Parasites review

Parasite is an organism, that lives in or on other organism and feeds for its cost. Some of these tiny beasts travel from one animal to another and even to people ( we should always remember that we are under a definite risk as well as we contact with our pets by touches, air and the same living space).

Remember, that the majority of pests attack our pets regularly, especially in warm weather conditions. It would be silly to consider that dogs may get pests only out of the city. City loans, streets are a huge field for different insects and worms, a great source of pests that are concentrated in dog and cat feces.

Hookworms take approximately 90% of all inner pests types. Nematodes are the most common pests of dogs and cats. They transfer from lungs to bronchia and then migrate to intestines where they may live for a long time, even forever. They pest at many organs: intestines, liver, lungs, heart and muscles. The most common are toxocara and toxocaria, that provoke diseases with the same name toxocariasis and toxocaridosis. A serious infection will show the following sighs: paunchy belly, dull fur, bad weight. It may seriously weaken or even kill a young puppy. Sometimes it is possible to see the worms in dog feces and vomiting. They are from 6 to 20 cm long and they struggle for consuming of dog's food, taking its nutrition and important elements for dog's health and activity. As the result, a dog is hungry, though it eats a lot of food.

Hookworms infect people also. They can easy get into human organism in bad sanitarian conditions, after contact with feces, especially if a person cleans hands not good enough after cleaning of feces. The greatest danger they are for kids under 3 years old, who tend to take everything to their mouth to taste all the objects around.

Majority of pets are born with worms (toxocara canis). Though majority of adult feminine dogs have no active worms, they may transfer "sleepy" pests to their offspring while being in the womb. Puppies product tiny worm eggs with the feces and a mother-dog eats it, and the circle repeats. many dog breeders get rid of puppy's worms in the first 2-4 weeks after birth and repeat the cure more 3 times with interval of 2 weeks each. The veterinary will give you a safe remedy for the puppy worms depending on its type found in the feces.

Though toxocara and toxocariases are alike by look, toxocartiases are much more dangerous. Eggs of both these worms are excreted to the outer space with dog feces. Then only after a fortnight they can infect the new animal to live in. The eggs ripen in the circumstances of enough wet and warmth. The peak of of infection is the period from spring to autumn.

A dog swallows ripe warm eggs with ground. Rodents and small animals may gather warm eggs and serve just as their sources. This way the cycle of warms in the nature.

And then there appear warm larvae in a dog intestines. Toxocariases involve themselves into the intestines epithelium and ripen there. In the process of growing they cause damage to the intestines epithelium and cause dog diarrhea with blood. These worm type is usually found with dogs above 6 month. The disease usually flows invisibly and or shows by bad or strange appetite, constipation, that changes with diarrhea. That's why it is so important to take the analysis for warm eggs after dog eats from the ground, grass, strange appetite to different unusual food. Toxocaria do not involve them into the intestines epithelium but try to flow into blood vessels. At first they get into the liver and damage it. The more eggs simultaneously get into the intestines the more damage will be caused. They may count more hundred. But their finish point are lungs. They flow here to proceed their cycle of developing. Larvae are ripe and proceed to get involved into capillary walls getting into bronchia. At this stage there may appear cough and pneumonia sometimes even with blood. Then the ripe worms go to the intestines again to proceed their developing cycle. A dog cannot cough all the wet out and swallows it. And this way the toxocaria go again to the intestines. There they are ready to produce new eggs. The greatest damage they cause to puppies, whose immunity is weak yet and they may cover all the intestines of a poor animal. They may break the intestines with their activity and cause death of a puppy. All worms cause great damage to all the dog organism, weaken digestive processes and nutrition. Then follow intoxication and lack of vitamins. All these factors of course will affect the look and feeling of your pet.

Prevention: twice a year analysis for worm eggs, following of hygiene rules, keeping of clean surrounding, taking worming remedies once a quarter, and once a three months for puppies.

Uncinariosis (Uncinaria stenocephala) is the number two among the pests, but the most dangerous among the dog parasites, especially for puppies. As well as hookworms they can transfer from mother dog to puppies through feces contacts or involve through not protected dog skin. They are located in the intestines sticking to its epithelium and suck blood that causes anemia and even death of a puppy. The mouth of these worms has special gland that produces a substance, that causes lack of erythrocytes and hemoglobin in puppy blood. Symptoms: bloody diarrhea, dull and dry fur, loss of weight, weakness, enormous appetite, abdominal distention. Adult dogs may show no symptoms.

Tape worms look like moving rice seeds. Many handlers get to know about dog infection with tape worms by their appear in dog feces. Tape worms may also infect carpets, furniture, dog underlay.

The most widely spread is a dipilidium or a cucumber tapeworm. Its head with suckers is so small, that it may be distinguished only under a microscope. It can grow to 2 m long. Ripe segments have size of a cucumber seed, white-yellow color. They are well seen at dog feces. They have self-activity and proceed to move for some time. Though segments are full of eggs, they are not dangerous themselves for a dog and a human.

Dipilidium has a complicated life cycle. In the order to proceed it, its eggs should be eaten by a fleas. These pest is a common parasite of uncared dogs. Worm eggs are eaten by flea larvae. They alvays live not on the animal but beside, at the living space of a dog, on the carpet, underlay and is fed by organic leavings.

It may kill a dog if not admitted and without cure. A dog gets infected by an infected mosquito and the eggs go into the blood flow. Larvae go into muscles where they ripen for 3-4 month growing into small worms.

Then they flow into veins moving forward to the heart and base at the right part of it, ready for reproduction. A female may produce about 5000 eggs a day. This colony will stay and wait until another mosquito will bite a dog and they will proceed the life cycle spreading in another dog.

Adult worms get 10-30 cm of length and spread in heart and lungs. The result is as follows: low blood flow and heart stop.

The symptoms of this disease may not show for a year after infection. The most frequent sigh is a soft deep cough that becomes gradually stronger. A dog becomes apathetic, easy gets tired, loses weight. Fur becomes dull and dry. A dog may cough with bloody wet.
