Parasites come in many sizes. Some you can see with the naked eye, but microscopes are needed for others.

These animals eat the substances produced by living beings, whether they are inside them or externally. Many of them can cause great harm to a dog.

The most common organisms that are classified as parasites are ticks, lice and fleas. These three often make the dogs itch extremely much.

Fleas and lice eat the animals’ blood. But the dangers do not end there, because they can also bring with them diseases.

Although ticks can be seen with the naked eye and their head must be removed with tweezers, the same does not apply to lice and fleas. The latter are quite small and it is not easy to find them as they hide in the dog’s fur.

For this reason, they are one of the leading causes of itching in dogs. It is therefore best to keep them away from your furry animals by keeping track of fur and skin.

Your veterinarian will recommend a good product for your dog, and there are many options on the market.

Scientific reasons why dogs itch themselves – allergies

Allergies are an immune process and manifest themselves through a series of symptoms in the presence of a foreign antigen. Under normal conditions, this foreign substance should not alter the body’s functions.

Sometimes, however, the body’s response to a foreign substance will be a strong inflammatory reaction. In fact, many existing allergies are reactions to either flea bites or atopic dermatitis.

Even scabies on the abdomen, buttocks and the inner and back parts of the thighs can make it itchy. To be able to relieve the dog’s itching, the veterinarian can prescribe anti-inflammatory medication and antibiotics.

There are some flea treatments that contain toxic chemicals that are applied by spreading them on the animal’s skin. However, these can be very toxic to the animal.

To prevent poisoning, make sure that the dog does not lick the fur. Another way to deal with this problem is to use an oral flea treatment; there are many in the market.

There are also many other allergens that can lead to itching in the dog; they can come from the environment or the food.

The measures you can take vary depending on the type of allergy involved. If you are dealing with flea allergies, you must deworm the animal.

When it comes to atopic dermatitis, you must first identify the allergen and try to remove it from the animal.

Diseases that lead to dogs scratching

Scabies is an extremely contagious condition caused by various ectoparasites and mites. It is also one of the most common conditions in dogs.

These mites transmit diseases, usually through direct contact. The type of disease depends on the type of ectoparasites the dog has.

There are times when a dog can itch for no apparent reason and this can be the result of an immune disease.

If you think this is the case then you need to confirm this by consulting a veterinarian. Only he will be able to tell you what kind of situation you are dealing with and how to deal with it.

The occurrence of parasites also varies during the year, which you should keep in mind. The same goes for allergens.

No matter what type of situation it is, you need to talk to a veterinarian to find out why your dog is itching so much. Working preventively and deworming the dog are the best cures.
