The Most Common Diseases & Infections in Dogs

Dogs are susceptible to a wide range of illnesses that can be spread by interacting with other animals or diseased dogs. Humans can occasionally spread diseases from dog to dog by handling or petting an affected animal or by letting dogs share beds, brushes, and other items. Vaccines can prevent the majority of them.
The following are some prevalent illnesses and ailments that affect dogs:


Canine distemper


A highly infectious virus is the cause of the fatal illness known as canine distemper. It is typically caught by dogs and puppies by airborne exposure (coughing or sneezing), though it can also be transferred through body fluids. Dogs with the infection often have vomiting, diarrhea, paralysis, runny eyes, fever, snotty noses, coughing, and seizures.
Thankfully, vaccinations can prevent canine distemper, even though it can be lethal.


Parvovirus is a highly transmissible and deadly illness that can be contracted via direct dog contact as well as by contact with contaminated objects, clothing, surfaces, and more. It takes a while for contaminated surfaces and things to become free of the virus, which makes removal challenging.
When the gastrointestinal tract is attacked, fever, vomiting, and severe, frequently bloody diarrhea are the symptoms. Medication and special care are needed to treat parvovirus. To stop the illness, there are immunizations available. Bacteria and viruses work together to cause Kennel Cough. It is easily transmitted by contact with an infected dog and is very contagious. Even though they may not exhibit any symptoms at first, dogs that have kennel cough can still spread the infection to other dogs. The most typical signs of this sickness are a dry, hacking cough and a runny nose. There exist vaccinations designed to stave off Kennel Cough. To learn more about how it can benefit your dog or puppy, speak with your veterinarian.

Kennel Cough


Saliva is the medium via which the viral infection known as rabies spreads. There is no cure for rabies once an infection has taken hold. Through animal bites from infected animals, it is spread. Seizures, paralysis, aggressiveness, and poor coordination are some possible symptoms.
It is advised to have the vaccinations as soon as possible in order to prevent rabies. Rabies is frequently lethal if treatment is delayed.


External parasites that attach themselves to animals, such as fleas, ticks, and mange, are the source of many diseases. When a human or dog is bitten by an infected tick, the disease is spread. Dogs can contract several different tick-borne illnesses; the most prevalent ones include Rocky Mountain Spotted Fever, Ehrlichiosis, Lyme disease, and anaplasmosis. Both people and dogs may experience major health repercussions if treatment is not received.
The easiest approach to avoid this is to make sure you take the necessary precautions (tick washes, medications, etc.) to ensure that dogs are free of parasites.

Tick-borne diseases


Dogs frequently experience severe pain and discomfort from ear infections or skin allergies. The main causes of these are bacteria, yeast accumulation in the ears, environmental factors, dietary problems, and allergies associated to fleas. Wailing, shaking of the head, pawing at the ears, and frequent biting or scratching of the skin are the most typical symptoms of allergies and infections.

It is always advisable to send your dog to the vet before the allergies or illness worsen, even though there may be more than one cause.


What is the first aid for a sick dog?

Take out all food and liquids. Look out for symptoms of dehydration. Get your pet checked out by a veterinarian if the vomiting, diarrhea, or other health issues persist. Start giving tiny amounts of clear liquids (water, Gatorade, Pedialyte, or another electrolyte solution) periodically if vomiting doesn’t happen for six to eight hours.

How do I make my sick dog happy?

Ill dogs require a lot of rest and sleep. Make sure your dog has a peaceful, comfortable space to unwind in where there won’t be any distractions from other animals or young children. To make sure your ill dog is left alone, you might wish to keep them in a separate room or part of the house.

What is the main disease for dogs?

Microscopic mites are the cause of the parasitic skin disorder known as mange. This skin condition in dogs is brought on by two distinct mange mites. Sarcoptic mange, which is found immediately beneath the skin’s surface (for additional details, refer to the handout “Sarcoptic Mange in Dogs”), and demodectic mange, which is found inside the hair follicles, are two different types of mange.
