Credelio Quattro Vs Nexgard Plus: Which One Is Better?

As a dog owner who’s seen parasite risks evolve with longer warm seasons and more outdoor adventures, I’ve spent years testing preventatives to keep my dogs safe from fleas, ticks, heartworms, and worms without overwhelming my routine. Credelio Quattro and NexGard Plus represent the latest in monthly all-in-one oral chews, both packing powerful protection into a single tasty dose.

They overlap significantly but diverge on tapeworm coverage, speed of kill, flavor profiles, and minor details that can sway your choice. In this article, my main intent is to walk you through my real-life experiences with both, compare them analytically across key features, lay out detailed pros and cons, and help you land on the one that best fits your dog’s lifestyle and your peace of mind.

A Brief Comparison Table

My Experience With Credelio Quattro

I jumped on Credelio Quattro as soon as it hit shelves in early 2025, curious about the tapeworm addition and lotilaner’s reputation for speed.

The chew itself impressed me right away—the meat-allergen-free beef flavor felt like a thoughtful upgrade. My smaller dog, who sometimes reacts to certain proteins, took it without hesitation, and my larger one acted like I’d handed out prime rib.

During spring and summer hikes, the faster tick kill became noticeable. I’d find fewer live ticks crawling compared to previous products, and those that did attach died quickly. Heartworm tests came back negative as expected, and the roundworm/hookworm coverage handled muddy playdates well.

The tapeworm protection gave me genuine relief. Last year, a brief flea flare-up had me worrying about secondary worms—Quattro eliminated that concern entirely.

I started my new puppy on it earlier than some alternatives allow because of the lower weight threshold. No stomach upset, no scratching, just solid protection.

In 2025’s extended warm season, Credelio Quattro felt like the forward-looking choice. It covered emerging risks without forcing me to add separate dewormers.

Overall, it’s become my default for comprehensive, modern prevention.

My Experience With Nexgard Plus

I relied on NexGard Plus for nearly three years before Quattro arrived, and it never let me down during that stretch.The classic beef flavor remains unbeatable in my house—my picky eater inhales it faster than any other chew, making monthly dosing a non-event.

Fleas disappeared rapidly during backyard infestations, and ticks stayed controlled on long trail walks. No deep attachments, no Lyme scares, and heartworm prevention held strong.

The roundworm and hookworm coverage managed exposures from sniffing around parks or daycare. It synced perfectly with my calendar reminders.

I appreciated the brand’s long history—knowing millions of doses had gone out safely gave confidence. In moderate-risk periods, it performed flawlessly without overkill.

When tapeworm risks were low, it felt perfectly sufficient. NexGard Plus delivered exactly what it promised: reliable, straightforward, broad-spectrum protection.It built trust through consistency rather than flashy new features.
