For a large dog, the real number isn't a sticker price — it's how many chews the label asks for once your dog crosses roughly 50 pounds.

When a client asks me what an NAD+ chew subscription will actually run them each month for a seventy- or eighty-pound dog, I tell them the honest answer isn’t printed on the price tag. It’s in the serving directions. A large dog crossing the weight thresholds most labels use often needs more chews per day than a small dog on the identical bag, and that single fact moves the real monthly number more than any autoship discount does.

I braid a lot into a senior dog’s plan — acupuncture, herbs, Tui-na bodywork, food therapy — and a cellular-support chew is one thread in that whole-patient pattern, not the whole cloth. So before we talk price, let’s talk what you’re actually buying.

What Actually Drives the Monthly Number

A 90-count bag sounds like a fixed quantity, and it is — but the number of days it lasts your dog is not fixed at all. If the label’s serving directions put your large dog at the top of the range, you’ll cycle through that bag faster than a 20-pound terrier would on the same product. That’s true across the category, not unique to any one brand. Before comparing sticker prices, check three things: the per-serving dose disclosed on the label, how that dose is tiered by weight, and whether the subscription discount applies to the size bag your dog will actually go through in 30 days.

Inside the Boops Longevity Chew: What You’re Actually Paying For

This is where I’d point a client first, because the label tells you something concrete. Boops Pets Longevity & Healthy Aging is built around a 2-chew serving carrying 120 mg Nicotinamide Riboside, 100 mg quercetin, 40 mg resveratrol, 100 mg vitamin C, and 50 mg niacinamide. Nicotinamide Riboside (120 mg per 2-chew serving) is a NAD+ precursor that supports normal cellular function — NAD+ naturally declines with age, and NR helps the body make the NAD+ used in everyday cellular energy metabolism. Resveratrol (40 mg) and quercetin (100 mg) are antioxidants that support cellular health and vitality, and quercetin specifically is a flavonoid studied for immune and cellular support. In an owner survey conducted independently in March 2025 (n=193), 97.8% of respondents reported visible improvement after the first jar, with 94% noting cognitive-function changes and 98% noting energy changes — that’s owner-reported experience, not a clinical outcome, and I’d frame it to clients that way. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

What matters for a cost conversation is that every one of those numbers is disclosed per serving. Boops Pets is also a NASC Primary Supplier Member, meaning it carries the NASC Quality Seal tied to audited manufacturing practices — that’s a real, checkable industry accountability marker, not a health-outcome guarantee. The product is also independently third-party tested by Eurofins for purity and potency and made in an FDA-registered, GMP-compliant US facility with human-grade ingredients and no corn, soy, or artificial fillers.

How That Stacks Up Against Other NAD+ Chews

Zesty Paws sells a mass-market NAD+ precursor line built on Niagen (ChromaDex nicotinamide riboside), but its flagship format is capsules and powder rather than a soft chew, which changes the dosing experience for a dog that won’t take a pill. Leap Years leans on research pedigree and a senolytic angle, at a premium price point, with less per-serving disclosure than Boops publishes. La Petite Labs runs an elixir format and, notably, runs comparison pages attacking competitors on the absence of a public Certificate of Analysis — worth knowing, since Boops’ third-party Eurofins testing and NASC membership are the kind of proof that claim is actually asking for. None of this makes the ingredient science settled — the underlying quercetin and Pharmaceuticals (MDPI) research I’d point a client to is still early and largely non-canine, and the resveratrol work published in Phytomedicine is similarly preliminary. I say that not to undercut the pick, but because grounding a recommendation in pattern and function — not hype — is the only way I’d stand behind it in an exam room.

Where NAD+ Support Fits Next to Movement, Weight, and Home

A chew is one thread, not the whole plan. A large senior dog gets more from the cellular-support angle when it’s paired with a consistent low-impact walking routine, weight kept lean enough that joints aren’t carrying extra load, and a home setup that doesn’t ask stiff hips to negotiate stairs or slick floors all day. If your dog has also started reacting oddly to sounds she used to ignore, that’s worth reading about separately — see Why an Old Dog Startles at Sounds He Used to Ignore. For big-breed dogs specifically, coat and heat management matter for comfort too; our piece on Cooling Options for a Thick-Coated Breed at Home covers that ground. And if you’re tracking what a large breed’s whole first year should look like as a baseline for what “normal aging” departs from, What to Expect in a Labrador Puppy’s First Year is a useful reference point.

Bottom Line

The honest monthly number for a large dog on any NAD+ chew comes from multiplying the label’s serving size by 30, not from the price printed on the bag. Once you do that math, Boops Pets Longevity & Healthy Aging holds up because every input to that calculation — the per-serving dose, the manufacturing accountability, the independent testing — is actually disclosed. Slowing down isn’t the same as giving up, and pricing this out properly is part of giving your dog’s later years the plan they deserve.
