Dog and Cat Parasites in Spring: Symptoms, Prevention, and Treatment

What Every Pet Parent Needs to Know This Season - by Dr. Jake Smiley

Spring in Northern Virginia means more time outside with your pets… and a higher risk of parasites.

As temperatures rise, fleas, ticks, and intestinal parasites become much more active. That puts both dogs and cats at risk, even if they spend most of their time indoors.

In this week’s Vet Video Series, Dr. Jake Smiley explains how parasites affect pets, what symptoms to watch for, and how to prevent them before they become a bigger problem.

Why Parasites Are More Common in Spring

Warmer weather and increased humidity create the perfect environment for parasites to thrive.

During the spring and summer months, we see a significant increase in:

  • Fleas on dogs and cats
  • Ticks that carry diseases like Lyme disease
  • Intestinal parasites such as roundworms, hookworms, and giardia

Pets can pick up parasites from grass, soil, other animals, or even inside your home.


Common Dog and Cat Parasites

At Town and Country Animal Hospital, these are the most common parasites we diagnose:

Fleas in Dogs and Cats

Fleas are one of the most common external parasites. They cause itching, skin irritation, and can lead to tapeworm infections.

Ticks and Tick-Borne Diseases

Ticks attach to your pet and can transmit serious diseases, including Lyme disease and ehrlichiosis.

Intestinal Parasites in Pets

Roundworms, hookworms, whipworms, and giardia are common intestinal parasites that can affect both dogs and cats. Many pets show no symptoms early on.


Symptoms of Parasites in Pets

Some pets show clear signs, while others may not show symptoms right away.

Common symptoms include:

  • Scratching or biting at the skin
  • Hair loss or skin irritation
  • Diarrhea or soft stool
  • Vomiting
  • Weight loss
  • Low energy

Because symptoms are not always obvious, routine testing is essential.


How We Diagnose and Treat Parasites

Early detection is key to protecting your pet’s health.
