Why it costs what it does
Heartgard Plus comes as: monthly beef chew, three weight bands, given at home. A few things set the price:
- Dosing scales with body weight — bigger pets need bigger or multiple doses, so weight is the main price driver.
Cheaper alternatives to ask your vet about
Generic ivermectin/pyrantel chews (e.g., Iverhart) shave a few dollars; this category is already cheap — skipping doses to save money risks a four-figure heartworm treatment bill.
Never switch, split, or stop a prescription on your own — bring these options up at your next visit and let your vet make the call for your pet.

How we verify these prices
Prices aggregated 2026-06-11 from public retailer listings (Chewy Rx, Petco, Heartland Vet Supply, EntirelyPets Rx, BudgetPetCare, PetBucket), GoodRx coupon pages, manufacturer pages, and 2026 vet-cost guides. Vet-administered injectables (Librela, Solensia, Cytopoint, Adequan loading) use published clinic-price surveys because the drug is not sold direct to consumers. Ranges are medication-only unless noted; exam/administration fees are flagged separately. Prices move — re-verify before publishing figures on a page, and show the per-item verified date.
