Does Your Dog Have a Flea Allergy?

What Is Flea Allergy Dermatitis in Dogs?

Fleas take their first blood meal on the host (your dog) within minutes of contact.² When a flea feeds, it injects its saliva into your dogs skin. This saliva contains enzymes, peptides, and amino acids. It also contains histamine-like compounds that trigger a release from the dogs immune system.

Flea saliva can cause an inflammatory reaction in animals that are sensitive to it. Some dogs have an immediate hypersensitivity to it within 15 minutes, while others have a delayed reaction that takes 24-48 hours.

Dogs with atopic dermatitis are more likely predisposed to developing flea allergy dermatitis (FAD).¹

What if I Dont See Fleas on My Dog?

Just because you dont see the fleas, it does not mean they arent there.

A common misconception is that fleas are only a concern during warmer months. This is not true. Another misconception is that fleas cant come inside your house. Fleas can live indoors as eggs, larvae, and pupae, and pets and humans can also bring fleas inside.

Signs of a Flea Allergy in Dogs

You may not see the fleas right away, but you will see the evidence of the allergic reaction. Even one flea bite can cause this allergic reaction.

When dogs feel flea bites, they often chew and bite at their rear by their tail and/or jump up from a resting position. If you see itching in your dog, and it leads to hair loss on the middle of the back to the tail base, you need to think flea allergy dermatitis. The hair loss can spread all over the body, up to the head and neck if left untreated.

When a dog scratches, licks, and chews, it breaks the skin barrier and can cause open sores and scabs. The licking and chewing can also cause ongoing moisture that can lead to yeast and bacterial infections.

How Does the Vet Diagnose a Flea Allergy in Dogs?

It is important to get a true diagnosis when a dog is itching severely.

Your vet will first look for any evidence of fleas or flea dirt (which is the flea excrement), sometimes using a fine-tooth comb.

It is common that a pet parent may not see the fleas at home on the pet, but veterinary staff are trained flea detectives who work hard to find them.

Tests can also be done to determine the underlying cause of the allergic reaction. Vets use blood tests and skin tests for flea allergies.

Skin testing, called intradermal testing, is usually performed by a veterinary dermatologist. A wheal (bump on the skin) forms on the skin, usually within 15-20 minutes of injected a small amount of an allergen into the skin.3

Blood testing can also be done in most general veterinary practices to test the IgE directed against the flea-specific salivary antigens.

Diagnosing the Secondary Skin Infections in Dogs

There is often a secondary infection that develops on a dogs skin with FAD. Your vet can use cytology to diagnose any secondary skin infections.

Cutaneous cytology is a valuable diagnostic tool. Using a piece of tape to collect a surface sample from a skin lesion helps determine the type of microbial population as well as the inflammatory component present.⁴

It is quick and inexpensive. This helps guide the doctor to prescribe the most appropriate and effective treatment for the patient.

How Do You Treat Flea Allergy Dermatitis in Dogs?

The number one priority in FAD treatment is to kill the fleas! This means to kill them not only on your dog, but on all pets in the household and killing fleas in the environment.

Oral Flea Medications

Oral flea medications are going to provide the quickest demise of the fleas.

You can use a product containing Spinosad to kill all fleas on your dog within 30-60 minutes to give the quickest relief. Then you can follow up with a product that lasts 30-90 days.

Once the fleas are dead, it is a good idea to bathe the dog to get off all of the dead bugs and their excrement. You can get a medicated shampoo prescribed by your vet to soothe the skin, or you can find over-the-counter dog shampoos that contain oatmeal and pramoxine to help soothe the itch.

Skin Treatment

After the fleas are eradicated, you still need to treat the skin irritation caused by the allergic dermatitis.

In mild cases, you can treat your dog with Benadryl at home to stop the allergic reaction and provide relief from the itch.

Always check with your veterinarian for dosing instructions and to make sure this medication is safe for your pet.

Most dogs with FAD need more help, and you can talk to your veterinarian about the need for steroids or other allergy meds such as Apoquel or Cytopoint.

How to Prevent Flea Allergies in Dogs

As the saying goes, an ounce of prevention goes a long way. Preventing, reducing, and eliminating flea infestations is crucial to preventing recurring FAD.

Treat the Environment

Just treating your pet without treating the environment is only 50% of the problem. Indoor flea eradication measures include vacuuming (carpets, cushioned furniture, cracks and crevices on floors, and baseboards) and washing pet bedding in hot soapy water.

Treat Your Yard

Outdoor areas need attention, such as shaded areas around the house or your dogs kennel or favorite sleeping area. You can use premise sprays for fleas indoors and out. For both the house and yard, you may need to contact an exterminator for the best method of flea removal.

Use Monthly Flea and Tick Preventatives

There are many flea prevention products on the market. Work with your veterinarian to pick the one that is best for your dog.

The oral medications in the isoxazoline category have been the most recent group that has been extremely effective and safe for most dogs. Talk to your vet to make sure your dog doesnt have any contraindications such as seizures.

If you keep the flea population under control, you can spare your pet pain and suffering. It can take three months to rid your house of an infestation. It is time-consuming and expensive.

Prevent what you can to keep your dog flea-free!

Dog Hives

What Are Dog Hives?

Hives (also referred to as urticaria) are areas of the skin that appear reddened and raised. Just as with humans, hives can be very itchy for your dog. Theyre a sign that an allergy is causing the immune system to overreact.

Hives can appear very quicklyand disappear just as quickly. The raised red area of the skin is referred to as a wheal, and it can appear anywhere from a few minutes to hours after exposure to an allergen. Wheals can appear anywhere on your dogs body, but theyre usually found on the head, neck, back, stomach, and legs.

In mild cases, the hives will generally disappear within 12-48 hours after contact with the allergen. However, because of the risk that the reaction can worsen to dangerous swelling of your dogs airways or a serious allergic reaction called anaphylaxis, you should seek out treatment any time you see hives on your dog. This is especially true for hives that occur on the face or around the throat, which can lead to dangerous swelling and possible blockage of the airways.

Symptoms of Dog Hives

Red raised areas of skin called wheals, which can occur anywhere (including mucous membranes) but are most commonly seen on the head, neck, back, abdomen, and legs
Intense itching
Excessive drooling if the mouth is swollen
Swelling (angioedema), which is particularly concerning when it involves the face and respiratory system and can have severe and life-threatening consequences

Causes of Dog Hives

The allergen that causes the hives may be environmental, chemical, or dietary. Any allergen your dog is sensitive can also lead to hives. Common causes include:

Insects bites, chemical contact, and medications are the most common.

How Vets Diagnose Hives

Your vet will closely examine your dog to locate the distinctive wheals associated with hives. Wheals typically have hair on them, and may appear in clusters. Beyond the physical examination, other parts of the diagnosis include:

Any history you are able to provide; be as thorough as you can in describing allergens your dog might have come into contact with and when and where you first saw the hives
Your dogs response to treatment

Treatment for Dog Hives

Dogs with hives usually respond quickly to treatment, which may include:

At-home treatments may include:

Cold compresses over the hives or swollen areas to give relief from itching
Antihistamines, but only under the supervision of your vet

Management of Dog Hives

Work with your vet to determine the cause of the hives, using both your dogs health history and history of exposure to allergens. Depending on the cause and the frequency, your vet may recommend:

Allergy testing to confirm environmental allergens
Immunotherapy treatment to desensitize your dog to specific allergens
A food trial to find ingredients that cause a reaction and develop specific dietary recommendations

Identifying Ant Bites on Dogs

Ant bites can be a common problem for dogs, especially during the summer months. Its important to know how to identify ant bites on your dog so that you can take the appropriate action to treat them. In this section, well discuss how to recognize bite marks and observe your dogs behavior.

Recognizing Bite Marks

Ant bites on dogs can look similar to other insect bites, such as flea bites or mosquito bites. However, there are a few key differences to look out for. Ant bites are usually red and swollen and may have a small white center. They can also be painful to the touch.

If you notice your dog scratching or licking a certain area excessively, its possible that they have been bitten by ants. Check the area for redness, swelling, or any signs of irritation.

Ants are among the most prolific insects, with an estimated population of 10 to 100 quadrillion and more than 12,000 different species. So, knowing how different ant bites look can be a stretch. However, imported red fire ant stings are among the most commonly studied.

Overall, ant bite signs include:

Red or pink raised bumps;
Swelling;
Itching;
Pustules;
Inflammation; and
Hives.

Observing Dogs Behavior

In addition to checking for bite marks, its important to observe your dogs behavior. Ant bites can be painful and uncomfortable and may cause your dog to act differently than usual. Some signs to look out for include:

Restlessness or agitation;
Excessive scratching, licking, or biting;
Whimpering or crying;
Loss of appetite; and
Swelling or redness in the affected area.

If you notice any of these symptoms, its important to take your dog to the vet for treatment. In some cases, ant bites can lead to more serious health problems, such as an allergic reaction or infection.

Research shows that most fatalities after ant bites result from immediate hypersensitivity to the venom. Ants release formic acid after they bite, which some dogs react to severely. The same study showed that 20 stings per kg can be fatal even to a non-allergic dog.

By knowing how to identify ant bites on your dog, you can take the necessary steps to treat them and keep your furry friend healthy and happy.

Immediate Actions After Ant Bites

If your dog gets bitten by ants, there are a few immediate actions that you can take to help reduce the discomfort and prevent further bites.

Removing the Dog from the Area

The first thing you should do is remove your dog from the area where they were bitten. This will help prevent them from getting bitten again and also reduce the risk of the ants attacking you. If the ants are still present, try to remove them from the area as well.

Cleaning the Bite Marks

After removing your dog from the area, inspect the bite marks. Clean the area with soap and water to help prevent infection.

Cold compress

Apply a cold compress (a clean cloth or ice pack wrapped in a towel) to the bite site for 10-15 minutes.

Over-the-Counter Remedies

Some pet-safe over-the-counter antihistamine creams or ointments can help alleviate itching and irritation. Have your vets recommendation beforehand if you keep these ointments at home.

If the bite marks are severe or your dog is showing signs of an allergic reaction, seek veterinary attention immediately.

Remember, prevention is key when it comes to ant bites on dogs. Keep your dog away from areas where ants are present, and always supervise them when they are outside. If you notice a large number of ants in your yard, consider contacting a pest control professional to help eliminate the problem.

Medical Treatments for Ant Bites

If your dog has been bitten by ants, there are several medical treatments that can help alleviate the symptoms. In this section, we will discuss two types of medical treatments for ant bites on dogs: topical ointments and oral medications.

Topical Ointments

Topical ointments are a common treatment for ant bites on dogs. These ointments can help reduce pain, itching, and swelling. Some of the most effective topical ointments for ant bites on dogs include:

Hydrocortisone cream: This cream can help reduce itching and inflammation caused by ant bites.
Calamine lotion: This lotion can help reduce itching and soothe the skin. However, it contains zinc oxide that can be toxic to dogs when licked. Consult your vet for this medication.
Aloe vera gel: This gel can help reduce pain and inflammation caused by ant bites.

When applying topical ointments, it is important to follow the instructions carefully. Be sure to clean the affected area before applying the ointment, and avoid getting the ointment in your dogs eyes or mouth.

Oral Medications

In some cases, oral medications may be necessary to treat ant bites on dogs. These medications can help reduce pain, inflammation, and allergic reactions caused by ant bites. Some of the most common oral medications used to treat ant bites on dogs include:

Antihistamines: These medications can help reduce itching, swelling, and hives caused by ant bites.
Pain relievers: Pain relievers such as Carprofen (Novox or Rimadyl) and Deracoxib (Deramaxx) can help reduce pain caused by ant bites.
Steroids: In severe cases, steroids may be necessary to reduce inflammation and allergic reactions caused by ant bites.

A study on 10 dogs showed that venom immunotherapy (98% efficiency in humans) is effective for dogs with extreme reactions to ant stings and bites.

If you are unsure which oral medication to use, it is important to consult with your veterinarian. They can help determine the best course of treatment for your dog based on their age, weight, and overall health.

Home Remedies for Ant Bites

If your dog has been bitten by ants, there are several home remedies that you can use to alleviate their pain and discomfort. Here are two of the most effective remedies:

Cold Compress

A cold compress can help to reduce swelling and pain caused by ant bites. To make a cold compress, wrap a few ice cubes in a towel or use a cold pack and apply it to the affected area for 10 to 15 minutes. Repeat this process every few hours as needed.

Aloe Vera Application
