constant scratching driving you both crazy? Here are the most common reasons your dog is itchy and what to do about each one.

The usual suspects

Itching almost always comes down to one of four things: fleas, allergies (environmental or food), dry skin, or a skin infection. Identifying which is happening is the key to real relief.

Fleas come first

Even one flea can trigger intense itching in sensitive dogs. Before anything else, make sure flea prevention is current — flea allergy dermatitis is the single most common cause of itching. A preventive like [NexGard](/products/nexgard-chewables-for-dogs) rules it out.

Allergies and dry skin

Environmental allergens (pollen, dust) and food sensitivities cause chronic itching, often with red skin and ear infections. Omega-3 supplements like [Zesty Paws Omega Bites](/products/zesty-paws-omega-bites-salmon-chews) strengthen the skin barrier, and a humidifier or gentler shampoo helps dry, flaky skin.

When it's an infection

Yeast or bacterial infections cause intense itching, odor, and greasy or crusty skin. These need veterinary treatment — home remedies won't clear them.

When to see the vet

If your dog is chewing themselves raw, losing hair, or the itching won't stop, see your vet. Chronic itching needs a diagnosis, not guesswork.
