What Causes Flea Allergy Dermatitis In Dogs

Fleas inject saliva that contains a variety of histamine-like compounds, enzymes, polypeptides, and amino acids. They do so while feeding.

Dogs can develop either immediate or delayed reactions, or both.

Dogs who are exposed continuously to flea bites have low levels of circulating antibodies in their bodies from the fleas saliva. They either do not develop skin reactions or develop them later and to a considerably reduced degree.

In hypersensitive dogs flea allergy dermatitis can be intense and may show up all over the body.

  • lower back
  • tailhead

The rump and tailhead areas are typically the first, most evident, areas affected.

Flea Allergy Dermatitis In Dogs And Cats: Symptoms Treatment And Prevention

Flea bites expose pets to flea saliva which some pets become allergic to over time. This allergic reaction is known as flea allergy dermatitis, or FAD.

FAD is an allergic skin condition that mostly affects pets aged over one year and commonly occurs in dogs and cats with underlying skin diseases like atopic dermatitis.1, 2 Pets with FAD can damage their skin by constantly scratching, biting or licking, and this damage can lead to secondary infection.

Can Fleas Become Resistant To Flea Products

If flea control depends on flea products, and these have been used for many years, do fleas develop resistance? Hypothetically, they could. âIn theory, resistance would be more likely with the products that have been on the market longer,â Dr. Oldenhoff says. âFor this reason, I have recently been recommending the new oral flea and tick preventives,â among them, Nexguard, Bravecto and Simparica .

Dr. Oldenhoff recommends these products because they are virtually foolproof. You donât have worries like: âDid I put the full vial on my dog? Did I get it right on the skin? Did I bathe my dog too quickly, thus washing it off?â

A dogâs perceived resistance to flea products may also be the result of their exposure to feral cats and urban wildlife, or to other pets in the household otherwise, the infestation will continue.

Flea allergy dermatitis occurs as a result of flea bites and may develop in canines that are more sensitive. The flea allergy dermatitis will manifest through swelling, and will cause itchiness, so the dog will lick and chew the affected area. This will lead to additional irritation, which should be treated to prevent complications.

Clinical Findings Of Flea Allergy Dermatitis In Dogs And Cats

Flea dermatitis...

Clinical signs associated with FAD are variable and depend on frequency of flea exposure, duration of disease, presence of secondary or other concurrent skin disease, extent of hypersensitivity, and effects of previous or current treatment. Nonallergic animals may have few clinical signs other than occasional scratching due to annoyance caused by flea bites. Those patients that are allergic will typically have a dermatitis characterized by pruritus.

In dogs, the pruritus associated with FAD can be intense and may manifest over the entire body. Classic clinical signs are papulocrustous lesions distributed on the lower back, tailhead, and caudal and inner thighs. Dogs may be particularly sensitive in the flanks, caudal and medial thighs, ventral abdomen, lower back, neck, and ears. Affected dogs are likely to be restless and uncomfortable, spending much time scratching, licking, rubbing, chewing, and even nibbling at the skin. Hair may be stained brown from the licking and is often broken off. Common secondary lesions include areas of alopecia, erythema, hyperpigmented skin, scaling, papules, and broken papules covered with reddish brown crusts. The rump and tailhead areas are typically the first, most evident, areas affected. As FAD progresses and becomes chronic, the areas become alopecic, lichenified, and hyperpigmented, and secondary bacterial and yeast infections occur.

What Is Flea Allergy Dermatitis

Flea allergy dermatitis is an allergy to flea bites and its actually super common in dogs.

Flea allergy dermatitis is one of the most common allergies in our dogs and cats, Dr. Oberkirchner told The Dodo. If this animal gets bitten by just one or very few fleas, it will become severely itchy and the downward spiral is then allowed to begin.

An allergic reaction to fleas is really uncomfortable for pets, and its far more annoying than a normal reaction to a flea bite .

Dogs and cats who suffer from FAD typically are severely itchy and often require veterinary care to help them become and stay comfortable, Dr. Oberkirchner said.

Oftentimes, it only takes one flea to cause a reaction, which means you may notice a reaction but not see fleas or flea dirt on your dog. Even if your other pets are totally fine and you cant spot a single flea in your house, its still very possible your dog has a flea allergy.

It is important to know that FAD is not the same as a flea infestation. If someone has a flea infestation in their home, most animals will itch somewhat, and one can often see fleas on the animal or in their environment, Dr. Oberkirchner said.

This is in stark contrast to FAD, she added. In FAD, it is often a single animal that is affected and, typically, the owners have never seen fleas on their pet or in their environment.

Diagnosing Flea Allergies In Cats

Diagnosing cat flea allergy is easier if you find fleas or flea dirt, but, too often, you dont find them on an allergic cat. The cat is grooming them off so rapidly, you dont find any evidence. The diagnosis may be made by seeing how the cat responds to appropriate treatment.

Often the biggest challenge veterinarians have is convincing the cat parent that fleas can be the problem. Fleas arent seen so its difficult to believe they are there. Just one flea can cause intense itching for up to 3 months.

The cat parent may also be treating the cat for fleas, however, not all flea prevention works 100%, and they kill the flea in different ways. Some repel, some kill on contact, and some the flea must bite.

To complicate things further, your cat may have other allergies or conditions that also cause itchy skin. In these cases, you may need to treat for fleas and see how much relief your cat has. If you still have an itchy cat, you will need to look for other causes.

I Was Told That My Dog Has Flea Allergy Dermatitis But I Have Never Seen A Flea On Him How Can He Have Flea Allergy Dermatitis

Is Flea Allergy Dermatitis A Problem for your pet?

Flea allergy dermatitis is a leading cause of allergic reactions in dogs. In an allergic reaction, the bodys immune system overreacts or is hypersensitive to a substance that is normally harmless.

FAD is a common cause of itching in dogs. Adult fleas must bite a dog and obtain a blood meal in order to reproduce. Fleas typically do not remain on the dog except for the minutes to hours when they are feeding. This is why dog owners often do not see live fleas on their dog unless there is a severe flea infestation in their immediate environment. When fleas feed, they inject a small amount of saliva into the skin. It is the antigens or proteins in the saliva that cause an intensely itchy response to sensitive dogs.

“A single fleabite can cause itching for days.”

Dogs with FAD do not have to be infested with fleas to be itchy. In fact, a single fleabite can cause itching for several days.

How Can Fad Manifest In Pets

Itching can manifest in a number of ways, including scratching, licking , biting, chewing, and rubbing the body along the ground.

Allergic skin is normally red and inflamed, which raises its temperature and humidity and creates the perfect environment for bacterial and fungal growth. Skin infections are common secondary to allergic skin disease. Most of the damage in FAD is caused by self-trauma, the animal scratching itself.

” with FAD usually have very few fleas, but severely self-traumatized due to the intense itching.”

Dogs with FAD tend to suffer lesions and hair loss in a “Christmas tree” pattern over the rump and tail base. Flea dermatitis papules tend to be found all over the body bitten by fleas.

Flea-allergic cats, on the other hand, suffer from miliary dermatitis developing ‘blackheads’ and hair loss along their back line. This is the so-called flea allergy ‘racing stripe’, although this can also occur with other skin diseases. Many owners don’t know that most itchy cats do not scratch but instead groom, so while they think the cat is frequently washing itself they don’t realize that it is actually very itchy.

Cats are such fastidious groomers that it is frequently impossible to find any evidence of fleas or flea dirt on the coat, especially if only one or two fleas are causing the problem. Intradermal allergy tests or specialized blood tests can confirm flea allergy in your cat.
