The Surprising Link Between Your Dog’s Food Allergies and Chronic Itching

10 minutes

It's heartbreaking for any pup parent to see their dog struggle with skin issues. The constant scratching, itching, and visible soreness can be difficult to watch – and you just want to help them feel better.

Skin issues in dogs are often caused by parasites, infections, and environmental allergies. But what about food allergies? Though relatively rare, they can also cause chronic itching and skin problems for your pup. So, if your dog has persistent skin issues, it's worth considering food allergies as a potential cause.

What Causes Food Allergies in Dogs?

Just like humans, dogs can be allergic to certain food ingredients. Common allergens include beef, dairy, chicken, wheat, and lamb. If your pup ingests something they're allergic to, their bodies will react with immune system responses. This reaction can cause itchy skin and other uncomfortable symptoms.

What Are the Signs of Food Allergies in Dogs?

Food allergies in dogs can cause a wide range of symptoms, but skin issues are especially common. Here are a few signs to look out for:

  • Constant itching or scratching

  • Redness or scabbing

  • Hair loss, thinning fur, or bald patches

  • Paw chewing and redness around the paws

Other signs of food allergies in dogs include digestive issues, such as vomiting and diarrhoea. Your dog may also experience swelling, especially around the face, mouth, eyes, and ears.

Although allergies are one of the main causes of itchy skin in dogs, food allergies are fairly uncommon. In fact, food allergies are found in only a small percentage of the global canine population. This means that other causes, like parasites and infections, are much more likely.

Taking your dog for a check-up is the best way to get to the bottom of their skin problems. Your vet will be able to determine if they have food allergies or another underlying issue.

How Are Food Allergies in Dogs Diagnosed?

At a veterinary appointment, your vet will likely take a few different steps to determine if your dog has food allergies. First, they'll ask about your pup's diet and other relevant information – such as their age, environment, and symptom history.

Next, your vet will physically examine your dog to rule out other issues like parasites and infections. They may also run tests like blood work, skin scrapings, and cytology tests.

In certain cases, your vet may want to run a food elimination trial to check for food allergies. This is the only reliable way to confirm a food allergy and identify which specific ingredient(s) are involved. Food elimination trials involve following a scientifically proven protocol over several weeks. It's essential to follow your vet's instructions and work closely with them to ensure the trial goes smoothly.

How Are Food Allergies in Dogs Treated

Once your vet has confirmed that your pup is suffering from food allergies, it's time for a treatment plan. Skin issues caused by food allergies can be managed in several ways, but the aim is to keep your pup comfortable and itch-free.

Here are a few of the most common treatments for skin issues in dogs with food allergies:

  • Dietary changes.

Your vet may suggest a hypoallergenic diet for your dog to minimise their exposure to allergens. This could be a vet-prescribed commercial food or homemade meals that exclude certain ingredients.

  • Supplements.

Omega fatty acids and other supplements can help your pup's skin health from the inside out.

Many medications can help reduce itching. Your vet may also recommend topical creams, shampoos, and other products to soothe your dog's skin.
  • Allergy medications.

Vet-prescribed medications can help reduce your pup's itching and related symptoms.

  • Skin treatments.

Your vet may also recommend topical creams, shampoos, and other products to soothe your dog's skin.
