Itching in dogs: causes, symptoms and solutions – including the right diet

If your dog keeps scratching, licking their paws or rubbing their face against furniture, they’re likely suffering from itching (pruritus). This is one of the most common reasons for a veterinary consultation, because it can quickly become a vicious cycle: scratching damages the skin, which increases inflammation – and therefore itching.

While parasites and allergies are common triggers, nutrition also plays a major role in supporting the skin barrier. An adapted diet can help reduce inflammation and provide the nutrients needed for healthier, calmer skin.

What does itching in dogs mean?

Itching is an unpleasant sensation that makes your dog want to scratch, lick or bite their skin. It is not a diagnosis in itself, but a symptom that can be caused by many factors: parasites, allergies, infections (bacteria/yeast), dry skin, or even stress.

When itching becomes chronic, it can lead to hair loss, scabs, thickened skin and secondary infections. That’s why it’s important to identify the cause early and support the skin both externally (appropriate care) and internally (nutrition).

The different types of itching

There are several forms of pruritus depending on its cause and where it appears.

  • Allergic itching is one of the most common, and can be caused by reactions to fleas, environmental allergens (dust mites, pollen) or food components.
  • There is also infection-related itching, caused by bacteria or fungi (mycoses), which can develop on weakened skin.
  • Finally, certain metabolic or hormonal disorders can make the skin dry and irritated, causing more diffuse discomfort.

Where the itching occurs helps identify the underlying cause. Each type of itching requires a specific approach to soothe irritation and strengthen the skin’s natural defences – while preventing scabs or unpleasant odours from developing.

When should you see a veterinarian?

Although diet can provide considerable support, certain situations require professional advice.

If you notice your dog’s skin has oozing wounds, significant scabs or an unusual odour, a consultation is necessary.

Likewise, a dog that scratches to the point of no longer sleeping or stopping eating is expressing pain that must be identified quickly. The veterinarian will be able to rule out serious conditions and make sure the lesions are not secondarily infected. Early intervention helps prevent the problem from worsening and allows an appropriate care protocol to be put in place.

Dog Chef also works closely with nutrition experts to ensure its recipes effectively support the work of veterinary clinics.

Diagnosing itching

To identify precisely why your dog is scratching, a rigorous process is generally followed. Diagnosis often begins by excluding parasites through strict anti-parasite treatment.

If symptoms persist, skin tests or blood tests may be performed. If food sensitivity is suspected, an elimination diet is the reference method: it consists of feeding the animal a single, new protein source for several weeks.

This step requires patience but is crucial to determine whether the ingredients in their current bowl are responsible. Careful observation of where redness appears and how often scratching occurs also helps guide the investigation.

Treatments for itching

Relieving pruritus often relies on a combination of different solutions. Depending on the identified origin, specific shampoos may be used to clean the dog’s epidermis and soothe the skin.

In some cases, temporary use of food supplements or local care based on aloe, for example, helps calm immediate irritation. If inflammation is too strong, more targeted solutions may be considered to break the scratching cycle.

The goal is always to restore the dog’s comfort while addressing the root cause. A global approach including rigorous environmental management and high-quality nutrition helps limit the use of heavy chemical solutions and maintain healthy skin balance in the long term.

 

 

Natural solutions and a holistic approach

Many owners turn to natural remedies to support their pet’s skin.

Coconut oil, thanks to its moisturising properties, can be applied locally to dry areas. Using plants with soothing properties, such as chamomile as a compress, also helps calm minor redness. However, the most effective natural solution remains a raw/less processed diet and one rich in omega-3.

By avoiding colourings, artificial flavours and chemical preservatives, the toxic load on the body is considerably reduced.

A holistic approach also considers the dog’s emotional well-being and the quality of their environment. By combining gentle care and fresh nutrition, you give your companion the best chance of regaining calm skin without stressing their metabolism.

The central role of diet

Skin reflects your dog’s internal health. Unsuitable nutrition, rich in ultra-processed ingredients or low in essential fatty acids, can promote a general inflammatory state.

Conversely, a balanced diet provides the essential building blocks to rebuild the skin barrier. High biological value proteins are essential for keratin synthesis, while vitamins (notably vitamin E and the B complex) support cellular regeneration.

Diet is not only about feeding the animal – it acts as real metabolic support. By choosing fresh, natural ingredients, you allow the body to better manage external aggressions and maintain supple skin that is less prone to irritation and everyday itching linked to nutritional deficiency.

How to switch to fresh food

Successfully transitioning to fresh food is essential, especially for a dog whose body is already strained by itching.

We recommend a transition period of 7 to 10 days.

Start by adding 25% Dog Chef to their usual ration for two days, then move to 50% for the next three days, and finally to 75%. This gradual approach allows the digestive system and skin metabolism to adapt to new nutrients without stress.

During this period, carefully observe changes in behaviour: a gradual decrease in pruritus is often the first positive sign.

Once the transition is complete, deeper benefits on skin structure and coat quality generally stabilise after one month on an exclusive diet.

Frequently asked questions

A dog never itches for no reason; pruritus is always a sign of discomfort. If you don’t see fleas, the origin may be environmental sensitivity (dust mites, pollens) or a reaction to certain components of their food. Sometimes, compulsive licking can also reflect stress or anxiety. Careful observation of when they scratch will help identify the underlying cause.

Causes are multiple and varied. External parasites such as fleas remain the main cause, but allergies to dust mites or grasses are common. Diet also plays a major role: intolerance to a protein or chemical additives can weaken the skin barrier. Finally, hormonal disorders or bacterial infections can make the skin dry, reactive and particularly irritable.

The priority is to identify and eliminate the irritating agent. After checking for parasites, you can soothe the epidermis with gentle local care. Long term, offering a diet rich in essential fatty acids helps strengthen the skin from within. If itching persists or lesions appear, it is important to ask a professional for advice to avoid any secondary infection.

A fresh, natural and minimally processed diet is ideal to support sensitive skin. Choose recipes containing high-quality protein sources and whole ingredients, with no preservatives or artificial flavours. Omega-3 intake is crucial to maintain skin hydration and naturally reduce inflammation, providing long-lasting comfort for your loyal companion.

Several natural solutions can provide immediate relief. Aloe vera or coconut oil applied locally help hydrate dry, irritated areas. Internally, fish oil or cod liver oil boosts the skin’s resistance. However, a fresh and balanced diet – acting as overall support for the body – remains the best natural way to prevent recurring everyday itching in the long term.

There isn’t one single food responsible for itching, because every dog is different. However, certain animal proteins (such as beef or chicken) or cereals are sometimes involved in food intolerances. Additives, colourings and preservatives found in many industrial kibbles are also frequent irritants that can trigger inflammatory skin reactions in sensitive dogs.

Use only a gentle, hypoallergenic shampoo specifically formulated for canine pH balance. Washing with lukewarm water helps remove environmental allergens (pollen, dust, fleas) from the coat without stripping the skin’s hydrolipid film. Rinse thoroughly and dry your dog gently, as residual moisture can encourage bacterial growth and worsen discomfort.
