Skin allergies are common problems among dogs and cats, manifesting themselves in the form of skin problems. Help protect your pet and learn more.

Has your dog ever scratched and bit at their skin so much that it bled? If so, we bet your pet was miserable. Skin allergies are common problems among dogs and cats. We often forget that sometimes, just as with humans, our pets can suffer from allergies. But instead of sniffing and wheezing, dogs and cats often demonstrate their allergies in the form of skin problems. Here's how to help your pet deal with dog or cat dermatitis.

Numerous outside problems can cause your pet to have an allergic reaction including fleas, food allergies, and even the things that cause you to sneeze and sniffle like pollen or dust mites. With pet foods, common ingredients can sometimes cause skin allergies including corn, dairy products, soy, beef, and preservatives or other chemical additives. When pets react to the presence of fleas, they are typically allergic to the fleaโ€™s saliva.

Signs of Allergies

With skin allergies, pets do a lot of scratching, biting, and licking of parts of their bodies. If fleas are the cause, you might see the presence of flea dirt, the tiny blood spots left behind by the little parasites. Sometimes your pet's hair will fall out or will be stained dark from blood or appear greasy from constant rubbing. The skin may also be inflamed and red, sometimes with discharge. Skin inside the ears may be inflamed. Scabs may be present from constant scratching and bleeding. Some breeds, like Westies, are more prone to particular types of skin allergies.

Diagnosis and Treatment

If your dog or cat shows these signs, your veterinarian can perform several tests to determine the cause. Depending on the signs, testing can include skin scrapings to see if the cause is a type of parasite, skin swabs to view under the microscope for parasites, a fecal exam to see if the cause is an internal parasite, intradermal allergy skin tests, and blood analysis, among others.

For some pets, just the elimination of the offending allergen can solve the problem. For some, a change in food as or the addition of fatty acid supplements may be what's needed.

Some pets may require medical treatment such as anti-inflammatories, antihistamines, antibiotics (like Clavamox), or allergy shots. If fleas are the cause, removal of the fleas with medication will solve the problem. For fungal infections, medicated shampoo solves the problem. And, finally, topical medications can help treat the irritation.

Keep in mind that often the skin allergy can be a chronic problem that needs to be continually treated. But if you recognize the signs early enough before your pet really suffers from inflammation and, with the help of your veterinarian, establish the cause of your petโ€™s allergies, you can keep them happy and comfortable with routine maintenance.

Dandruff and Flaky Skin in Dogs and Cats

Pet dander, or dandruff, occurs naturally as the body sheds skin cells and replaces them with new ones. And like humans, dogs and cats can develop a buildup of dandruff and flaking when their skin is dry or lacking in nutrients.

Dandruff and flaky skin in pets can be caused by a variety of reasons, but it most commonly occurs because of diet and grooming issues. Pets residing in dry or cold climates may also develop flaky skin due to the air conditions.

Pet dandruff can also be a symptom of a larger medical issue that needs to be addressed by a veterinarian. Deficiencies and diseases associated with flaky skin may cause your pet discomfort and even signify poor health.

Causes of Flaky Skin

The most common causes of pet dandruff are associated with grooming, climate, and nutrition. Most of these issues can easily be reversed, but flaky skin can also be linked to more serious medical concerns, such as hormonal diseases, allergies, or parasites like fleas and mites. Chronic flaky skin or dandruff that is accompanied by other severe symptoms should be examined by a veterinarian.

Symptoms of Flaky Skin

Most pet parents will recognize flaky skin as white flecks on their pet's fur, much like human dandruff. Other symptoms that may show up when a pet has excessive dandruff include dry, scaly skin, irritation, infection, and cracks or sores in the skin. These symptoms will often be accompanied by your pet scratching, biting, and licking their coat.

Treatment of Flaky Skin

Depending on the underlying cause, flaky skin can be treated in a number of ways. Dandruff will likely go away with a more balanced grooming schedule, switching shampoos, and adjusting bathing frequency. If nutritional deficiencies are the cause of pet dandruff, then a simple change in diet can relieve and eliminate symptoms quickly.
