Understanding Allergies for Dogs Scratching and Skin Issues

Dogs scratch for a variety of reasons, but allergies are a common culprit behind this annoying behavior. Allergies can cause intense itching, leading to skin irritation and even hair loss.

Atopic dermatitis is a type of allergy that affects many dogs, and it's often linked to environmental factors like pollen, dust mites, and mold. This allergy can cause red, itchy skin and ear infections.

Some breeds, such as West Highland White Terriers and Scottish Terriers, are more prone to atopic dermatitis due to their genetic makeup. These breeds may need extra attention from their owners to manage their allergies.

Flea allergy dermatitis is another common allergy that causes dogs to scratch excessively, and it's often linked to flea bites.

Allergies in dogs can be caused by a variety of factors.

Flea bites can trigger intense itchiness in dogs, and just a few bites can cause a reaction that lasts for two to three weeks.

Environmental allergens such as pollen from trees, grass, and weeds, mold spores, and dust mites can also cause allergies in dogs.

Dander, shed skin cells, can also be an allergen for dogs.

Food ingredients like beef, chicken, pork, corn, wheat, or soy can cause allergies in dogs.

The development and progression of allergies in dogs are determined by the accumulation of environmental allergen exposure over time, heredity, secondary bacterial infections, self-induced trauma, altered immune response, and impaired skin barrier function.

Most dogs begin to show their allergic signs between 1 and 3 years of age.

Here are some common allergens in dogs:

Dogs with allergies often exhibit itchy skin, which can lead to persistent scratching, biting, or licking of their skin.

Scratching is a common sign of allergies in dogs, and it's usually concentrated around the face, feet, and ears.

Licking can also be a sign of allergies, especially when it's excessive and targeted at specific areas like the paws.

Face rubbing is another common symptom, often accompanied by red skin and hair loss.

Red skin and hair loss are common signs of allergies in dogs, especially in areas like the ears, paws, and face.

Dogs with allergies may also experience gastrointestinal issues, such as vomiting or diarrhea, especially after eating specific foods.

Here are some common signs of allergies in dogs:

These signs can vary depending on the type of allergy your dog has, but knowing what to look for can help you identify the issue and get your dog the relief they need.

Diagnosing allergies in dogs can be a process of elimination, as symptoms can be similar to other skin conditions. A full medical examination, including a review of the dog's complete medical history, is essential.

A veterinarian may perform additional allergy testing, such as blood tests or skin prick tests, to determine the presence of an antibody called IgE to specific allergens. An increase in an allergen-specific IgE usually means there is an overreaction to that allergen in the body.

Intradermal testing (skin test) may also be done, where small amounts of test allergens are injected into the dog's skin, and the response is measured. Skin-testing often requires sedation and is typically performed by a board-certified veterinary dermatologist.

The cost of treating atopic dermatitis can vary depending on the severity of the disease and the types of treatment required. Some dogs may respond well to daily antihistamines, while others may require more expensive prescription medications, such as Cytopoint, which can cost between $35 to more than $130 per vial.

There is no actual cure for allergies, but finding ways to reduce or eliminate the symptoms will improve the overall quality of life.

Diagnosing canine allergies can be a challenging process, but with the right approach, it's possible to get to the bottom of what's causing your dog's skin issues. A comprehensive evaluation by a veterinarian is usually the first step.

Your veterinarian will take a detailed review of your dog's medical history, which can help identify any potential triggers. This may involve a physical examination to look for signs of skin allergies, such as redness, itching, or scratching.

In some cases, allergy tests may be necessary to determine the cause of the allergy. These tests can include blood tests, skin prick tests, or elimination diets to identify food allergies. Your veterinarian may also perform an intradermal test, where small amounts of test allergens are injected into your dog's skin to determine the cause of the allergy.

To determine which specific environmental allergens are triggering the allergy, your veterinarian may perform a skin test, which requires sedation and is typically performed by a board-certified veterinary dermatologist. This test can help identify the exact allergens causing the reaction.

Here are some criteria that may indicate the need for further testing:

Keep in mind that allergy testing should not be used to confirm that your pet has seasonal/environmental allergies, but to determine the specific things to which your dog is allergic.

Oral medications can be a useful treatment option for atopic dermatitis in dogs.

Some dogs respond well to a daily antihistamine, which can be a more affordable option compared to other prescription medications.

The cost of these medications can vary depending on the severity of the disease and the type of treatment required, averaging a couple of hundred dollars every month.

For some dogs, a daily antihistamine may be enough to manage their symptoms, but for others, more aggressive treatment may be necessary.

Cytopoint, an injection designed to help control itching in dogs with skin allergies, is a prescription-based medication with a cost that varies depending on factors such as the veterinarian, geographic location, and required dosage.

Atopic dermatitis is a lifelong condition, so it's essential to manage your dog's environment and daily health routines to minimize symptoms. This includes regular weekly baths to remove allergens attached to the skin.

Frequent visits to the veterinarian are necessary to determine how well your dog is responding to treatment, and it may take some trial and error to find the right treatment with minimal side effects.

Keeping the air fresh will minimize the risk of an allergic reaction, especially when inside. This can be achieved through the use of medical and home remedies.

Managing food allergies involves identifying and avoiding trigger foods, which can be done through a detailed approach including identification of allergens, monitoring during an elimination diet, reintroduction phase, and long-term management.

To prevent atopic dermatitis, regular use of flea prevention products and soothing shampoos can help relieve itching.

Here are some preventative strategies:

By following these steps and consulting with a veterinarian, you can help prevent skin issues in your dog and improve their quality of life.

There are several types of allergies that can cause a dog to scratch. Environmental Allergies are triggered by allergens found in a dog's surroundings, such as pollen, mold, dust mites, and grass.

Dogs can also suffer from Food Allergies, which are less common but can cause severe reactions. Common triggers include proteins like beef, chicken, dairy, or wheat.

Other types of allergies include Flea Allergy Dermatitis (FAD), where a dog is allergic to flea saliva, and Skin Allergies in Dogs (Atopic Dermatitis), which often result from environmental allergens and can lead to itchy skin and secondary skin infections.

Here are the different types of allergies in dogs:

Flea allergies are a common issue for dogs, with just one or two bites per week causing intense itching. An allergy to fleas is the most common skin disease seen in dogs.

The bite of a flea injects saliva that contains allergy-producing substances, which is believed to be the allergen that causes the itchiness. This is a severe allergic reaction, known as Flea Allergy Dermatitis (FAD).

Flea Allergy Dermatitis is a skin disease that requires strict flea control to eliminate symptoms. Treatment for flea allergy dermatitis is aimed at reducing the symptoms of itchy skin and irritation until the fleas are eliminated.

In severe cases, a dog's environment must be treated for fleas as well. This includes vacuuming thoroughly to remove eggs, larvae, and pupae, and discarding the vacuum bag.

To eliminate allergy symptoms in a flea-allergic dog, you can use highly effective flea control products and medications. Some popular options include topical liquids like Advantage, Revolution, or Vectra, and oral chews like Simparica, NexGard, or Comfortis.

Consult with your veterinarian to determine the best option for your dog. Oral preventions tend to be more effective than topical ones, but use caution – some oral preventions have flavorings your dog might be allergic to.

The most common areas affected by flea allergy dermatitis include the tail head, trunk, limbs, ears, axillary ("armpit"), inguinal ("groin") and perineal (genital/anal) areas.

Dogs can develop various types of allergies, each with its own set of triggers and symptoms. Environmental allergies are triggered by substances in a dog's surroundings, such as pollen, mold, dust mites, and grass.

Common environmental allergens include pollens, plant or animal fibers, dust mites, and mold spores. These allergens can be inhaled or absorbed through the skin.

Food allergies in dogs are less common than environmental allergies but can cause severe reactions. Common food triggers include proteins like beef, chicken, dairy, or wheat.

Flea Allergy Dermatitis (FAD) is a severe allergic reaction to flea bites, even a single flea bite can cause intense itching and discomfort.

Skin allergies, also known as atopic dermatitis, result in itchy skin, leading to scratching, licking, and biting at the skin. Contact allergies occur when a dog's skin reacts to direct contact with substances like certain fabrics, plastics, or cleaning products.

Here are the different types of allergies a dog can have:

Food allergies in dogs can be a real challenge to diagnose and treat. The most common food allergy for dogs is to a protein source in the diet.

Dogs can develop an allergy to a particular food at any point during their life, regardless of whether they have eaten these brands or types of foods in the past. This means that even if your dog has been eating the same food for years, they can still develop an allergy to it.

Symptoms of food allergies in dogs can be similar to those of seasonal/environmental allergies, and may also include gastrointestinal issues like diarrhea, vomiting, or an increased number of bowel movements per day.

Common culprits behind food allergies in dogs include beef, dairy, and wheat.

To determine if your dog has a food allergy, your veterinarian will likely recommend a hypoallergenic diet for at least 12 weeks. This special diet has limited ingredients with an uncommon protein source or is processed in a way that makes it less likely to cause allergic reactions.

Here are some common food allergens to be aware of:

Remember, over-the-counter foods are not recommended for a proper food trial, and treats, flavored medications, and human foods will also need to be eliminated during this trial period.

Bacterial (Staphylococcus) Hypersensitivity is an allergy to the normal bacterial flora of the skin.

This condition occurs more often in dogs with other conditions like flea allergy, hypothyroidism, and/or inhalant allergy.

It's an over-reactivity of the dog's immune system to the normal skin bacteria, Staphylococcus.

The condition is diagnosed through a bacterial culture looking for staphylococcus and a skin biopsy demonstrating unique changes in the blood vessels of the skin.

A skin biopsy is a medical procedure that helps identify the changes in the blood vessels of the skin.

Dogs can suffer from a range of allergies that cause them to scratch, and understanding these common allergens is key to identifying the root cause of your dog's discomfort.

Environmental allergens are a common trigger for dog skin allergies, and can include things like pollen, dust, and mold.

Flea allergy dermatitis, or FAD, is another common allergy that affects dogs, causing intense itching and scratching.

Food allergies can also cause skin issues in dogs, and can be triggered by a variety of ingredients, including beef, dairy, and wheat.

If you notice signs of allergies in your dog, it's essential to reach out to a veterinarian for a consultation and allergy testing. This can help pinpoint the specific allergen and allow for a more targeted approach to managing your dog's allergies.

Here are some common allergens that can affect dogs:

Treating atopic dermatitis in dogs can be costly, with some owners spending a couple of hundred dollars every month on prescription medications, allergy injections, and frequent vet visits.

The cost of treatment varies depending on the severity of the disease and the type of medication prescribed. For example, Cytopoint, an injection designed to control itching in dogs with skin allergies, can cost between $35 to more than $130 per vial, with larger dogs requiring multiple vials.

Topical therapy with medicated shampoos and conditioners can be a temporary solution for some dogs. These products often have a steroid or antihistamine base, and some may include a mild topical anesthetic or antimicrobial activity.

The cost of treating atopic dermatitis can add up quickly, making it essential for owners to work closely with their veterinarian to find the most effective and affordable treatment plan for their dog.
