Dog Diseases


Leptospirosis is a bacterial disease that can be found in dogs, rats and livestock.

It causes fever, headache, chills, muscle aches and vomiting. If left untreated it can lead to liver damage or meningitis (inflammation of the membrane that covers the brain and spinal cord).

A person with leptospirosis will need antibiotics to kill off the bacteria; if untreated leptospirosis can be fatal.


Salmonella is a type of bacteria that can live in the intestinal tract. When you eat contaminated food or drink contaminated water, salmonella is transmitted to your body through your mouth, nose and intestines. The bacteria attach themselves to the walls of your intestines and produce toxins that cause diarrhea, abdominal cramps and fever.

Salmonella poisoning is most common in children under 5 years old because they have weaker immune systems than adults. Symptoms typically occur 12 to 72 hours after infection, but sometimes can take up to 7 days for them to appear. The symptoms last between 4-7 days if untreated but usually go away on their own within 5 days without treatment (with antibiotics).

There are no vaccines against salmonella available currently but research is ongoing for one in development at University College London’s Center for Infectious Diseases and Microbiology


Rabies is a viral disease that affects the nervous system, causing inflammation and swelling of the brain. It’s fatal if not treated.

You can get rabies from your own pet dog or cat, as well as other animals like raccoons, bats, skunks and foxes. While rare in humans in the United States (only six human deaths have been reported since 1970), it’s still important to know about because there are certain circumstances where you may be at risk for infection.


Campylobacter is a bacteria that causes gastrointestinal distress and fever. It is spread through contact with infected animals, contaminated water or food, or by touching surfaces that have been contaminated by animals infected with the germs.

The symptoms usually last for about a week, but they can be serious in some people who are at high risk for complications such as older adults and people with underlying health problems. The most common complication is reactive arthritis (inflammation of joints), which may cause long-term joint pain if not properly treated immediately after infection occurs.

If you get sick from Campylobacter, you should see your doctor to determine if antibiotics are needed to treat your illness and prevent further complications from developing later on down the road!


Toxocariasis is a disease caused by a parasitic roundworm called Toxocara canis. The eggs of this parasite are shed in the feces, and humans can become infected by coming into contact with those feces either directly or indirectly. Infection is more common in children because they tend to play on the ground where dogs may have left their feces behind. An infection with this parasite can cause eye problems, asthma, and even hearing loss if it goes untreated for long enough.

The best way to prevent toxocariasis is through vigilance about keeping your pet’s waste picked up so that other kids or adults don’t come into contact with it while playing outside or taking walks around town!


MRSA is a type of staph infection that can cause skin infections. Staph is short for Staphylococcus, a type of bacteria. MRSA can spread from dog to owner and vice versa through contact with infected skin or objects like towels and sheets that have been used by an infected dog.

It’s also possible for MRSA to be spread between humans and dogs by touching an infected person’s hand, then touching the animal or vice versa.

You can catch some diseases

  • You can catch some diseases from your dog.
  • Your dog might have a disease that you can catch, such as the flu or rabies.
  • If you think you’ve caught one of these diseases from your dog, take them to the vet right away for treatment and make sure to wash your hands thoroughly after touching them or cleaning up after them. Also, keep an eye on their recovery process and don’t let them lick anyone or anything until they are completely over it!
  • There are many ways to prevent catching a disease from your pet—knowing what they are helps keep everyone in the household healthy.*

If you’ve ever wondered if you can catch a disease from your dog, the answer is yes. Most people are familiar with the most common diseases that humans get from their pets, like fleas and ticks. But there are also other serious (and sometimes fatal) illnesses that can be transmitted from dogs to humans. Remember that all animals naturally have bacteria and viruses living in them which may cause us harm if we come into contact with them, so always wash your hands after handling any animals.
