INTESTINAL PARASITES: THE HIDDEN PROBLEM MANY PETS HAVE

Not all parasites are easy to spot. Unlike ticks or fleas, intestinal parasites often live quietly inside the digestive tract, and many infected pets look healthy on the outside.

That’s why routine screening and prevention are such important parts of veterinary care.

How Pets Get Intestinal Parasites

Pets can become infected through everyday activities such as:

  • Sniffing or licking contaminated soil

  • Drinking unsafe water

  • Contact with feces

  • Hunting rodents or wildlife

  • Grooming dirty paws

  • Swallowing infected fleas

Puppies and kittens are especially vulnerable, but adult pets can be affected too.

Common Intestinal Parasites

Some of the most common parasites include:

  • Roundworms

  • Hookworms

  • Whipworms

  • Giardia

  • Tapeworms

Signs to Watch For

Some pets show no symptoms, while others may develop:

  • Diarrhea

  • Vomiting

  • Weight loss

  • Pot-bellied appearance

  • Scooting

  • Poor haircoat

  • Low energy

Why This Matters for Families

Certain intestinal parasites can be transmitted to people, especially children or individuals with weakened immune systems.

That makes prevention important not only for pets, but for households as well.

How We Prevent and Detect Them

We may recommend:

  • Routine fecal testing

  • Deworming based on age and lifestyle

  • Year-round parasite control

  • Prompt treatment if parasites are detected


Many pets with intestinal parasites appear normal. Regular testing and prevention help catch problems early and protect the whole family.

Fun Fact: One Parasite Can Produce Thousands of Eggs in a Single Day

Some intestinal parasites, such as roundworms, can produce thousands of microscopic eggs every day. These eggs are shed into the environment, where they can survive for long periods under the right conditions.
