Quick Comparison

NexGard Chewables

Tagline: A tasty beef-flavoured chew that starts killing fleas fast.

NexGard remains a top choice among Canadian vets for dogs. The active ingredient, afoxolaner, begins working within 4 hours of ingestion, and it's effective against both fleas and ticks, including the deer tick that can transmit Lyme disease. The monthly chew is easy to give—most dogs gobble it up like a treat. On the downside, it's pricier than some topical options, and it doesn't repel mosquitoes. Also, some dogs may experience mild vomiting or loose stool. Best for dogs that hate spot-on treatments and owners who want reliable, fast protection. Pricing varies by weight and retailer, but expect around $55 to $80 per chew.

• Pros: Fast-acting, palatable, vet-recommended
• Cons: Pricey, no mosquito repelling, possible GI upset
• Best for: Dogs that dislike topical applications
• Pricing snapshot: Approx. $55–$80 per dose, monthly

Revolution Plus for Cats

Tagline: All-in-one topical protection for cats that covers fleas, ticks, and heartworm.

Revolution Plus is a game-changer for cat owners. It combines selamectin and sarolaner to kill fleas, ticks, ear mites, and heartworm—all in one monthly dab. The formula is safe for kittens as young as 8 weeks, and it's water-resistant once dry. The main drawback is that it requires a prescription from your vet in Canada, so you'll need an exam first. Some cats dislike the sensation of the liquid on their neck, but most tolerate it well. Best for multi-cat households or owners who want broad-spectrum protection without multiple products. Pricing: roughly $70 to $95 per dose, depending on size.

• Pros: Multi-parasite coverage, safe for kittens, water-resistant
• Cons: Rx needed, some cats resist application
• Best for: Cats needing comprehensive protection
• Pricing snapshot: Approx. $70–$95 per dose, monthly

K9 Advantix II

Tagline: Repels and kills fleas, ticks, and mosquitoes for active dogs.

K9 Advantix II is a topical solution that not only kills but also repels fleas, ticks, and mosquitoes—a big plus for dogs that spend lots of time outdoors in wooded or grassy areas. The formula uses imidacloprid and permethrin, and it starts working within 12 hours. It's waterproof after 24 hours. However, it's toxic to cats, so if you have feline housemates, keep them separate after application. Some dogs may experience skin irritation at the application site. Best for adventurous dogs in tick-heavy regions. Price: around $45 to $65 for a 4-pack, making it a solid value.

• Pros: Repels mosquitoes, waterproof, affordable
• Cons: Toxic to cats, skin irritation possible
• Best for: Outdoor dogs in tick-prone areas
• Pricing snapshot: Approx. $45–$65 per 4-pack

Bravecto Chewables

Tagline: One chew provides 12 weeks of protection—set it and forget it.

Bravecto is the go-to for owners who want to minimize dosing frequency. A single chew protects dogs for a full three months against fleas and ticks, including the brown dog tick and American dog tick. The active ingredient, fluralaner, works by targeting the nervous system of parasites. It's highly effective, but it's also one of the most expensive options upfront. Some vets have noted potential neurological side effects, though rare. Best for busy pet parents or those who travel frequently. Pricing: $65 to $90 per chew, but remember it covers 12 weeks, not one month.

• Pros: Long-lasting, convenient, effective
• Cons: Higher cost per dose, rare side effects
• Best for: Owners wanting fewer applications
• Pricing snapshot: Approx. $65–$90 per chew, every 12 weeks

Seresto Collar

Tagline: A non-chemical-smelling collar that works for 8 months.

The Seresto collar offers a hands-off approach: put it on your dog or cat and forget about it for up to 8 months. It uses imidacloprid and flumethrin to repel and kill fleas and ticks continuously. It's water-resistant and doesn't have a strong odour, which many owners appreciate. The downsides: some pets may develop skin reactions where the collar touches, and it's less effective in the final month. Also, if you have multiple pets, they might chew each other's collars. Best for owners who struggle with monthly applications. Price: $70 to $90 per collar, which breaks down to about $9–$11 per month.

• Pros: Long-lasting, odourless, easy to use
• Cons: Skin reactions possible, less effective near end
• Best for: Forgetful owners or pets that resist other methods
• Pricing snapshot: Approx. $70–$90 per collar

Frontline Plus for Dogs

Tagline: A classic topical treatment that still gets the job done on a budget.

Frontline Plus is a staple in flea and tick control. It combines fipronil and (S)-methoprene to kill adult fleas, eggs, and larvae, plus ticks. It's affordable and available over the counter at most Canadian pet stores. It's also safe for puppies from 8 weeks old. The main downside is that it doesn't repel, so your dog might still be bitten before the parasites die. Some fleas have developed resistance in certain regions, but for most, it remains effective. Best for budget-conscious owners with low to moderate flea pressure. Price: $40 to $55 for a 3-pack.

• Pros: Low cost, OTC, good for puppies
• Cons: No repelling, possible resistance
• Best for: Budget-friendly basic protection
• Pricing snapshot: Approx. $40–$55 per 3-pack

Credelio for Dogs

Tagline: A fast-acting chew that kills fleas in just 2 hours.

Credelio is a newer oral option that uses lotilaner to start killing fleas within 2 hours and ticks within 12 hours. It's given monthly and is safe for dogs as young as 8 weeks and weighing at least 2 kg. The chew is liver-flavoured, which most dogs love. On the flip side, it's not as widely stocked as NexGard or Bravecto, so you may need to order online. Also, it doesn't cover heartworm or other parasites. Best for dogs with heavy flea infestations that need quick relief. Pricing: $50 to $75 per dose.

• Pros: Extremely fast action, palatable
• Cons: Limited availability, no heartworm protection
• Best for: Dogs with active flea problems
• Pricing snapshot: Approx. $50–$75 per dose, monthly

How to Choose

• Oral vs. topical vs. collar: Oral chews are great for dogs that hate goo on their neck, but if you have cats, avoid permethrin-based topicals. Collars are low-maintenance but might cause skin irritation.
• Spectrum of protection: Some products only kill fleas and ticks, while others also repel mosquitoes or prevent heartworm. Consider your pet's exposure to different parasites.
• Duration of effect: Monthly treatments require remembering to dose, while Bravecto and Seresto last longer. Choose based on your schedule and pet's lifestyle.
• Safety for your household: If you have cats, dogs, or kids, check that the product is safe for all. For example, K9 Advantix II is toxic to cats.
• Budget per month: Break down the cost: a $70 collar that lasts 8 months is cheaper than a $70 monthly chew. Compare carefully.
• Vet recommendation: Always consult your vet before starting any new flea and tick treatment, especially if your pet has health issues or is on other meds.
