Allergies in dogs

Allergies in dogs are more common than many pet owners realise and can affect dogs of all breeds and ages. Just like in humans, allergies in dogs are an overreaction of the immune system to foreign substances, known as allergens. The body’s immune system identifies these substances as harmful. It triggers a response ranging from mild symptoms, like sneezing and itchy skin, to more severe reactions, such as anaphylaxis, which can be life-threatening. Fortunately, most allergies in dogs are not as extreme as those in humans. However, they can still cause significant discomfort and distress in your pet.

Common Signs of Allergies in Dogs

Recognising that your dog is suffering from allergies can be difficult, as the symptoms often overlap with other health issues. However, several common signs could indicate an allergic reaction in pets, especially if the symptoms persist or worsen over time.

Here are some symptoms to watch for:

  • Itchy, inflamed skin
  • Redness or rash, particularly on paws, ears, face, and tummy
  • Excessive licking or chewing
  • Vomiting or diarrhoea (in food allergies)
  • Sore or swollen ears
  • Sneezing and watery eyes (for environmental allergies)

If you notice any of these clinical signs or you think your pet may have allergies please consult a vet.

Types of Dog Allergies

Dog allergies generally fall into three categories: flea, environmental, and food.

Flea allergies in dogs are a reaction to the saliva of fleas. Symptoms include itching, redness, rashes, and hair loss, especially on the paws, ears, belly, and face. If your dog has a flea allergy, treating and preventing flea infestations is the best protection for your pet. Please speak with you vet for treatment of the fleas and any related skin issues.

Environmental allergies are commonly caused by pollen, mould, dust mites, and household cleaning products. This is the most common type of allergy seen in dogs. These allergies can be seasonal, often worsening during specific times of the year. Typical symptoms include persistent itching, inflammation, and skin irritation, particularly around the ears, paws, and eyes.

Food allergies can develop at any time, even if your dog has been eating the same food for years. Common triggers are protein, wheat or dairy. Symptoms can include itchy skin, rashes, digestive upset (vomiting or diarrhoea), and excessive gas. In severe cases, food allergies can significantly affect a dog’s health and quality of life.

If you suspect your dog has allergies, it is vital to seek advice from a veterinarian for proper diagnosis and treatment. When left untreated, allergies can lead to chronic discomfort and even secondary infections.
