Why is my dog so itchy?

Flea and Flea Allergy Dermatitis

 

One common cause of itching in pets is a hypersensitivity to flea bites, also known as flea allergy dermatitis. It doesn’t take many fleas to whip your pet into a scratching and grooming frenzy, but the condition isn’t always easy to identify and is frequently mistaken for a rash. Often, you won’t see any fleas because they spend most of their lives off of your pet.

Your veterinarian may want to use a flea comb to look for the little critters or their “dirt” (excrement). If there are any fleas, your veterinarian will put your pet on a flea preventative and perform further tests to rule out other causes of itch.

If your pet is diagnosed with flea allergy dermatitis, your veterinarian will dispense medication to control the itch and will recommend an aggressive flea control plan for your pet, his environment, and other pets in the house.

Prevention is simple: keep your pet from getting fleas! Talk to your veterinarian about the best flea prevention methods for your pet.

 

SIGNS AND SYMPTOMS OF FLEA ALLERGY

  • Hair loss, especially along the back and hind end
  • Chewing and biting at the tail, hind end, and hind legs
  • Skin damage due to a lot of scratching and licking

 

It could be mites!

Fleas aren’t the only parasites that like to live on your pet. Mites can also be a pain, though they are a whole lot smaller. The two most common types of mites – sarcoptes and demodex – can cause secondary skin infections in addition to itching.

And while sarcoptes mites tend to affect the ears, elbows, and chest of a pet, demodex mites are less particular and can appear anywhere on a pet’s body. If your veterinarian suspects that your pet has mites, he or she will perform skin scrapings to look at under a microscope. However, sometimes this isn’t enough – mites are so small, they can’t always be detected, so your veterinarian may choose to treat your pet based on suspicion of mites.

One thing to note: if your pet has highly-contagious sarcoptes mites, all pets in the household need to be treated.

 

Treatment for mites includes:

 

  • Shampoos
  • Topical preventives
  • Sanitation, especially cleaning and vacuuming bedding
  • Medications to control the itch and treat secondary skin infections

 

Bacterial and Fungal infections

 

An itch has to be scratched, but all that increased scratching by your pet damages the skin, which can result in bacterial and fungal infections as secondary conditions to itching.

Common signs of infection include inflamed, reddened skin, areas of hair loss, and ear infections. These infections also often cause your pet to have an unpleasant odour. In order to diagnose a bacterial or fungal infection, your veterinarian will collect samples for culture or examination under a microscope.

 

Food allergies

 

Tiny organisms aren’t the only thing that can give your pet allergies. Food can also cause problems, and food allergies often arise out of the blue. When a pet becomes sensitive to food – often a protein like chicken, beef, or lamb – that he used to easily tolerate, food allergies could be the culprit. This can happen at any time, even if a pet’s diet remains unchanged. It’s not always easy to distinguish food allergies from a simple upset stomach or other allergic conditions, but if the symptoms persist, food allergies may be the cause.

Food allergies cause itching, stomach problems, vomiting, weight loss, skin and ear infections, lethargy and decreased activity

If food allergies are suspected, your veterinarian will perform a physical exam and ask for a detailed history of your pet’s food intake. But the only way to diagnose a food allergy is through hypoallergenic diet trial to see if it reduces your pet’s symptoms. The diet shouldn’t contain anything your pet has recently eaten and he won’t be able to eat any treats or supplements unless approved by your veterinarian.

The only treatment for food allergy is avoidance. This may seem like common sense – don’t feed your pet foods to which he is allergic. But it’s not always easy to identify foods that are both nutritionally balanced and devoid of problem ingredients for your pet. Your veterinarian will help guide you and your pet for long-term diet management.

Atopic Dermatitis

 

Sometimes, the answer to your pet’s itching problem is “none of the above.” If your pet continues to itch for no apparent reason, there’s a chance he has atopic dermatitis. Similar to “hay fever” in people, atopic dermatitis is caused by a reaction to environmental allergens such as pollen, mould spores, or plant fibres. If your pet is diagnosed with atopic dermatitis, allergy testing and allergen-specific immuno-therapy may be the best option from your pet.

If your pet has been diagnosed with Atopic Dermatitis, you need to ensure that you remain patient and take medications as recommended by your veterinarian as per the dose and duration.

Fortunately, there are medications that act on the root cause of Atopic Dermatitis. It is important to weigh short term cost of treatment with long term gain in terms of benefits.
