Where do dogs get diseases?

Dogs can contract diseases from a variety of sources, both indoors and out. Many diseases are spread through contact with contaminated soil or water, while others are transmitted by insects such as fleas and ticks.

Dogs can also pick up diseases from other animals, either through direct contact or by coming into contact with their feces. In addition, some diseases can be contracted by eating contaminated food or drinking infected water.

Dogs can also get sick if they are exposed to toxic substances such as household cleaners or pesticides. By taking some simple precautions, such as keeping their dog’s vaccinations up to date and regularly deworming them, owners can help to reduce the risk of their pet contracting a disease.

Most common dog diseases

Below is a list of the most common dog diseases and how your dog can get them. With care, you can help your dog avoid contracting these potentially life-threatening diseases.

Canine Distemper

Another common disease is Canine Distemper Virus, which affects a dog’s respiratory and nervous systems. CDV is also highly contagious and can be fatal in severe cases.

Canine Distemper Virus comes from the same family of viruses that cause measles in humans. It is spread through contact with contaminated saliva, mucus, or feces from an infected animal.

The virus can also be spread through the air, which makes it particularly dangerous in kennel situations. There is no cure for CDV, and treatment focuses on relieving symptoms.

Dog flu

While the dog flu is often compared to the human flu, the two illnesses are caused by different viruses. Canine Influenza Virus (CIV) is the virus that causes the dog flu, and it is classified as an H3N8 virus.

This type of virus is most commonly found in horses, but it can also infect dogs. CIV was first identified in 2004, when an outbreak of respiratory illness occurred among racing greyhounds in Florida. Since then, outbreaks have been reported in more than 30 states.

The best way to protect your dog from the flu is to get them vaccinated. The vaccine is highly effective and can help to prevent your dog from becoming infected with CIV. However, even if your dog has been vaccinated, they may still be at risk of contracting the virus if they come into contact with an infected animal.

Therefore, it is important to be aware of the symptoms of the dog flu and to seek veterinary care if your dog becomes ill. With proper treatment, most dogs will recover from the illness within 2-3 weeks.


One of the most prevalent dog diseases is Canine Parvovirus or CPV. CPV is a highly contagious virus that attacks a dog’s gastrointestinal system and can be deadly if left untreated.

Parvo is a deadly virus that primarily affects puppies, though it can also infect older dogs. The virus is highly contagious and is spread through contact with infected feces. It can also be spread through direct contact with an infected animal, or by touching contaminated surfaces.

Once a dog is infected, the virus attacks the intestines, causing severe vomiting and diarrhea. If left untreated, Parvo can quickly lead to dehydration and death.

Puppies are particularly vulnerable to the virus due to their undeveloped immune systems, which is why it is so important to make sure they are up-to-date on their vaccinations. Adult dogs can also contract the virus, but their chances of recovery are much higher.

Treatment for Parvo typically involves intensive supportive care, including fluids and antibiotics. With early intervention and proper treatment, most dogs will recover from the virus. However, sadly, some puppies do not survive.

Ticks, Fleas, and Mange

Ticks, fleas, and mange are all external parasites that can affect dogs.

Ticks attach themselves to their hosts and feed on their blood, while fleas live off the skin and hair of their hosts. Mange is caused by a mite that burrows into the skin, causing severe irritation. All three of these parasites can cause a great deal of discomfort for dogs and can transmit diseases.

Ticks can transmit Lyme disease, while fleas can carry tapeworms. Mange is also highly contagious and can be passed from dog to dog.

Fortunately, there are many products available that can help to control these parasites. Spot-on treatments, shampoos, and collars can all be effective at preventing or treating infestations.


Dogs can get sick from fertilizers in a number of ways. First, they may ingest the fertilizer directly, either by eating grass that has been treated with fertilizer or by licking their own feet after walking on the treated ground.

Fertilizers can also be absorbed through the skin, so if a dog lies down on treated grass or soil, they may become sick. Dogs can also inhale fertilizer particles that are suspended in the air.

All of these routes of exposure can lead to sickness in dogs, ranging from mild gastrointestinal upset to more serious problems like liver damage. For this reason, it is important to keep dogs away from recently treated areas and to make sure that they are not exposed to fertilizer fumes. By taking these precautions, you can help keep your dog healthy and safe.

Fungal infections

Fungal infections are a common problem for dogs, particularly those with long or thick coats. The fungi that cause these infections thrive in moist, warm environments, making the inside of a dog’s ear the perfect breeding ground.

Dogs can also pick up fungal infections from contaminated surfaces, such as dirt floors or carpeting. Fungi can also be passed from dog to dog through close contact. Many types of fungi are harmless to dogs, but some can cause serious problems.

The most common symptom of a fungal infection is itchiness, but other signs can include redness, swelling, and hair loss. If your dog is showing any of these symptoms, it’s important to take them to the vet for a diagnosis.

In most cases, fungal infections can be treated with antifungal medications. However, some strains of fungi are resistant to these medications, so it’s important to get a professional opinion before starting any treatment.


Heartworm is a serious and potentially fatal disease that affects dogs. The disease is caused by a parasitic worm that lives in the heart and lungs of an infected animal. It is transmitted through the bite of an infected mosquito.

When a mosquito that carries heartworm bites a dog, the worm larvae are injected into the dog’s bloodstream. The larvae then travel to the heart, where they mature and reproduce. Left untreated, heartworm can cause serious damage to the heart and lungs, and can ultimately lead to death.

Fortunately, heartworm is preventable with regular medications. However, it is important to catch the disease early, as treatment can be difficult and costly. If you suspect that your dog may have heartworm, contact your veterinarian immediately.


Dogs can suffer from heatstroke just like humans. When their body temperature gets too high, it can damage their organs and even be fatal. It’s important to know the signs of heatstroke so you can take action quickly if your dog is in danger.

Symptoms include heavy panting, drooling, lethargy, diarrhea, and vomiting. If you see any of these signs, move your dog to a cool area and give them water to drink. You should also apply cool water to their skin, especially their footpads and under their armpits.

If they don’t start to improve within 30 minutes, take them to the vet as they may need further treatment. By being aware of the dangers of heatstroke and taking quick action if your dog is affected, you can help them stay cool and safe in the summer months.

Intestinal parasites

Dogs can pick up intestinal parasites from a variety of sources. The most common way is through contact with contaminated soil or feces. This can happen when a dog goes outside and sniffs around in areas where other dogs have defecated.

Parasites can also be passed on from mother to puppy during pregnancy or nursing. In some cases, dogs can even pick up parasites from infected prey animals.

Intestinal parasites can cause a range of symptoms in dogs, including weight loss, diarrhea, and vomiting. If left untreated, they can lead to malnutrition and even death. Fortunately, there are a number of effective treatments available for dogs who are infected with parasites. Your veterinarian can help you choose the best option for your pet.

Kennel cough

Kennel cough is a common infection of the upper respiratory tract in dogs. It is caused by a number of different viruses and bacteria, including Bordetella bronchiseptica, parainfluenza virus, and adenovirus. These organisms are spread through contact with contaminated surfaces or airborne droplets from an infected dog.

Kennel cough is often seen in shelters and boarding facilities, where dogs are housed in close quarters and have little opportunity to build up immunity to the viruses and bacteria that cause the disease.

The good news is that kennel cough is usually not serious and will clear up on its own within two to three weeks. However, if your dog does develop kennel cough, it is important to seek veterinary care to ensure that the infection does not progress to pneumonia or other serious complications.


Leptospirosis is a contagious disease that affects dogs and other animals. The disease is caused by a bacterium called Leptospira interrogans, which is found in contaminated water or soil. Dogs can become infected with leptospirosis when they drink contaminated water or come into contact with contaminated soil. The bacteria can also enter the body through cuts or abrasions in the skin.

Symptoms of leptospirosis include fever, muscle pain, loss of appetite, and increased thirst. If left untreated, the disease can lead to kidney failure and death.

Leptospirosis is treatable with antibiotics, but it is important to seek veterinary care as soon as possible if you suspect your dog may be infected. Dogs that recover from leptospirosis often have lifelong immunity to the disease.


Rabies is a virus that affects the nervous system of mammals. It is most commonly found in bats, coyotes, foxes, and raccoons, but can also infect dogs. The virus is typically spread through the bite of an infected animal and can cause severe neurological damage.

Symptoms of rabies include aggression, muscle spasms, paralysis, and seizures. If left untreated, rabies is almost always fatal.

In order to protect dogs from rabies, it is important to vaccinate them on a regular basis. Vaccination helps to create immunity against the virus, and can significantly reduce the risk of infection.

Additionally, dog owners should avoid contact with wild animals, and should contact a veterinarian if their dog is bitten by another animal. By taking these precautions, dog owners can help to keep their pets safe from this deadly disease.


Ringworm is a common fungal infection that can affect both humans and animals. The fungus typically grows on the skin, causing a red, itchy rash in the shape of a ring. In dogs, ringworm is often seen on the head, ears, and paws.

The good news is that ringworm is treatable and not dangerous. However, it is important to see a veterinarian if you think your dog may have an infection. Ringworm is highly contagious and can be passed to other animals and humans.

The best way to prevent ringworm is to practice good hygiene and avoid contact with infected animals. If you think you may have been exposed to ringworm, see a doctor right away. Early diagnosis and treatment are essential for preventing the spread of this common fungal infection.

Toxic plants

Dogs can get sick from eating toxic plants, just like people can. The symptoms they experience will depend on the type of plant they ate and how much they ate. For example, if a dog eats a small amount of a poisonous plant, they may only experience vomiting and diarrhea.

If they eat a larger amount, they may experience more serious symptoms such as seizures or difficulty breathing. Some dogs may even die from eating toxic plants. To keep your dog safe, it is important to learn which plants are poisonous and to keep them out of reach. You should also contact your veterinarian immediately if you think your dog has eaten a toxic plant.

What human diseases can dogs get?

While dogs are generally quite resilient to disease, there are a number of illnesses that they can contract from humans. The most common of these is the flu, which can cause symptoms such as fever, runny nose, and coughing in dogs.

Dogs can also catch respiratory infections, such as pneumonia, from close contact with infected humans. Additionally, dogs can contract skin diseases, such as ringworm, through direct contact with an infected person. In rare cases, dogs may even contract rabies if they are exposed to the saliva of an infected human.

The risk of contracting these diseases can be greatly reduced by vaccinating your dog and keeping them up to date on their shots. By taking these precautions, you can help keep your furry friend healthy and safe.

Benefits of vaccinating your pet

Vaccinations are an important part of keeping your dog healthy. They help to protect your dog from diseases that could make them very sick, or even be deadly. Vaccinations work by exposing your dog to a “weak” form of the disease, which helps their immune system to build up immunity to the disease.

There are several different types of vaccinations that your dog may need, depending on their age, health, and lifestyle. For example, puppies generally need to be vaccinated more often than adult dogs. And if your dog spends time around other dogs, they may need a “kennel cough” vaccine.

Talk to your veterinarian about what vaccines are right for your dog. vaccinating your dog not only helps to keep them healthy, but it also helps to protect other dogs from disease. When all dogs are vaccinated, it creates “herd immunity” which makes it harder for diseases to spread. So not only is vaccinating your own dog important, but it also plays a role in protecting the health of the whole dog population.


Diseases that dogs get can be contracted in a variety of ways. Understanding the most common ways diseases are spread will help you take steps to prevent your dog from becoming infected. One of the best things you can do for your pet is to keep them up-to-date on their vaccines and preventive care. This includes regular deworming, tick/flea prevention, and heartworm prevention.

Vaccines protect your dog against some of the most common and deadly diseases out there. Rabies is one such disease, and it is important to make sure your dog is vaccinated against it. Dogs can also contract serious diseases like distemper, parvovirus, leptospirosis, and more from contact with other animals or exposure to contaminated water or soil.

By taking preventive measures and vaccinating your dog, you can help keep them healthy and reduce the risk of them spreading diseases to other dogs.
