Fleas are small dark brown parasites that inhabit between the dog’s fur and other animals. They are so small and fast that it is difficult to detect them, but it is easy to detect their excrement.

They develop in hot and humid climates , so they may represent a seasonal or permanent problem, depending on the climate in which they live. Fleas suck the dog’s blood and by doing so can transmit contagious diseases. In addition, dogs that have a massive infestation of fleas may become anemic.

Flea saliva can also cause allergies in some dogs, causing the dog to overeat and may even injure itself. Although it is not very frequent that fleas transmit contagious diseases to dogs, this can happen with tapeworms, worms and even bubonic plague.

Ticks are large, easy-to-see parasites . They can be felt with relative ease when caressing the dog and they are really dangerous parasites.

They cling to the skin of dogs and other mammals during their adult stage sucking their blood before they reproduce and transmit very serious diseases . They can also cause anemia when the dog is massively infested or cause a paralyzing shock.

If you detect the presence of ticks in your dog you should never pull them, you should use specific material to remove them and go to the vet right away. You can also use home remedies to prevent it from appearing .


Sarcoptic mange mites

Sarcoptic mange mites are microscopic parasites that settle on the dog’s skin. Cause, as you would expect, mange. These parasites can spread to other animals, including humans.

These mites cause skin irritation, hair loss and scabs. If the disease is not treated, it can cause other organic disorders and the dog may die.

Mites of the demodic sarna

Demodectic mange mites are long and microscopic. They are part of the microfauna of the dog’s skin and are not highly contagious. The disease occurs when the concentration of these mites increases, although the causes of this are not known. These mites cause the so-called demodectic mange, which can occur in two varieties: localized and widespread.

Localized demodectic mange is a mild problem that usually resolves spontaneously in most cases. Its symptoms include localized loss of hair, scaling and dark spots.

Generalized demodectic mange is a serious condition that can lead to the death of the dog. It presents initially with localized loss of hair, but with time there are collateral complications. The most common complication is bacterial skin infection or pyoderma, which includes pruritus, inflammation of the lymph nodes, suppuration and stench.

Mites of the ears

The ear mites are identical to the sarcoptic mange mites, but are slightly larger. They are contagious by direct contact of the dog with other infected animals or with surfaces where these parasites are found.

These mites establish themselves in the auditory canal and adjacent areas, and cause an annoying irritation and itching in the dog .

To relieve the discomfort, the dog itches constantly and can get to do it too much. You can rub your head often against walls and other rough surfaces, and you may even get hurt from scratching yourself.

The dog infected with these mites shakes their head very often . It is also common to see dark fluid coming out of the ear canal. If the infection is very severe, the dog walks in circles.

Treatment of external parasites

Like any medical treatment of the dog, treatment of external parasites should be carried out and / or recommended by the veterinarian . Still, when there are many commercially available anti-parasitic agents, it is recommended that the veterinarian decide what treatment to follow in each case.

Do not forget the importance of preventing the appearance of all these problems with the use of pips or collars anti parasites. Bathing the dog and cleaning your ears are also good ways to prevent it .
