Allergy to Flea Bites in Dogs: Symptoms, Treatment and Prevention


The dog is an ideal host for fleas which, through their bites, can infect it. Flea saliva is allergenic and is the cause of allergic dermatitis in susceptible animals. This is also the skin disease most frequently encountered in canines. The dog then presents more or less important symptoms. It is important to consult the veterinarian so that treatment is prescribed. To avoid problems, it is essential to protect your dog against allergy to flea bites by adopting the various prevention solutions recommended by veterinarians.

Flea bites: symptoms of an allergy in dogs

This allergy can affect a dog regardless of breed, age and gender. It is a real plague for canines because of the discomfort it causes and its consequences in the absence of treatment. Not all dogs are created equal when it comes to flea bites. Some people react little to the saliva of this parasite while others develop what is called DAPP, that is to say the Allergic Dermatitis to Flea Bites whose symptoms are:

  • Severe itching
  • Important nibbling and scratching,
  • Restlessness in the dog,
  • Hotspots, red areas sensitive to inflammation,
  • Wounds that the animal inflicts on itself by constantly scratching itself,
  • Yellow patches,
  • Ulcerations,
  • Thickening of the skin,
  • Staining on the skin,
  • Suppuration,
  • Crusts,
  • Flaking,
  • Alopecia (hair loss) on the affected areas.

In general, it is especially at the level of the thighs, the abdomen, on the dorso-lumbar area, at the base of the tail and on the sides that the fleas settle preferably. By inspecting the animal’s undercoat, you can see fleas or small black dots. These are the flea feces which leave an orange or brownish-red color when rubbed with damp paper towels because they contain digested blood taken by the parasites from their host.

At the sensitive dogs, a single flea “bite” (bite) may be enough to trigger a allergy. The dog allergic to flea bites is very upset by the itching and his daily life is particularly uncomfortable. A consultation is necessary to protect the health of his pet because a severe infestation can lead to anemia.

Allergy to Flea Bites in Dogs: Treatment

The treatment of a DAPP in dogs goes through the use of a product based on cortisone against itching and inflammation, either by mouth or by injection.

A pest control in spray, pipette or in the form of shampoo must also be applied to the dog’s fur in the areas affected by the undesirable ones which must absolutely be killed. A flea collar can complete this panoply of measures which, let us specify it, do not allow to treat Allergic Dermatitis to Flea Bites, unlike cortisone.

It is important to avoid the proliferation of fleas, because by dint of recurrence, the allergic dog can suffer from the toxicity of a treatment with corticosteroids.

Prevent allergy to flea bites in dogs

It is fundamental to treat all your pets against fleas to avoid a parasite infestation which could be the cause of an allergy in one of them. At the same time, all the premises frequented by dogs, cats and other animals must be cleaned frequently: kennel, kennel, basket and any sleeping place. Let’s not forget that the house (or the apartment) is no exception to the rule. We therefore sanitize the rugs and carpets, the bedding if the dog is allowed to sit there, the sofas and armchairs, the parquet …

The flea larvae become embedded in every nook and cranny where they can stay for months before settling on their host to feed on its blood. It exists flea products and insecticides effective drugs that can be obtained from the veterinarian. The eradication of parasites must therefore be total, whether on the dog or in his environment. Finally, after each return trip, the master must take care ofinspect your dog’s coat in order to check for the presence of fleas and eliminate these allergenic parasites as quickly as possible.
