Is there any harm to the human body of having a dog?

Pets are believed to be good companions, but researchers have pointed out that there are more benefits to owning a dog than a cat. Dr. Weiss, a psychologist at Queen's University Belfast in the United Kingdom, found that dog owners generally have lower blood pressure and cholesterol. Published in the British Journal of Health Psychology, Dr. Weiss explains that walking dogs regularly may be what makes dog owners healthier.

After reading a large number of research reports on the benefits of pet ownership, she came to the conclusion that pet owners are generally healthier than others. But her research also found that dog owners benefit more than cat owners. In addition to lower blood pressure and cholesterol, dog owners are less likely to get sick, she said.

The report also mentions that dogs help owners recover from serious illnesses such as heart disease and can give "advance warning" of seizures of epilepsy. Dr. Weiss is not able to provide a definitive explanation for this phenomenon, but she deduces that stress is the main cause of illness and that dogs may be able to relieve people's stress. In addition, owning a dog can also increase people's activity and promote relationships, which can indirectly affect people's physical and mental health in good ways.

Dr. McNicholas, a health psychologist who specializes in the effects of pets on human health, points out that not only do dog owners have the opportunity to move their dogs when they walk them, but also because walking their dogs provides opportunities for dog owners to socialize. "In some cases, animals can provide more support than people," she said.

So the pros of having a dog outweigh the cons!

In rural areas, dogs can play the role of caretaking. The disadvantage is that dogs may have body odor and are more susceptible to parasites, such as lice, fleas, ticks, etc., so they need to be dewormed regularly. In addition, the dog will feel discomfort during tooth change and may tear furniture.

First: Dogs shed a lot of hair, polluting the sanitary environment of the home, and their excrement may spread germs. Second:

Dogs love to bark, which can cause noise pollution. Third: Dogs will bring inconvenience to the owner's travel.

Fourth, dogs need a lot of energy from their owners to take care of them.

Dogs have bacteria all over them. So don't have too much physical contact. It doesn't do much good for your health.

The following diseases may occur, but they can be avoided by paying attention to personal hygiene and immunizing the dog on time.

1. Rabies.

It is a zoonotic disease caused by the rabies virus, especially an acute contact infectious disease that animals are prone to. The disease is mainly contracted by bites of rabid dogs, mad cats and diseased domestic animals, and the disease can occur in all seasons, but it is more common in spring, summer and winter. The incubation period of the disease varies from as short as about 12 days to as long as 1 year.

2. Trichinosis.

It is a parasitic disease caused by Trichinella that humans and carnivores are susceptible to, and humans, dogs, pigs, cats, etc. are highly susceptible. The patient is infected by ingestion of pork, dog meat, etc., containing Trichinella cystis, or contact with fresh feces containing cysts. Humans are susceptible to the disease, and it can be fatal if swallowed as long as 5 live worms per kilogram of body weight.

3. Toxoplasmosis.

Cats are hosts to Toxoplasma gondii and reproduce sexually in cats, which often become ill by ingesting raw meat or prey containing trophozoites. Once a person is scratched by a cat or infected by other means, some people may experience fatigue, fever and headache. Most obvious clinical signs are only lymphadenopathy.

4. Echinococcosis.

This disease is a parasitic disease of the larvae of Echinococcus granulosus in the small intestine of dogs, and the liver, lungs and other internal organs of humans and animals. Echinococci are sac-shaped, with small bean-like and large bulbous shapes, with different shapes. Patients with this disease often present with long-term intractable digestive disorders, nutritional disorders, gas, emaciation or jaundice, and lung invasion.

Raising a dog is not only not harmful to the human body, but also helps people enhance their immunity; Studies have shown that children who have grown up with pets from a young age are twice as likely to be allergic to pets as the general population. Because children are exposed to pet dander or allergens before the age of one, they can help the immune system.
