it is not hygienic and, therefore, not permissible to keep a dog in the house
If the saliva of a dog touches you or any part of your clothing, then it is required [that] you ? wash the body part ? and the item of
clothing [that was] touched by the dog’s mouth or snout.

All animals are part of god’s creation, and each animal has been created for a purpose. It is a duty upon every human being to respect god’s creation? It, thus, becomes our duty to protect, employ with dignity, and promote the well-being of any animal in our care. In this way, we are expressing our thankfulness to god for His blessings in a practical manner.

caution toward dogs is fundamentally a matter of hygiene and protection from parasite infection transfers to humans.

See Dr. Hulda Clarks book called the Cure for All Diseases in PDF form here.

The most common diseases associated with dogs that can cause human illness are:
  • Campylobacteriosis (Campylobacter spp.) ...
  • Dog Tapeworm (Dipylidium caninum) ...
  • Hookworm (Zoonotic) (Ancylostoma caninum, Ancylostoma braziliense, Uncinaria stenocephala) ...
  • Rabies. ...
  • Roundworm (Toxocara spp.) ...
  • Brucellosis (Brucella spp.)

    Vector-borne diseases are those transmitted by fleas or ticks among other parasites that infest dogs and cats. They can affect pets and people. Ticks can transmit a large number of “vector-borne” diseases in North America including ehrlichiosisLyme disease, relapsing feverRocky Mountain spotted fever and tularemia.

    Parasites can be spread from pets to humans
    Zoonotic diseases, or zoonosis, are infectious diseases that can be transmitted directly and indirectly to people from animals.

    Some intestinal worms commonly found in dogs and cats can be a health risk to pet owners. Hookworms and roundworms are two of the most common parasites found in our pets that have zoonotic potential for humans.

    These worms can be very prolific and one worm can produce more than 100,000 eggs a day. Once the eggs are passed in your pet's feces, and spread throughout their environment, they can remain infective for years. Here are answers to some of the most frequently asked questions about these two parasites.

    What are Hookworms?

    Hookworms live in the small intestine and are blood suckers that can cause severe anemia or blood loss in pets. Puppies are very susceptible and can die from anemia. Dogs and cats can become infected with hookworms by ingestion of the larvae from the environment or from nursing an infected animal.

    Animal hookworms are well-documented zoonotic disease agents and are the most common cause of cutaneous larva migrans (CLM) in people. Cutaneous larva migrans also is known as creeping eruption or ground itch. The larvae migrate in the skin, producing intensely itchy, serpentine lesions. Humans are most likely to be infected with the hookworms of dogs and cats through direct skin penetration of infective larvae found in feces of dogs and cats.

    What are Roundworms?

    Roundworms are the most common intestinal parasite in pets and the most likely to be transmitted to humans. They live in the small intestine and puppies are especially vulnerable. Pets become infected through ingestion of infective larva from the environment, through the placenta before birth and from nursing.

    Humans become infected with roundworms by accidentally ingesting infective worm eggs that have been passed through the pet's feces and left in the environment. The eggs then can hatch in the human's intestinal tract, and the immature worms can travel to various tissues in the body, including the eyes, brain, liver, lungs, and other organs potentially causing serious infections. These infections are known as ocular larva migrans and visceral larva migrans.

    Who is most at risk? those who keep dogs in their homes and in human beds

    How do you prevent infection? Keep them outside and wash hands thoroughly after contact. Their coats are filled with parasite eggs that rub off onto your hands and then you touch your face, eyes, hair and you have just transferred the parasite to yourself and your family who then touches you. 

    Practicing good hygiene is the key to preventing infection. Protective steps include promptly removing animal feces from your yard, covering children's sandboxes when not in use, wearing shoes and gloves while gardening and washing hands thoroughly after playing outside or working in the soil. Also, using a monthly preventative and annual fecal testing are important in prevention of disease. Monitor children playing outside in sandboxes and parks and abiding to leash laws also aid in prevention. If you suspect you or a member of your family have been infected, it is very important to consult your physician for diagnosis and treatment.

    The MOST COMMON Parasites in Dogs, article here.




    Roundworms are the most common type of parasitic worm found inside our pets: up to 30% of dogs and 70% of puppies are infested with Toxocara canis.1,2

    Roundworms are highly prolific and females can lay up to 300 000 eggs per day. Infested dogs shed these microscopic eggs via their droppings into the environment, where they become infective after 2 to 3 weeks. The eggs can stay alive and remain infective for up to 5 years, as they are resistant to hot and cold temperatures, as well as disinfectants. Other dogs become infested as they swallow these eggs when they sniff or lick soil or other substances soiled by faeces. Dogs may also get infested if they eat rodents or other small mammals that can carry roundworm larvae.

    Puppies can be infested with roundworms from birth as the mother can pass worms to her puppies during pregnancy, and via her milk when nursing.


    Adult roundworms live in the dog's intestines and many dogs do not show any sign of illness. However, dogs that have a major infestation, particularly puppies, can show digestive signs such as a potbelly, diarrhoea and vomiting. They may also have respiratory signs as the immature worms pass through their lungs, leading to coughing and pneumonia.


    • Humans can be infested with pet roundworms too. In infested people, the worms can cause a variety of health problems, one of the worst being blindness.
    • Children are particularly at risk as they often play on the ground or in soil where worm eggs may be present (in parks, sandpits etc.). Adults may be exposed during activities such as gardening. In one study 66% of soil samples from parks in a major city were positive for Toxocaraeggs3

#1 – Giardia

Giardia is a Protozoal parasites often from contaminated drinking water. Infected dogs can serve as a source for humans, as can infected humans serve as a source for their dogs. Although very difficult to be sure that your dog never drinks from puddles that could contain the fecal matter of infected wildlife, you can treat and filter water when you are hiking and camping to protect yourself and try to encourage your dog to choose treated water when thirsty.

Symptoms in pets: Diarrhea

Symptoms in humans: Diarrhea


#2 – Roundworm

Roundworm is technically zoonotic and can cause horrific skin and ocular lesions in affected humans. The incidence is thought to be higher in children more likely to come in contact with the feces of pets. There are other intestinal parasites that can cause human disease as well. Careful handling of dog feces is imperative and always washing your hands after handling feces or the dog prior to eating especially.

Symptoms in pets: Diarrhea, visible worms in stool, vomiting, constipation, coughing, bloody stool

Symptoms in humans: Cough, shortness of breath, abdominal pain, blood in stool


#3 – MRSA

Methicillin resistant Staph Aureus is more of a problem from humans to pets. I have treated these infections many times, mostly in ears and wounds. If your pet has non-healing wounds or chronic recurrent ear infections, a culture at your vet would be a really good idea.

Symptoms in pets: Fever, discharge from a wound, skin lesions, skin swelling, slow to heal wounds

Symptoms in humans: Generally start as small red bumps that resemble pimples, boils or spider bites. These can quickly turn into deep, painful abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin.


#4 – Sarcoptic Mange

Often called Scabies, Mange is caused by a tiny mite that burrows deeply into the skin creating severe itching and irritation. Secondary infections are common for infected dogs and it is not only contagious between dogs, but also can infest humans. Humans are a “dead end” host which means the infestation will be self-limiting and infected humans do not lose all of their hair like infected dogs can. But the mites cause profound itching. If your dog is extremely itchy and is missing patches of hair, call your vet right away,especially if your dog has been around other dogs that you don’t own or has been boarded or grooming with other dogs.

Symptoms in pets: The symptoms of mange depend on which type of mite is present. Demodectic mange tends to cause hair loss, bald spots, scabbing and sores. Secondary bacterial infections can make demodectic mange an itchy and uncomfortable disease.  Sarcoptic mange tends to cause intense itching. It can result in restlessness and frantic scratching, symptoms that generally appear one week after exposure. It also can result in hair loss, reddened skin, body sores and scabs. The most commonly affected areas are a dog’s ears, elbows, face and legs, but it can rapidly spread to the entire body.

Symptoms in humans: sarcoptic mange causes a rash of red bumps, similar to mosquito bites. Humans cannot get demodectic mange from dogs.


#5 – Salmonella

Salmonella is a bacteria that can be found in contaminated and undercooked food.  It can make people and dogs very sick with GI signs and I discourage feeding of raw meats in part for this reason. Poultry for example should be cooked to a minimum temperature of 165 degrees to make it safe to eat for pets and people.

Symptoms in pets: Reptile pets and chicks often don’t show symptoms

Symptoms in humans: Abdominal pain, fever, vomiting, headache, nausea



#6 – Ringworm

Dermatophytosis or ringworm is a fungal infection of the skin. I see it in dogs and cats, although cats are more likely to be assymptomatic carriers. I think that animals are often blamed for infections in children, but ringworm can be found in soil where children play.

Symptoms in pets: Skin lesions and patches of hair loss with a red mark in the center

Symptoms in people: Red, circular patches on the skin



#7 – Leptospirosis

Leptospirosis is a bacterial infection that is spread through contact with the urine of an infected animal. Potential sources can be wildlife, like mice and rats. Contaminated standing water is thought to be a source. Infected dogs can be a source for their humans handling their urine so if your dog is sick with fever, lethargy +/- jaundice, please contact your vet immediately.

Symptoms in pets: fever, muscle pain, vomiting and diarrhea, loss of appetite, lethargy, depression, and blood in the urine. More serious infections can cause jaundice and blood clotting problems.

Symptoms in people: High fever, headachem chills, miscle aches, vomiting, jaundice (yellow skin/eyes), red eyes, abdominal pain



#8 – Rabies

Rabies is a virus that can infect mammals. It is spread in the saliva or contact with infected tissues. Suspected rabies or even any human bitten by an unvaccinated (or past due) dog must be reported to the health department. Bats serve as a source in the wild, as do raccoons and other wildlife. There are very few human cases that have survived once the symptoms have evidenced themselves.

Symptoms in pets: Fever, seizures, dropped jaw, inability to swallow, change in bark tone, muscular lack of coordination, excessive salivation or frothy saliva

Symptoms in humans: Temperature of 100.4ºF, chills, fatigue, problems sleeping, lack of appetite, headache, irritability, anxiety, sore throat, vomiting.  Around half of people will also experience pain and a tingling sensation at the site of the infection.



#9 – Hookworms

Hookworms suck on the intestinal lining of dogs, causing a potentially life-threatening blood loss, especially in puppies. The eggs found in pet feces could transfer through the skin in pet owners if you happened to, say, step on a dropping with your bare feet in the backyard.

Symptoms in pets: Diarrhea, weight loss

Symptoms in humans: Often none but could include an itchy rash, cough, wheezing, stomach pain, anemia, or loss of appetite


#10 – Tapeworms

Tapeworms are flat segmented worms that live in the intestines of some animals. Animals can become infected with these parasites when grazing in pastures or drinking contaminated water.

Symptoms in pets: Dragging back end across the ground; rice-like pieces in the pet’s stool or longer worms in pet vomit

Symptoms in humans: nausea, weakness, diarrhea, abdominal pain, hunger or loss of appetite, fatigue, weight loss. rice-like pieces in stool
