Itchy Dogs & Biting Insects: An Overlooked Cause of Summer Scratching
If your dog is constantly scratching, licking, or chewing at their skin — especially during warmer months — biting insects could be the hidden cause.
In tropical and coastal regions such as Darwin, Cairns, and Broome, insects are active year-round. Midges, mozzies, flies, and even ants can all trigger intense itchiness and skin irritation in dogs, sometimes without owners realising what’s behind the problem.
The Common Culprits: Tiny Bites, Big Irritation
🦟 Midgies (Biting Midges / Sandflies)
Midgies are tiny but notorious. They’re most active at dawn and dusk and thrive in humid, coastal, and mangrove areas. Their bites can cause intense itching, redness, and swelling — and some dogs develop allergic reactions that lead to ongoing skin issues.
🦟 Mozzies (Mosquitoes)
Mosquitoes don’t just bother humans. Dogs can be repeatedly bitten on areas with less fur coverage, leading to raised welts, hot spots, and relentless scratching. Mozzies are especially active in the evening, overnight, and early morning.
🪰 Flies
Biting flies tend to target ears, bellies, and legs. Repeated bites can cause inflamed patches, scabs, and broken skin — particularly in dogs that spend long periods outdoors.
🐜 Ants
Ant bites are often overlooked but can cause clusters of small, painful, itchy bumps, especially on paws, bellies, and lower legs where dogs lie on grass or soil.
Which Dogs Are Most at Risk?
Some dogs are far more vulnerable to insect bites than others, including:
• Short-coated or lightly coated dogs
• Dogs with thin skin or pale pigmentation
• Dogs that sleep outdoors
• Dogs outside overnight, at dawn, or at dusk
• Dogs living in tropical, coastal, or wet environments
If your dog fits one or more of these categories, insect tox-free protection is especially important.
How to Identify Insect Bites on Dogs
Insect bites can look different from allergies or fungal skin issues. Signs to watch for include:
• Small raised bumps or welts
• Red spots, often with a visible centre
• Clusters of bites in one area
• Sudden intense itching or licking
• Swelling on ears, muzzle, belly, or legs
• Restlessness or irritation that’s worse at night
Because bites can trigger secondary infections if scratched, early identification matters.
Natural Ways to Help Protect Your Dog
Reducing exposure is key — limiting outdoor time at peak insect hours, using fans where possible, and supporting the skin barrier all help. But in high-insect areas, natural repellents can make a huge difference.

When to Seek Extra Help
If your dog’s itching is severe, persistent, or worsening — or if you notice broken skin, oozing, or hair loss — it’s important to seek veterinary advice. Insect bites can trigger allergic dermatitis, which may need additional support.
Final Thoughts
