What are dog fleas?

Fleas are insects that measure approximately two millimeters, are generally reddish black in color and are characterized by jumping a lot because they have long legs adapted for that function. They are parasites with a small head, short antennae and that feed on the blood of various animals, including us. It is important that we know information about them since there is knowledge of at least 1,900 different species of fleas that can transmit diseases such as typhus, the black plague, among others.

Another important aspect to consider is that these insects have a life cycle that varies between two weeks and eight months depending on conditions such as temperature, humidity, food and species. During this cycle, fleas usually go through a complete metamorphosis in mainly three stages:

  • First, the adult fleas jump on the host, that is, our pet, and after a few minutes they begin to feed on its blood. Flea bites cause itching and irritation and can also transmit serious diseases such as those mentioned above.
  • Then, in less than 48 hours, the fleas begin to lay an impressive number of eggs that will remain on our furry and also in the environment. Did you know that the female flea lays between 15 and 20 eggs per day, up to 600 in her entire life? Scary!
  • Finally, in a few days the eggs hatch and flea larvae emerge that flee from the light and immediately hide in the carpets and cracks in the floor. The larvae spin cocoons inside which they evolve into pupae that, when the right conditions are met, emerge as adult fleas ready to jump on another warm-blooded host and perpetuate the cycle.

Waggy's recommends always being alert and preventing every illness you can and this is no exception. A single flea bites its host about 10 times a day and ingests up to 15 times its weight in blood, so in the event of a massive infestation, fleas can cause anemia and even the death of our pet.


Some of the reasons why your pet contracts fleas may be the following:

Transmission of fleas from other animals

Dogs can acquire fleas by interacting with other infested animals, such as cats, stray dogs, or wild animals.

Infested environments

Fleas can live in the environment, such as carpets, furniture, pet beds, and outdoor areas. A dog can pick up fleas from its environment if it is infested.

Lack of prevention

Lack of preventative measures, such as the use of flea products, can increase a dog's susceptibility to flea infestations.

Other animals in the home

If you have other animals at home, such as cats or even rabbits, that are infested with fleas, there is a risk of the fleas spreading to your dog.

Symptoms of Flea Bites in Dogs

As with other conditions, the symptoms and consequences of flea bites will be different in each case due to many factors such as your pet's age, breed or clinical history, to name a few. However, these are the most common symptoms that your pet could present in this case:

Intense itching

Itching is one of the most common and annoying symptoms. Affected dogs may constantly scratch, lick, or bite the affected areas.

Skin irritation

Flea bites can cause redness, inflammation, and rashes on your dog's skin.

Hair loss in the affected area

Constant itching and excessive scratching can lead to hair loss in the affected areas.

Scabs and wounds

Continuous scratching can cause scabs, sores and wounds to form on the skin.

Flea allergy dermatitis

Some dogs are allergic to flea saliva and may develop a severe allergic reaction known as flea allergy dermatitis. Symptoms may include extreme itching, redness, swelling, hair loss, and wounds.

Changes in behavior

Dogs affected by flea bites may show changes in behavior, such as irritability, restlessness, and agitation due to itching and discomfort.

Anemia (in severe cases)

In severe flea infestations, especially in small puppies or weakened dogs, the fleas can consume enough blood to cause anemia, which can lead to weakness, lethargy, and pale gums.

Secondary infections

Excessive scratching can open the skin and allow bacteria to enter, which can result in secondary skin infections.

Compulsive behavior

Some dogs may develop compulsive behaviors, such as constant licking and biting, in response to flea bites.

Weight loss (in severe cases)

In cases of severe infestations or in very small dogs, constant blood loss due to flea bites can lead to noticeable weight loss.

Diagnosis of Flea Bites

Inspecting our pet from time to time to make sure it does not have any of these parasites will always be good. With a massive infestation, fleas can already be seen with the naked eye. In addition, symptoms such as bites and redness in areas preferred by fleas may be suspicious.

Waggy's recommends always going to a professional, they will be able to diagnose your pet's flea bites through a combination of observing clinical symptoms and, in some cases, additional tests to confirm the presence of fleas or to evaluate other flea problems. health related. The veterinarian will probably take into account your pet's medical history, perform a physical examination or require some additional laboratory tests to provide an adequate diagnosis of the situation.

Treatment for flea bites will vary depending on the severity of the infestation and symptoms, but in any case we will describe some of the treatment options available, both medical and home or local:

Oral medications

These are tablets or tablets that the dog must ingest. Oral flea medications, such as lufenuron, nitenpyram, and afoxolaner, are effective in killing adult fleas quickly. There are also medications that prevent fleas from reproducing by interfering with their life cycle.

Topical applications

Topical treatments are liquids that are applied directly to the dog's skin, usually on the back of the neck. These products, such as flea pipettes and collars, provide continuous protection against fleas.

Flea shampoos

Shampoos specifically formulated to kill fleas can help remove adult fleas from the dog's coat during bathing. However, these products generally have a temporary effect and do not provide long-term protection.

Flea sprays

Flea sprays can be applied to the dog's coat and may be helpful in temporarily eliminating adult fleas and relieving itching. Again, its effect is usually short-lived.

Oatmeal baths

Baths with oatmeal products can help relieve itching and skin irritation.

Using hot creams or lotions

In cases of severe dermatitis, your veterinarian may recommend topical creams or lotions with soothing and anti-inflammatory properties.
