There’s a moment most dog owners know well. You’re giving your dog a scratch behind the ears — a perfectly ordinary Tuesday evening —, and you notice something. A patch of dry skin. A spot they keep returning to. A coat that’s lost its shine. Nothing dramatic, nothing urgent. Just a quiet signal that something might be worth paying attention to.
Skin is the body’s largest organ, and in dogs, it’s also one of the most expressive. Long before a condition becomes serious, the skin is often already talking. The question is whether we know how to listen.
Why Dog Skin Health Is More Than Skin Deep
It’s easy to think of skin problems as purely cosmetic — a bit of itching, some flaking, maybe a dull coat. But skin is a reflection of what’s happening internally. Nutrition, immune function, gut health, hormones, and environmental exposure all show up on the surface.
This is actually good news. It means the skin gives you an early window into your dog’s overall wellbeing — if you know what to look for.
Common Signs Your Dog’s Skin Is Under Stress
Persistent Scratching, Licking, or Chewing.
The odd scratch is completely normal. But if your dog is scratching the same spot repeatedly, licking their paws obsessively, or chewing at their tail or legs, their skin is signalling irritation. This kind of repetitive behaviour is often the first sign owners notice — and one of the easiest to dismiss as “just a habit.”
Dry, Flaky, or Scaly Skin
Dandruff isn’t just a human problem. Dry, flaky skin in dogs can point to low humidity, poor diet (particularly a lack of essential fatty acids), dehydration, or an underlying condition like hypothyroidism or allergies.
Redness or Inflammation
Patches of pink or red skin — especially in skin folds, around the ears, between the toes, or on the belly — often indicate irritation, whether from environmental allergens, food sensitivities, or contact with something on the ground.
Hot Spots
Hot spots (acute moist dermatitis) are localised areas of inflamed, infected skin that appear suddenly and can worsen quickly. They’re often triggered by moisture trapped against the skin — think dogs who swim frequently, or thick-coated breeds in humid weather.
Hair Loss or Thinning Coat
Patchy hair loss (alopecia) can stem from several causes: mange, ringworm, hormonal imbalance, or chronic scratching that damages the follicles. A coat that’s thinning evenly across the body, rather than in patches, often points to nutritional or hormonal factors.
Dull, Brittle, or Rough Coat
A healthy dog’s coat should have a natural lustre. If your dog’s fur has lost its sheen, feels rough to the touch, or breaks easily, it’s often a sign their diet lacks the fatty acids and nutrients needed to support skin and coat health.
Unusual Odour
A persistent “doggy” smell even after bathing can indicate an overgrowth of yeast or bacteria on the skin — both of which thrive when the skin’s natural microbiome is out of balance.
What Causes Skin Problems in Dogs?
Skin issues rarely have a single cause. Most of the time, they’re the result of several factors combining, which is also why they can be frustratingly difficult to resolve with a single fix.
Diet and nutrition are one of the most significant contributors. Dogs fed highly processed diets that are low in quality protein and essential fatty acids (particularly omega-3s) are more prone to dry, inflamed skin. The gut and the skin are closely linked — poor digestion often shows up on the surface.
Environmental allergens — pollen, grasses, dust mites, and mould — are a leading causeof allergic skin reactions in dogs. Unlike humans, who tend to sneeze and get runny eyes, dogs typically react to allergens through their skin. New Zealand’s lush environment is beautiful, but it’s also a rich source of potential triggers.
Food sensitivities are another common culprit. Proteins like chicken, beef, dairy, and wheat are among the most frequent dietary allergens in dogs. Food-related skin issues often show up as recurring ear infections, paw licking, and itchy bellies.
Chemical exposure — from flea and tick treatments, lawn sprays, household cleaners, and synthetic grooming products — can irritate the skin directly or tax the body’s ability to manage inflammation over time.
Parasites — fleas, mites, and lice — cause intense itching and can trigger secondary infections from scratching.
Hormonal imbalances — particularly hypothyroidism and Cushing’s disease — often manifest in the skin before other symptoms appear, causing hair loss, thickening, or darkening of the skin.
Breeds More Prone to Skin Issues
Some dogs are simply more predisposed to skin sensitivity due to their genetics or physical structure. If you have one of the following breeds, it’s worth being especially attentive:
Bulldogs, Pugs, and Shar-Peis — skin folds create warm, moist environments where bacteria and yeast thrive
West Highland White Terriers — known for a condition called “Westie skin disease”
(epidermal dysplasia)
Labrador and Golden Retrievers — prone to environmental and food allergies
German Shepherds — frequently affected by eczema and flea allergy dermatitis
Cocker Spaniels — susceptible to seborrhoea and ear infections
Boxers — prone to skin tumours and environmental allergies
What You Can Do
Start with a vet check. If your dog has been scratching or showing skin changes for more than a couple of weeks, get a baseline assessment. Your vet can rule out parasites, infections, or hormonal conditions that need targeted treatment. Look at the diet. Consider whether your dog’s food contains high-quality protein, adequate omega-3 fatty acids (found in fish oil and flaxseed), and minimal artificial additives. Many owners find that switching to a less processed diet makes a meaningful difference over time.
Eliminate potential irritants gradually. If you suspect an environmental or contact allergen, try to identify and reduce exposure — swap synthetic grooming products for gentler alternatives, wipe paws after walks, and avoid areas recently treated with chemical sprays.
Consider a food elimination trial. If food sensitivity is suspected, your vet may recommend a strict elimination diet — typically a novel protein your dog hasn’t eaten before — for 8–12 weeks to see if symptoms improve.
Support from the inside out. Many dog owners explore herbal and nutritional support as part of a broader approach to skin health. Herbs traditionally used for skin and allergy support focus on calming inflammation, supporting the immune system, and helping the body manage its response to irritants.
Traditional Botanicals Associated with Skin and Allergy Support
These herbs have a long history of use in both human and veterinary herbal medicine for supporting healthy skin and reducing the body’s reactivity to allergens:
Nettle Leaf (Urtica dioica) Rich in minerals and traditionally used as a natural antihistamine, nettle leaf has been used for centuries to support the body’s response to allergens and reduce inflammation.
Burdock Root (Arctium lappa) A classic “blood purifier” in traditional herbalism, burdock root is associated with skin health and is often used to support conditions like eczema and dermatitis.
Calendula (Calendula officinalis) Known for its soothing, anti-inflammatory properties, calendula is used both topically and internally to support skin comfort and healing.
Licorice Root (Glycyrrhiza glabra) Traditionally used as a natural alternative to cortisone for calming skin inflammation and reducing itch. It should be used carefully and in appropriate amounts.
Aloe Vera Well-known for its cooling, soothing properties when applied topically to irritated or inflamed skin.As always, consult your vet before introducing herbal supplements, particularly if your dog has existing health conditions or is on medication.
Listening to What the Skin Is Saying
Skin problems in dogs can be frustrating — they’re often slow to resolve and quick to return. But they’re also remarkably informative. Every patch, every scratch, every dull coat is your dog’s body communicating something worth understanding.
The most effective approach is nearly always a whole-body one: clean nutrition, reduced chemical load, targeted treatment where needed, and gentle support for the systems that keep inflammation in check.
At Herb & Hound Co., that’s the philosophy behind everything we make. Start with the dog in front of you, understand what their body needs, and work with it — not against it.
