Small Dog Diseases

Small Dog Diseases  by Janice Jones  |Last Updated 07-28-2021

No one likes to see their small dog suffering and when it turns out that your dog has a serious illness, a rush of emotions may overwhelm you.  Confusion, despair, worry, fear, and panic are just a few feelings that many people report.

The good news is that small dogs generally live longer than their larger cousins and most enjoy a relatively healthy life. Many of the diseases we see in older small breed dogs are due to their longevity.  These same diseases such as cancer, heart disease, diabetes and kidney failure are also common in older people.

The bad news is that some problems result because of their small size and physical structure.  There are also some diseases with a genetic component that are common in small breed dogs.

This page is a database of some of the most common ailments.  Click on any link to go to an article about the description, causes, symptoms, treatment options.  It is always easier to deal with small dog diseases if you have some understanding.

Dog Infectious Diseases

Keep in mind that all dogs are susceptible to infectious diseases such as Parvo, all dogs can get worms, and all dogs can be bothered by external parasites such as fleas and Ticks.  In fact there are at least 6 if not more preventable dog diseases that no dog should ever get.

These issues are common in all dogs and can be prevented through yearly veterinary exams, vaccinations, wormings, and external parasite control. 

Keep your small dog healthy with these simple pet health tips.

Can Your Dog Make You Sick?

Most small dog diseases can not be passed onto people, but there are some that you should know about, namely zoonotic diseases. Zoonotic diseases are caused by germs that can pass between people and animals.  They can spread in two ways:  Direct and Indirect Transmission.  

Direct transmision means that there is direct contact with some form of bodily fluid such as saliva, blod, urine or feces.  Indirect contact means that germs are spread by coming into contact with a contaminated surface such as a dog bed, food and water bowl, or soil and grass where germs remain hidden.

The Centers for Disease Control and Prevention (CDC) explains 3 ways that people or animals contaminate each other including water, food, and through a vector such as a flea, tick, or mosquito.  Eating unsafe or contaminated food is a common way a person may get sick.  Drinking or coming into contact with contaminated water is the other way a person or pet can get sick.

Here is a list of common zoonotic diseases that can pass from dogs to people.  Note that these diseases can be passed by dogs of all sizes, not just small breed dogs.

  • Rabies
  • Giardia
  • Ringworm
  • Leptospirosis
  • Lyme Disease
  • Roundworms
  • Hookworms
  • Tapeworms
  • Scabies

Small Dog Diseases & Health Problems
