Weigh your dog to confirm — if they’re over 50 lbs, switch to the Brown pack.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a heartworm test before starting?\u003c\/strong\u003e\u003cbr\u003eFor puppies starting before 7 months of age, no test is typically needed. For older dogs being newly started on heartworm prevention, your vet may recommend a heartworm test first — standard veterinary practice across the US and Canada.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes HeartGard Plus cover fleas, ticks, or tapeworm?\u003c\/strong\u003e\u003cbr\u003eNo — HeartGard Plus only prevents heartworm and treats roundworm and hookworm. For flea and tick prevention, pair it with NexGard, Bravecto, or another flea\/tick product. For tapeworm, you’ll need a separate wormer (or a product like NexGard Spectra that includes tapeworm coverage).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow quickly does HeartGard Plus start working?\u003c\/strong\u003e\u003cbr\u003eHeartGard Plus works by killing immature heartworm larvae that have infected your dog within the previous 30 days. Continuous monthly dosing maintains the protective cycle — that’s why year-round dosing matters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a prescription to buy HeartGard Plus?\u003c\/strong\u003e\u003cbr\u003eNo — SmartWay Pet Supplies ships HeartGard Plus \u003cstrong\u003eover the counter\u003c\/strong\u003e to customers across the US and Canada.

Mosquitoes that transmit heartworm are active for more of the year than people realize, and missed doses can leave dangerous gaps in protection. The American Heartworm Society recommends year-round dosing for all dogs.\u003c\/p\u003e\n\u003ch3\u003eHelpful Links\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/heartgard-plus\"\u003eShop the full HeartGard Plus range\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/dog\"\u003eShop all dog parasite prevention\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eFast shipping across the US \u0026amp; Canada — no prescription required.
