Can Dog Diseases Be Transmitted To Humans?

Posted on

Dogs not only provide comfort and tranquility, but many studies have found that dogs reduce stress and promote relaxation. Dogs have positive impacts on almost all life stages. They affect social, emotional, and cognitive development in children, encourage an active lifestyle and have even managed to detect oncoming epileptic seizures or the existence of certain cancers. However, for all the positive advantages of maintaining puppies, pet owners should bear in mind that dogs may carry germs that make people sick.

Although germs from puppies seldom spread to people, they may cause various illnesses, which range from minor skin infections to severe illness.

Can dog diseases be transmitted to humans? The  answer is yes

The most common ailments associated with puppies that can cause human illness are:


Rabies, a fatal neurologic disease in people and animals, is caused by a virus. Infected dogs may have an assortment of signs, but most often have a sudden behavioral change and progressive paralysis.

The initial symptoms in people may begin days to months after exposure and include generalized weakness, fever, and headache. In a few days, symptoms will progress to confusion, anxiety, behavioral changes, and delirium. In case you were bitten by a dog or other animal and believe that there’s a risk for rabies, contact your medical care provider immediately. Once symptoms appear, it’s almost always too late for therapy.


Campylobacter spreads through contaminated foods (eggs and meat), water, or contact with feces of infected animals. Dogs infected with Campylobacter might reveal no symptoms of illness at all or may have diarrhea and a small fever.

Most people who become ill with campylobacteriosis will have diarrhea, cramping, abdominal pain, and fever within 2-5 days after exposure to the organism. Campylobacter can result in serious life-threatening illnesses in infants, elderly individuals, and people with weakened immune systems.


Toxocara roundworms cause a parasitic disease called toxocariasis. Dogs and people can get infected by accidentally swallowing roundworm eggs in the environment. Additionally, larval worms may cross through the placenta, milk, or colostrum of a mother dog, passing the disease to her puppies. Infected puppies normally do not grow and grow well and may have a pot-bellied look.

In people, children are generally affected with roundworm. There are two types of this disease in people. Ocular larva migrans occurs when the larvae invade the retina and lead to inflammation, scarring, and possibly blindness. Visceral larva migrans occurs when the larvae invade parts of the body, like the liver, lung, or central nervous system.

Dog Tapeworm

The dog tapeworm is a parasite spread to cats, dogs, and individuals throughout the ingestion of infected fleas. This parasite is common but rarely causes illness in people or pets. Infection with Dipylidium caninum can sometimes be detected by finding rice-like parts of the tapeworm crawling close to the anus or in new bowel movements. In acute infections, pets may get rid of weight and have moderate diarrhea.

In people, kids are more commonly infected but do not usually show signs of disease. The best way to avoid disease in pets is to control the flea population in the surroundings.


Dogs may also become infected with hookworms through inadvertently ingesting the parasite from the environment or through their mother’s milk or colostrum. Young puppies are generally affected and may have dark, bloody stool and anemia. Severe infections in certain puppies may result in death.

People become infected with dog hookworms while walking barefoot, kneeling, or sitting on ground contaminated with feces of infected animals. A red squiggly line may appear in which the larvae have migrated beneath the skin.
