Most Common Dog Diseases

June 29, 2021

Like humans, dogs also face many health-related issues that can be life-threatening if not treated immediately. Therefore, we'll be talking about some significant canine diseases, their causes, symptoms, and treatment. There are many illnesses and conditions that dogs face. Most of these ailments aren't known to us, which is a massive cause for concern. Additionally, being a dog owner requires the utmost knowledge about these aspects to give your dog a healthy life.


Caused by a virus that attacks the nervous system, rabies is a deadly disease found in dogs. The virus gets secreted in the saliva of some dogs. It is then transmitted to other dogs by a bite from an infected animal. One needs to be very careful with rabies because it is almost always fatal. Rabies-infected dogs can show symptoms like fearfulness, aggression, excessive drooling, trouble swallowing, or seizures. Since rabies can also be transmitted to humans and other mammals, it is necessary to look out for it at any given point. 

A dog vaccine for rabies is not required if you live in Singapore as the country has been rabies-free since 1953. 


The Leptospira bacteria is generally found in soil and water. Leptospirosis is a zoonotic disease which means it can be spread from animals to humans. If your dog is exposed to rivers, lakes, or streams and roaming on rural properties, there is a high risk for your dog to contract this disease.

The signs of leptospirosis vary from dog to dog. The common symptoms include fever, shivering, muscle tenderness, lethargy, and jaundice. 

Additionally, severe cases of this disease may develop into bleeding disorders, kidney failure, or lung disease. Leptospirosis is generally treated with supportive care and antibiotics. The current vaccines protect dogs for about 12 months, after which they will require another shot. Furthermore, avoiding any exposure to water bodies and other animals’ urine can help prevent infection.

Parvo is a highly contagious virus that is often transmitted to dogs. The ease by which this virus spreads among the canine population is astonishing. It spreads either by direct contact with an infected dog or by feces. Young, unvaccinated dogs between the age of six weeks to six months are at the highest risk. 

The symptoms of parvovirus include severe diarrhea, lethargy, anorexia, fever, vomiting, dehydration, or weight loss. It is a highly resilient virus that can survive indoors for up to 2 months. Moreover, it is also resistant to many disinfectants as well as cleaners. Hospitalization is necessary so that your canine can be placed in isolation and be provided with supportive care.

A dog vaccine for parvo is compulsory in Singapore.

Kennel Cough

Kennel cough is a highly transmissible infection of, usually, the upper respiratory tract. Kennel cough is common in puppies and has similar symptoms to viral infections like cold or flu. It isn't often a life threatening disease for the canine population. 

The best way to look after your dog with a kennel cough is to provide them plenty of water, rest, and good food. Moreover, you must not take them outdoors for walks. If the case has become severe, you must consult the vet, for further treatment .
