From allergies to underlying health complications

Seeing or hearing your dog itching constantly is never nice for pet owners. It’s hard to know straight away what’s causing the itching, how severe it is and whether they have any other symptoms. Persistent itchiness in dogs is something we see regularly here at Knutsford Vets and it can be caused by any number of underlying conditions affecting both their skin and their general health. In this article we discuss what could be causing your dog to itch.

So, what could be causing your dog to itch?

There are a range of conditions that can cause your dog to itch. These can either be conditions or injuries localised to the area of the itching or they could be caused by a problem with their overall health. It’s also common for dogs to scratch when they are in pain or as a response to boredom or anxiety. Some potential causes could include: –

  • External Parasites
  • Allergies
  • Skin Diseases
  • Infections
  • Injuries or Pain

Now let’s take a look at each of these potential causes.

Parasites

Parasites, including fleas, mites and ticks are probably the most common cause of itching in dogs. Ticks can usually be spotted on the surface of the skin by inspecting beneath the coat and fur. Fleas are harder to spot and will largely go unnoticed until there is a large infestation. Mites are microscopic and require a vet to investigate skin and coat samples under a microscope. All of these require treatment of some kind, but luckily they are easily treatable.

Skin infection

Skin infections, including both fungal and bacterial infections are a common cause of itchiness in dogs. There are a number of different skin infections, these can either be caused by injury, poor coat maintenance or fleas. They may also occur naturally without any noticeable external factors contributing.

Allergies

Allergies are another common cause of itching in pets. This can include food allergies, environmental allergies (such as allergies to mould or pollen) or a reaction to soap or shampoo, also known as contact dermatitis. This will often present as general itchiness and your dog may scratch all over their body.

Injury or Pain

If your dog is injured, cut or in some kind of pain that is localised to a specific area, itching or pawing at the area is a common response. Whenever dogs feel uncomfortable they will often paw, scratch or bite the area which can be confused for itchiness. Inspect the surface of the skin any noticeable signs of injury, such as cuts or debris stuck in the skin. You should then rub the area affected to see if they show signs of discomfort that could be caused by injury or pain to bones, muscles or internal organs.

A visit to the vets is always the best way to get to the bottom of your pet’s itching

How can I find the cause of my dog’s itching?

When it comes to finding out what’s causing your dog’s itching, the best place to start is always your local vets. Obviously the level and severity of any itching will determine the length of time to wait before visiting.

If the itching is severe, constant and persistent and begins suddenly wait no longer than a couple of days. For itching that is less persistent, but continues over a few days it’s probably worth waiting a week. If in any doubt always contact your local vet and discuss the symptoms, a consultation will only cost a small amount, but it could put to an end any discomfort or identify a serious illness.

Initial Examination

If you visit your local vets they will begin by observing the skin itself, before asking a range of questions about the behaviour of your pet in the days when the skin issue occurred. This will help them determine if it’s an issue with the skin itself or whether the itchiness is a symptom of a more general health issue.

Diagnostic Testing

The way in which we diagnose the cause of your pet’s itching will vary depending on what we believe to be a potential cause. Some of the tests that your vet can do include: –

  • Swabs – these can be taken from skin and from the ear canal for examination for the presence of bacterial infections in a laboratory setting.
  • Microscope analysis – a vet can take hair plucks and skin scrapes to investigate for the presence of fungal infections.
  • Hair pluck analysis – hair plucks can help identify the presence of fungal infections in a laboratory.
  • Skin biopsies – a section of skin can be taken from the pet for further analysis. This can help identify allergies and immune conditions affecting the skin.
  • Allergy testing – if all other issues have been ruled out and the vet believes the itchiness is caused by a food allergy, you may be required to keep a food diary or restrict items of food to eliminate potential causes.
