What should I do if my Mexican hairless dog has worms? There are many things to pay attention to when raising a dog. For example, what should you do if your dog has worms? At this time, the best way is to send it to a pet hospital for treatment.

First of all, we must be good at detecting abnormal conditions in dogs, that is, disease conditions! Generally, if a dog has parasites, it will generally suffer from varying degrees of mental depression! Of course, there are also some symptoms that will not be too obvious. , but if it is discovered, it is best to use a dog-specific external spray to perform a simple insecticide immediately, and then go to the pet hospital for examination.

In addition to the above, the usual prevention work mainly focuses on two major aspects.

On the one hand, we must do a good job in the hygiene of the dog itself. It is best to regularly check the hygiene of the dog's hair roots, behind the ears and mouth. If it is not hygienic enough, these three places will be more obvious. If you find it dirty, it is best to clean it in time. The simplest way is to take a bath regularly. It is recommended to wash it every day in the summer. In other seasons, it is best to wash it every two or three days! However, it should be noted that when the weather is warmer, When it's cold, it's best to use a hair dryer to dry your dog's hair after washing to avoid catching cold and getting sick.

On the other hand, you should pay attention to the hygiene of the dog activity areas. It is recommended that friends clean the kennel regularly. It is best to simply clean and disinfect some toys that are often given to dogs. Here, I would like to remind you that it is best not to use used tires for dogs to play with. Such tires are not easy to clean and can easily attract some easily transmitted parasites!

Dog ascariasis is one of the common diseases in dogs. It is caused by Ascaris canis and Ascaris leonata parasitizing the small intestine and stomach of dogs. It is widely distributed in my country and mainly harms puppies between 1 and 3 months old. , affecting longevity and development, and severe infection can lead to death.

Pathogens and their life history

The canine roundworm (Toxocara canis) is light yellow in color, has three lips at the head end, and a narrow cervical wing membrane on the side of the body. The characteristic of canine roundworm is that it has a small stomach at the junction of the esophagus and the intestine. The male worm is long 50-110 mm, with a curved tail end; the female worm is 90-180 mm long, with a straight tail end. The color and shape of the lion roundworm (Toxocara lionsis) are similar to those of the canine roundworm, but without a small stomach; the male worm is 35-70 mm long, and the female worm is 35-70 mm long. Insects are 30-100 mm long.

Canine roundworm eggs are excreted with feces and develop into infective eggs under suitable conditions. After puppies under 3 months old swallow infective eggs, larvae will hatch in the intestines, and the larvae will penetrate into the intestinal wall and pass through the intestines. The lymphatic system travels to the mesenteric lymph nodes, then reaches the liver through the blood flow, and then reaches the lungs with the blood flow. The larvae pass through the alveoli, bronchioles, and bronchi, and then are swallowed into the stomach through the larynx. They further develop into adult worms in the small intestine. The whole process takes 4-5 weeks. .

After an older dog ingests infectious eggs, the larvae travel to various tissues and organs of the body with the bloodstream and form cysts. The larvae remain active but do not survive.Further development; after the female dog containing the cyst in the body becomes pregnant, the larvae are activated and migrate through the placenta to the fetal liver to cause intrauterine infection. After the fetus is born, the larvae migrate to the lungs, and then migrate to the gastrointestinal tract to develop into adult worms. Mature canine roundworms appear 23-40 days after the birth of the puppies. Newborn puppies can become infected by sucking colostrum; after infection, the larvae develop directly into adult worms in the small intestine. Lion roundworm eggs develop into infective eggs under suitable external conditions. After being swallowed by dogs, the larvae escape in the small intestine, burrow into the intestinal wall, develop, and return to the intestinal cavity. They develop into adult worms in 3-4 weeks. .

Key points in diagnosis

(1) Clinical symptoms: Gradual weight loss and pale mucous membranes. Loss of appetite, vomiting, heterophilia, digestive disorders, first diarrhea and then constipation. Epileptic spasms are occasionally seen. Puppies have enlarged abdomens and delayed growth. When the infection is severe, roundworms are often excreted in the vomit and feces, and the diagnosis can be confirmed.

(2) Laboratory examination: The saturated salt water flotation method or the direct smear method can be used to check the eggs in the feces for diagnosis.

Preventive and control measures

(1) Regular inspection and deworming: Puppies will be inspected once a month, and adult dogs will be inspected once a quarter. If a sick dog is found, deworming will be carried out immediately. Levamisole can be taken orally at 10 mg per kilogram of body weight. Or use mebendazole, 10 mg per kilogram of body weight, taken twice a day for two consecutive days, or use pyrantel (pyrimidine) 5-10 mg per kilogram of body weight, taken orally. Or use piperazine citrate (dispelling ascarid) 100 mg per kilogram of body weight, taken orally.

(2) Do a good job in cleanliness and hygiene: The environment, troughs, and food must be cleaned carefully, and feces should be removed in a timely manner and fermented.
