Summertime in Vancouver, BC means more than sunny patios and beach walks—it also means more mosquitoes. And those buzzing pests aren’t just after you—they’re a threat to your pet’s health, too. At Country Grove Veterinary Clinic, we want to help pet parents get proactive about mosquito-borne illnesses in pets.
From heartworm prevention for dogs to mosquito safety for cats, this guide breaks down how to protect your pet from summer’s sneakiest dangers.
Why Mosquitoes Are a Problem for Pets
Mosquitoes aren’t just annoying. A single bite can transmit parasites or viruses—some of which can be deadly.
Top concerns include:
- Heartworm disease (mainly in dogs, but also reported in cats)
- West Nile virus (rare but possible in animals)
- Allergic reactions and skin irritation
Even indoor pets can be exposed if mosquitoes get into the home.
Heartworm: The Biggest Risk for Dogs
Heartworm disease is caused by parasites transmitted through mosquito bites. Once infected, heartworms grow inside the heart, lungs, and blood vessels—causing coughing, lethargy, weight loss, and potentially heart failure.
Heartworm prevention in dogs includes:
- Monthly chewable or topical medications
- Annual testing to catch early signs
- Consistent year-round protection (yes, even in BC!)
Can Cats Get Heartworm?
Yes—but differently. Cats are not the primary host for heartworms, so the worms often don’t mature fully. However, even immature infections can damage lungs and cause symptoms like vomiting, coughing, or sudden collapse.
Unlike dogs, there’s no approved treatment for heartworm in cats, which makes prevention crucial.
How to Protect Pets from Mosquitoes
- Keep pets indoors during peak mosquito hours (dawn and dusk)
- Install screens on windows and doors to keep bugs out
- Use vet-approved preventatives consistently
- Dump standing water from bowls, buckets, or birdbaths
- Avoid using bug sprays with DEET or essential oils on pets—they’re often toxic
FAQ: Mosquitoes and Pets
Do indoor cats need mosquito protection?
Yes—mosquitoes can enter homes and bite pets, especially if windows are open or screens are damaged.
Is heartworm common in Vancouver?
While not as widespread as in some regions, cases do occur in BC. Prevention is safer and more affordable than treatment.
Can I use citronella candles around pets?
Use caution—many pets are sensitive to strong scents and fumes. Never let them ingest or touch citronella products.
