Tick in a dog: types of parasites and symptoms of possible diseases
The flowering period and autumn leaf fall, in addition to external beauty, have a downside. At this time, ticks wake up – parasites that carry dangerous diseases and pose a threat not only to four-legged friends, but also to their owners. In case of defeat by a blood-sucking insect, immediate action is required. We will understand what the tick is dangerous in a dog, what symptoms may appear and what treatment is necessary.
Causes of infection (route of infection)
All existing ticks are divided into 3 groups:
Intradermal, living inside the canine organism in a sleeping form all life. They are dangerous only under certain conditions.
Subcutaneous, falling from the outside and penetrating deep into the skin.
External sucking on the outside of the body.
Representatives of intradermal ticks include iron ore (demodex), which provokes the development of demodicosis. It populates hair follicles and sebaceous glands. A danger to a pet arises in the event of:
weakened immunity (chronic diseases or immature puppies);
communication with an infected dog;
contact with infected things (toys, collar);
Species of ticks
Scabies is caused by subcutaneous mites, a disease that occurs in 2 forms, depending on the type of parasite:
Notoedres, provoking nothedrosis and affecting the outside of the auricles;
small tick Sarcoptes scabiei, threatening the development of sarcoptosis, spreading over the entire surface of the skin.
The group of external ticks is represented by the most famous and dangerous ticks – Ixodidae, causing:
Pyroplasmosis. The danger comes not only from adults, but also from larvae that parasitize in the warm season and live in thickets of grass.
Encephalitis. The lightning-fast development of the disease does not always save the pet.
The timely detection of ticks is complicated by the lack of individual symptoms. The emerging symptoms are similar to other diseases, so it is important not to make independent diagnoses, but to seek specialized help.
Please note that the severity of symptoms increases in:
pets with chronic illnesses;
young dogs under 2 years old and puppies;
thoroughbred representatives with a rich pedigree.
Moreover, in adults and healthy individuals, the disease can occur in an asymptomatic form, which leads to sad consequences.
If with a direct bite, external manifestations are usually absent, then after a while it is noted:
increase in general temperature;
refusal of food (the dog is not even attracted to favorite treats);
itchy sensations, accompanied by constant combing;
lethargy and loss of previous activity;
gastrointestinal upset (mucous vomiting, feces changes color to green or yellow);
coffee-colored urine with blood.
Consider the symptoms in more detail in the context of the species of parasites.
When the dog is affected by demodicosis:
irritated skin turns red and itches at the site of the bite due to the received toxins;
wool begins to fall out;
suppurations, age spots and tubercles appear.
Depending on the type of disease, the affected area is local in nature or spreads to other parts of the body.
When infected with a subcutaneous tick:
wool falls up to baldness;
anxiety and aggressiveness appear;
severe itching occurs, leading the animal to bloody combs and hematomas on its paws;
suppuration and dandruff are formed.
An ear mite, in addition to itching and inflammation, adds a dark gray discharge from the auricles, which has an unpleasant odor.
Red blood cell-destroying pyroplasms cause an increase in hemoglobin. As a result, the kidneys, spleen, liver and even the brain, which lacks oxygen, suffer. The defeat of ixodid ticks that carry unicellular pathogens leads to one of the forms of pyroplasmosis:
Sharp. In this form, the disease occurs in dogs that become ill for the first time. Key symptoms include:
shortness of breath
rise in temperature to 42 °;
increased heart rate;
lack of appetite;
yellowing of the mucous membranes of the eyes and oral cavity;
apathy and worsening reactions;
difficulty walking and possible paralysis of the hind legs.
Subacute. Symptoms are similar to the first form, but are less pronounced.
Chronic Such a course is characteristic of animals with a strong immune system and those who suffer the disease repeatedly. In this case, among the symptoms are:
a short increase in temperature, returning to normal after a few days;
lack of energy, depression and exhausted appearance;
loss of appetite;
bowel problems (loose stools).
