Protecting Your Pet From Parasites Year-Round

At Firth Veterinary Hospital, your trusted veterinary clinic and animal hospital in South London, ON, we believe prevention is the best form of protection—especially when it comes to parasites. Fleas, ticks, and heartworms don’t just make your furry friend uncomfortable. They can lead to serious health problems, some of which are life-threatening.

If you’ve ever searched “vet near me” in a panic after spotting a tick or wondered whether year-round heartworm meds are necessary, you’re in the right place. Our veterinarians are here to break it all down: what these parasites do, how to prevent them, and what you can do to keep your pup or kitty safe and healthy all year long.

Fleas: Tiny Pests, Big Problems

Why Fleas Are More Than a Nuisance

Fleas can cause intense itching, skin infections, and allergic reactions. In severe cases, especially in puppies or kittens, a heavy infestation can lead to anemia. Fleas also carry tapeworms—an unpleasant parasite, to say the least.

Signs Your Pet Has Fleas

• Constant scratching or licking 
• Hair loss, especially around the tail or neck 
• Black “flea dirt” specks in the fur 
• Irritated or red skin 

Flea Prevention Tips

• Use vet-approved monthly flea preventives 
• Keep bedding clean and vacuum carpets regularly 
• Treat all pets in the household—even indoor cats 
• Stay consistent, even during cooler months 

Ticks: Small But Dangerous

What Ticks Can Do

Ticks are more than just gross—they carry diseases like Lyme, Ehrlichiosis, and Anaplasmosis. Some tick-borne illnesses can become chronic and affect your pet’s joints, kidneys, or nervous system.

Ticks are especially common in wooded or grassy areas, but they can show up in suburban backyards too—especially in South London, ON where the climate is tick-friendly.

How to Spot Ticks on Your Pet

• Feel for small, hard bumps during grooming 
• Check ears, armpits, toes, and around the collar 
• Use a fine-tooth comb for thorough inspections 

Tick Prevention Tips

• Use year-round tick preventives (many flea products cover ticks too) 
• Avoid high grass or heavy brush during walks 
• Check pets thoroughly after outdoor play 
• Remove ticks promptly with a tick remover or tweezers (never bare hands) 

Heartworms: Invisible and Deadly

How Heartworms Spread

Heartworms are transmitted through mosquito bites. Once inside your dog—or rarely, your cat—the larvae travel through the bloodstream, growing into foot-long worms that live in the heart and lungs.

Sadly, dogs often show no symptoms until the infestation is advanced, making early detection critical.

Symptoms of Heartworm Disease

• Persistent coughing 
• Fatigue or exercise intolerance 
• Weight loss 
• Labored breathing 

In cats, symptoms may mimic asthma or go unnoticed until a sudden collapse. Heartworm disease in cats is much harder to treat, which is why prevention is key.

Heartworm Prevention Tips

• Give monthly preventives year-round (oral, topical, or injectable) 
• Schedule annual heartworm tests for dogs 
• Keep your home and yard mosquito-free 

At Firth Veterinary Hospital, we offer a range of trusted preventives and personalized advice. If you’re unsure which product is right for your four-legged buddy, just ask.

Common Misconceptions About Parasite Prevention

“My pet is indoors, so they’re safe.”

Not true! Fleas and mosquitoes can come inside, and ticks can hitch a ride on humans or other pets.

“I only need to treat during summer.”

Parasites are more resilient than you may think. Many survive mild winters or lay dormant until spring. Year-round prevention is the safest strategy.

“I don’t see any symptoms, so my pet must be fine.”

Many parasites cause subtle or delayed symptoms. Preventive care is about staying ahead, not reacting after the fact.

FAQs

How often should I give parasite preventives?

Most products are monthly, but some last 8–12 weeks or longer. Our veterinarians will recommend a schedule based on your pet’s needs.

What’s the safest flea and tick product for my dog or cat?

It depends on your pet’s age, weight, health, and lifestyle. Never use a dog product on a cat, or anything that isn’t vet approved. We’ll help you choose the safest option. 

Is heartworm prevention necessary year-round?

Yes! Heartworm risk doesn’t disappear in the winter, especially in warmer climates. Continuous protection is best.

Can my indoor cat get heartworm?

Yes. While less common, cats can get heartworm from a single mosquito bite—and there’s no safe treatment for kitties. Even one worm can be fatal to them. Prevention is critical.

How do I remove a tick safely?

Use tweezers or a tick remover tool to grasp close to the skin. Pull straight out slowly—don’t twist. Disinfect the area and wash your hands.
