5 Common Dog Diseases

There are some common dog diseases that every pet owner should be aware of and take precautions to prevent. Some of the most common are Distemper, Kennel Cough, Heartworms, Leptospirosis, and Parvovirus.

There are vaccines that help keep your pet from getting many illnesses and diseases. Pets like children and adults humans need to have regular checkups to make sure they are current on vaccines and are not developing any health issues.


Leptospirosis is a bacterial infection that dogs sometimes get from spirochetes which enter the dog by penetrating their skin. They then spread in their body by traveling through their bloodstream. They then reproduce in their liver, kidneys, and their central nervous system. They even reproduce in their eyes and reproductive system.

Dogs mainly come in contact with this in wet areas or pastures. Some of the most common symptoms are shivering, weakness, lack of appetite, an increase in thirst and urination, vomiting, and diarrhea. If your dog shows any of these symptoms take them to a veterinarian as this can be passed on to humans, especially children.

Kennel Cough

A kennel cough or Bordetella infection is another common disease dogs often get. More than one source can cause it, but most often it is caused by coming in contact distemper, canine herpes virus, parainfluenza virus, canine reovirus. They catch a kennel cough from inhaling bacteria or virus particles down their respiratory tract.

One of the most prominent symptoms is a persistent cough that often sounds like a goose honking. They may also sneeze and have a runny nose. It is very contagious, and if you suspect your dog has it, they will need to see a veterinarian.


Heartworms is another serious condition dogs often develop. It is passed on to them by infected mosquitos. The infected mosquito with heartworm larvae will give your pet heartworm disease. It takes about seven months for the larvae to mature into adult heartworms.

Then they lodge in their heart muscle, lungs and begin reproducing more of them. They grow up to twelve inches long and have a life expectancy of five to seven years. Some animals have been known to have up to 250 worms in their system at a time. Your vet can give you medicine to prevent them developing and growing in the first place.


Distemper is another common disease for your pet. Unfortunately, there is no known cure for distemper.The only saving grace is the disease is not as common and contagious as the others dicussed here, and also, there is a vaccine to prevent them getting it in the first place.

Symptoms include high fever, watery discharges from the nose and eyes, followed by coughing, vomiting, and other symptoms. They may even have seizures and have paralysis. Prevention is key to keeping your pet healthy.


Parvovirus is also preventable by a vaccine. It is easily transmitted by anyone or animal that has come into contact with the virus through an infected dog’s feces. A veterinarian will diagnose parvovirus based on what symptoms your pet is experiencing and a test called ELISA test. Some breeds are higher at risk for this illness and include Rottweilers, Labs, Dobermans., German Shepherds, and some terriers.

The veterinarian can give your dog a vaccine called a 5 in 1, that prevents three out of five of the diseases talked about in this article.


Like any other carnivores, dogs are easily worn out by diseases. A mild bout is enough to render them frail, lethargic and disoriented, ultimately impairing their health and performance. It is therefore important to see a vet a soon as you suspect your dog is ailing,
