Tick Prevention for Outdoor Cats and Dogs in Richmond, BC: A Local Vet's Guide

If you’ve ever come back from a walk along the Steveston dyke or Iona Beach and wondered whether you should be checking your dog for ticks, the short answer is yes — and you’re far from alone in asking. The same goes if you have a cat who spends time outdoors, whether that’s roaming the neighbourhood or lounging in a backyard bordered by tall grass. It’s one of the most common questions we get at Petsville Animal Hospital each spring.

The good news: tick-borne disease risk in BC is genuinely lower than in most of Canada. The catch: low risk isn’t no risk, and a single bite can still cause real problems for dogs and outdoor cats alike. Here’s what every Richmond pet owner should know about tick prevention this season — what’s actually a concern locally, what isn’t, and what to do if you find one on your dog or cat.

Are Ticks Really a Problem for Dogs and Outdoor Cats in Richmond?

Yes, for both. Richmond and the wider Lower Mainland sit inside one of BC’s identified tick habitat zones, according to BC Centre for Disease Control surveillance data. While we don’t have the dense tick populations of eastern Canada, our coastal climate — mild, damp, with plenty of grassy and wooded edge habitat — is exactly what ticks like, and it doesn’t distinguish between a dog on a leash and a cat exploring the yard.

There are two species local pet owners are most likely to encounter:

• The Western black-legged tick (Ixodes pacificus) — concentrated in the Lower Mainland and on Vancouver Island. This is the species that can carry the bacteria responsible for Lyme disease.
• The wood tick, also called the dog tick (Dermacentor andersoni) — the most commonly submitted tick in BC overall, and despite the name, it will bite cats too. It does not carry Lyme disease, but its bite can still cause local skin infections, irritation, and rarely, tick paralysis.

Tick activity peaks from April through July, with a second smaller surge in early autumn. Because BC’s south coast stays mild through the winter, ticks here can remain active in any month — they don’t fully shut down the way they do in colder climates.

Where dogs and outdoor cats typically pick up ticks in Richmond

If your dog or cat spends time in any of these spots — or even just an unmowed corner of the yard — tick checks should be part of your routine:

• Iona Beach Regional Park
• Garry Point Park
• The Steveston and West Dyke trails
• Richmond Nature Park
• Terra Nova Rural Park
• Any tall grass, leaf litter, or shrubby trail edge along the Fraser River — including residential yards backing onto green space

Ticks don’t jump or fly. They wait on grass tips and low vegetation for a host to brush past — which means dogs running through anything taller than a manicured lawn, and cats who roam or nap in that same kind of vegetation, are equally good targets.

Should You Worry About Lyme Disease in BC?

This is the question we get asked most, and we want to give you a straight answer: the risk is real but low for dogs, and even lower for cats.

Here’s the honest picture, drawn directly from BCCDC surveillance:

• Fewer than 1% of ticks tested in BC carry the bacteria that causes Lyme disease — compared to infection rates of 20% or higher in northeastern North America.
• BC reports somewhere between 6 and 39 confirmed Lyme disease cases per year in dogs, and most of those are linked to travel outside the province. Clinical Lyme disease is rarely diagnosed in cats at all — they appear to be naturally resistant to showing symptoms even when infected.
• The Western black-legged tick is also a less efficient Lyme vector than its eastern cousin, and BC’s local rodent and lizard hosts (including the Northern alligator lizard) actually reduce the bacteria’s spread compared to eastern ecosystems.

So no — your dog or cat is not in serious Lyme danger every time they’re outside. But “low risk” isn’t a reason to skip prevention, for three reasons:

1. Other tick-borne diseases exist. Anaplasmosis and babesiosis are also carried by BC ticks and can affect both dogs and cats, so exposure isn’t limited to Lyme.
2. Tick bites cause problems regardless of disease. Skin infections, abscesses, and irritation at the bite site are common — and uncomfortable — in either species.
3. Travel changes the math. If you visit Vancouver Island, head east of the Rockies, or take your pet into the US, exposure to higher-risk tick populations goes up sharply.

A Three-Layer Approach to Tick Prevention

Effective tick prevention isn’t one product — it’s three habits working together, for dogs and outdoor cats alike.

1. Year-round veterinary preventative medication

The single most effective layer. Modern tick preventatives fall into three main categories:

• Oral chewables — taken monthly or every three months, with formulations available for both dogs and cats. They kill ticks after attachment, before disease transmission is likely.
• Topical spot-ons — applied to the skin between the shoulder blades, monthly. Effective but can be affected by bathing or swimming.
• Tick collars — long-acting (up to 8 months) and useful as a backup or for pets who can’t tolerate oral medication.

A critical safety note for cat owners: never use a dog flea or tick product on a cat unless the label explicitly states it’s safe for cats. Many dog formulations contain permethrin, which is highly toxic — even fatal — to cats. Always check with us about which product is labelled and dosed correctly for your cat’s species, weight, and lifestyle before applying anything.

Which product is right for your pet depends on their species, age, weight, lifestyle, swimming and bathing frequency, and any existing health conditions. We’ll go through the options with you at your next visit. In our coastal climate, year-round prevention is the right default for dogs and outdoor cats alike, not just seasonal coverage.

2. Habitat awareness and post-outing tick checks

After every walk through grassy or wooded areas — or any time your cat comes back in from outdoor roaming — run your hands over them from nose to tail, paying extra attention to:

• Around the collar and under the ears
• Inside the ear flaps
• Between the toes and around the paw pads
• Armpits and groin
• Along the belly and base of the tail

A thorough check takes about two minutes and catches most ticks before they latch on. Brushing your dog or cat after they’ve been in long grass or wooded areas helps too, and doubles as a good bonding routine for cats who might otherwise resist handling.

3. Yard and home management

• Keep grass mowed short
• Clear leaf litter, especially under decks and along fences
• Discourage rodents — deer mice are the primary reservoir host for tick-borne bacteria in BC, and outdoor cats who hunt them face extra exposure
• Consider creating a wood chip or gravel border between lawn and any wooded edges

Signs Your Dog or Cat May Have a Tick-Borne Illness

Symptoms can appear weeks — or even months — after the bite, and many pets were never seen with a tick attached at all. Cats are especially good at hiding illness, so subtle changes matter just as much as obvious ones. Watch for:

• Lethargy or unusual tiredness
• Lameness that shifts between legs (a classic sign in dogs)
• Fever
• Loss of appetite
• Swollen joints or lymph nodes
• Reluctance to move or jump
• In cats specifically: hiding more than usual, or a drop in grooming and activity

Any of these symptoms warrant a same-day appointment, especially if your pet has been in tick habitat in the past few months. Tick-borne disease is highly treatable when caught early.
