Itchy Dog? Here’s What Might Be Causing It (And How Omega-3 Can Help)

When Scratching Isn’t “Just Scratching”

A quick scratch behind the ear or a casual belly rub on the rug? Totally normal.

But if your dog is constantly licking, chewing, or rubbing their skin, there might be more going on than just an occasional itch. In fact, chronic itching in dogs is often a sign of underlying skin issues, allergies, or nutritional imbalances.

Here’s how to tell when it’s more than "just being a dog"—and how to help, starting today.

Signs Your Dog’s Skin Needs Support

  • Excessive licking of paws or belly
  • Scratching that doesn’t stop
  • Red, inflamed, or flaky patches
  • Hair loss or thinning coat
  • Rubbing face on carpet or furniture

If you’re seeing one or more of these signs regularly, it’s time to investigate.

Most Common Causes of Itchy Skin in Dogs

1. Seasonal Allergies

Dogs can react to pollen, mold, grass, and dust just like humans. Seasonal flare-ups often show up as paw licking, ear irritation, and all-over itching.

2. Food Sensitivities

Ingredients like chicken, beef, dairy, or grains can cause chronic itching and ear infections in sensitive dogs.

3. Dry Skin (Especially in Winter)

Cold air, dry heating, or over-bathing with harsh shampoos can strip your dog’s skin of natural oils.

4. Fleas and Parasites

Even one flea can cause a major allergic reaction in sensitive dogs. Year-round flea control is key.

5. Nutritional Deficiencies

A lack of essential fatty acids, especially omega-3, can lead to dry, itchy, inflamed skin and dull coat.

Why Omega-3 for Dogs Is a Skin Saver

Omega-3 fatty acids, especially EPA and DHA found in salmon oil, have been shown to:

  • Reduce inflammation
  • Relieve skin allergies and hot spots
  • Improve coat texture and shine
  • Support the skin’s natural moisture barrier
  • Help calm overactive immune responses in allergic dogs

Unlike topical treatments, omega-3 works from the inside out, making it one of the most effective long-term strategies for dogs with chronic itchiness or skin allergies.

When to Call the Vet

If your dog’s itching is severe or accompanied by:

...make an appointment with your vet. Issues like skin infections, mites, or thyroid disorders may need prescription treatment.
