Nexgard Spectra vs Simparica Trio: Cost and Coverage Differences in Calgary

Nexgard Spectra and Simparica Trio are two of the most commonly discussed combination parasite preventives for dogs in Calgary vet clinics. Both are prescription-only, both are monthly chewables, and both cover more than one parasite. That is where the similarities end, and where the questions usually start for owners trying to plan a household budget.

This article compares the two on structure, coverage categories, and the factors that shape the cost. It does not declare a winner, recommend one over the other, or provide dosing. Product selection stays with your veterinarian.

How combination parasite preventives work

Combination products bundle multiple active ingredients into a single monthly dose. That usually means fewer products to buy, fewer schedules to track, and one consistent monthly routine. The trade-off is that the exact mix of coverage varies from product to product, so what looks like a similar chewable can actually cover a different set of parasites.

What Nexgard Spectra covers at a glance

Nexgard Spectra is a monthly chewable that pairs an isoxazoline-class parasiticide with a second active ingredient targeting internal parasites. Broadly, it addresses:

• Fleas
• Multiple tick species
• Heartworm prevention
• Certain intestinal worms

The specific parasites and claims on the Canadian label are what your veterinarian will refer to when deciding whether it fits your dog.

What Simparica Trio covers at a glance

Simparica Trio is also a monthly chewable combining an isoxazoline with additional active ingredients. Its coverage typically includes:

• Fleas
• Multiple tick species
• Heartworm prevention
• Certain intestinal worms

Again, the Canadian label is the reference point your vet uses.

Side-by-side coverage comparison

At a high level, both products aim at the same broad job: single-chewable, monthly, multi-parasite protection. The differences show up in specific claims, tick species covered, minimum age and weight, and how each product behaves in real households.

Category	Nexgard Spectra	Simparica Trio
Format	Monthly chewable	Monthly chewable
Fleas	Yes	Yes
Ticks	Yes, multiple species	Yes, multiple species
Heartworm	Yes	Yes
Intestinal worms	Yes, per label	Yes, per label
Weight bands	Multiple	Multiple

Your veterinarian will translate the label details into a decision that fits your dog's weight, age, and health status.

What shapes the price in Calgary

Pricing for both products depends on several factors that are more important than the shelf label alone.

• Weight band. Both come in dose sizes tied to your dog's weight.
• Pack size. Longer supplies are usually less expensive per dose than a single month.
• Fulfillment channel. Clinic pickup pricing and prescription delivery pricing are often different.
• Currency and supply. Canadian availability and wholesale pricing shift periodically.

How weight bands affect your monthly cost

Both products are dosed by weight, so a 40 kg dog will not pay the same as a 10 kg dog. If you are budgeting for a growing puppy, expect the monthly cost to change as they move into a new weight band. Your vet will confirm the appropriate dose at each visit.
