Names and pictures of internal and external parasites in dogs. You need to be wary of these dog health killers.

Internal parasites in dogs
1. Roundworms: Beige, like a rubber band, they live in the intestines and absorb digested nutrients. You can know whether there are roundworms in your stomach by checking your stool for eggs. Many female dogs are not dewormed and clean before pregnancy, so they are transmitted to puppies during pregnancy, causing the puppies to have worms in their intestines after they are born. The worm body will be corroded by gastric acid when eaten, but the round worm eggs have a thick egg shell and will not be destroyed. When the puppy is sucking milk, he accidentally licks the female dog's feces containing worm eggs, and the worm eggs escape the stomach acid. , hatch into adult worms in the intestines. Most stray dogs outside and puppies from breeding places with poor hygiene have roundworms in their stomachs.
2. Tapeworm: The tapeworm body is like a flat noodle with segments, which grow into strings. They parasitize in the intestines and absorb nutrients. After each piece falls off, it will grow its head forward, bite the dog's intestinal wall, and slowly grow a long string backward. If you see maggot-like moving worms in your puppy's feces, they are strip worms. The fragments gather near the puppy's anus, causing the puppy's anus to itch so much that it sits on the ground and grinds, as if it were sliding down a slide. And because the tapeworms violently suck out the nutrients in the intestines, the puppy becomes hungry very quickly. He eats very ravenously and eats a lot, but he remains skinny. It is not easy to see eggs in fecal examination, so diagnosis requires careful observation by the owner. This type of worm is transmitted through fleas, so puppies with fleas are almost inevitably infected with tapeworms.
3. Fishing insects: parasitic in the duodenum, also known as "duodenal worms". The insects are small and have thin hooks on their heads. They bite the intestinal wall and suck blood, causing bloody stools, black stools and anemia. Stool examination revealed an ovoid shape.
4. Whipworms: tiny whipworms that parasitize in the cecum and large intestine, causing diarrhea. Fecal examination shows oval-shaped eggs with small caps on both ends. This type of worm is now rare.
5. Coccidia: eggs as large as white blood cells, parasitic on the small intestinal tunica and in the cells, causing diarrhea. If your puppy is infected with this parasite, you must pay attention, because in canine distemper, It is also easy to be co-infected with coccidia. It is invisible to the naked eye, and there are two generations of coccidia: the sexual generation and the asexual generation alternate and mostly hide in epithelial cells, which is very troublesome to get rid of. However, there is no need to worry about infection after the dog reaches adulthood, because the adult dog's body will produce considerable of antibodies to eliminate.
6. Heart filariasis: Adult worms are like fine rice flour, parasitic in the right ventricle and adjacent large blood vessels, and are transmitted by mosquitoes. When a dog is bitten by an ant infected with larvae, the body grows and thrives as the blood flows, eventually returning to the right ventricle. After seven months, they grow into adults and begin to produce small larvae, which spread throughout the body through the bloodstream, often residing in the liver and kidneys, which are filled with small blood vessels, causing serious disorders. Adult worms increasingly gather in the right ventricle, up to 300 of them, which not only enlarges the right ventricle, but also preventsComplete return of liver blood to the right ventricle results in liver enlargement and subsequent development of large amounts of ascites. Too many worms can also travel to the lungs, causing blockages.
Dogs are prone to fatigue, weight loss, coughing, and wheezing when exercising. The nymphal body is hidden in the coronary arteries and provides nutrients to the heart. It's easy for a dog's heart to be unable to withstand the shock and die. Currently, the infection rate of wild stray dogs is over 30%. This means that one in every three dogs has heartworms. Fortunately, the current testing technology is advanced, and the test results can be known in two minutes with a small amount of blood. There are special medicines for treatment and preventive medicines for prevention, which are convenient to take once a month. In order to remove intestinal parasites, most of which must be started before injecting the puppy. Currently, there are comprehensive insecticides that can deal with all internal parasites at once and are very convenient. Insects should be cleaned as much as possible to avoid affecting the effectiveness of the vaccine. However, puppies usually fight off insects when they are young, and they will also need to fight off insects every six months to a year to avoid insects from leaking out of the net.
Dog external parasites
1. Fleas: This is the most common external parasite. It crawls quickly between the fur and is as big as an ant. After leaving the dog's skin, it jumps very quickly. Far away, hard to catch. It bites the skin to suck blood, and at the same time excretes black particles, which are like dust and are often mistaken for flea eggs. When you open the hair, sometimes you can't find fleas, only piles of "black sand". These "black sand" dissolve and turn red when exposed to water. You can easily distinguish that this is flea defecation and not dust. In addition to fleas, dogs can also be infested with cat fleas. Cat fleas are relatively small and can also bite people. They bite on people's calves. The bites are small, red and itchy, and will not disappear for several days. Unlike a mosquito bite, the formic acid secreted will swell the skin into a small red envelope. Fleas lay eggs under the skin of animals and also on fabrics. Eggs are laid on the carpet. Fleas outside the animal's body will starve to death without blood sucking, but the eggs can survive the winter if they are protected by egg shells. They hatch out in spring when the flowers bloom, and return to the dog to parasitize them. Therefore, if there are dogs at home, it is best not to use carpets. Carpets collect dirt and are also a breeding ground for fleas. In addition, outdoor grass is also a breeding ground for fleas to lay eggs, because dogs and cats will move on the grass. If you come into contact with stray dogs and cats from outside, or in garbage dumps where many dogs and cats gather, fleas will jump up when people take out the garbage and attach themselves to their pants. As the shoes and socks go home, the height of the dog is also below the knee, so jumping on them or a wild cat playing with the dog through the screen window will make it infected with fleas.
2. Tick: A fat spider that looks like eight legs. Male and female often bite the skin in pairs, but only the female can suck blood, just like a female mosquito sucking blood, making it bulging. It's as big as a mung bean. Then, just like fleas, they suck blood and excrete black particles at the same time, and the blood dissolves when exposed to water. It is called a tick because as soon as it leaves the dog, it will climb up the wall and hide in the gaps in the wall to rest or ovulate. If the unlucky dog touches it, it will be parasitized! Green spaces in parks and safety islands are oftenIts hotbed. Ticks can transmit many blood-living protozoa, such as Lyme disease, which has occurred abroad and is a zoonotic disease. There are also Ehrlichia and pyroplasia. The protozoa of Ehrlichia destroy white blood cells. Sometimes there are so many ticks that they live in the ear canal.
