Dog Itching

Often the first sign your pet has a skin condition is non-stop scratching. Then comes the biting or gnawing, the inability to sit still or seeming unsettled. Your pet may scratch so much they start to go bald. You've tried every shampoo, conditioner and cream under the sun, but then your vet asks, "what are you feeding them?". You might be thinking, "how could what I feed my pet have anything to do with a skin condition?", but food allergies in pets that cause skin irritation are not that uncommon.

My Pet Won't Stop Itching, Should I See A Vet?

Of course, there are many causes of skin conditions in cats and dogs. If your pet has a skin irritation that is accompanied by sores, a rash, hair loss, or ear inflammation, it is important for them to be assessed by a veterinarian so that the cause of their problem can be determined.

What Causes Itchy Skin?

Some of the most common causes of skin irritations in cats and dogs include:

  • Food allergies or adverse food reactions
  • Parasites or infections (fleas, bacteria, ringworm, etc)
  • Environmental allergies (pollen, dust mites, etc)
  • Endocrine or autoimmune disorders

How Will My Vet Determine What Is Making My Pet Itchy?

Your vet may utilise one or many procedures to determine the underlying cause. A skin scraping, hair pluck, tape test, food trial, blood sample or biopsy are just some of the methods of identifying a reason for your pets itching.

What Causes Food Allergies?

When your pet has a food allergy, their immune system mistakenly reacts to proteins found in meats such as beef, fish or lamb. In an animal without a food allergy, these proteins do not normally trouble the immune system, which when working normally, protects your pet from viruses and bacteria. In a dog with a food allergy however, an immune response is triggered when the food proteins are detected, leading to skin irritation and redness, itching, and sometimes vomiting and diarrhoea.

How Are Foods For Pets With Allergies Different>

In foods that have been specially formulated for pets with food allergies, the manufacturer will use a hydrolysed protein source. A hydrolysed protein is simply one that has been cut down into a smaller molecular size. The smaller size prevents the protein from triggering an immune response as the immune system no longer sees the smaller proteins as a threat.
