For 50-100+ lb frames
A 90-pound puppy isn't a big small dog.
Weight rewrites the entire joint-development timeline: a frame maturing to 50-100+ lb builds more joint, over a longer window — growth plates can stay open past 18-24 months — with adult-sized weight arriving before the joints are finished. MoveGuard Growth is 9 vet-reviewed actives dosed by expected adult weight for the full 8-30 month build.

The size story
5 things every big-dog parent should know about growing joints
A 90-pound puppy isn't a big small dog. Size rewrites the entire joint-development timeline — here's what that means for the next two years.
Big dogs finish growing years after small dogs do
A Chihuahua is essentially done building its skeleton by 6-8 months. A Labrador keeps developing toward 18 months. A Great Dane or Mastiff keeps going toward 24 months — and giants can continue filling out toward 30. That's not a detail; it's a completely different project. Your big pup spends two to four times longer in the joint-building phase than a small dog, which means the season for supplying daily structural support is dramatically longer too. MoveGuard Growth is dosed for that full 8-30 month season rather than the compressed timeline generic formulas assume.
Supported by: NZ Green-Lipped Mussel & MSM
The weight arrives before the joints are finished
Here's the size paradox: a giant-breed adolescent can weigh 80-100+ pounds — a full adult's mass — while its joints are still months from maturity. Large breeds hit roughly 85% of their adult height by 12 months, but the joint surfaces, cartilage and connective tissue underneath keep maturing long after the scale stops being impressed. Adult-sized load on still-forming joints is the defining mechanical reality of big-dog puppyhood, and it's why cushioning and resilience support matter every single day of it.
Supported by: Hyaluronic Acid, Chondroitin & NZ Green-Lipped Mussel
Growth plates stay open longest in the biggest dogs
Growth plates — the soft zones where bone lengthens — close around 6-8 months in tiny breeds, 14-18 months in large breeds, and as late as 18-24 months (sometimes beyond) in giants. While they're open, the tissue around them is comparatively soft, flexible and actively under construction. An open growth plate is the clearest possible signal that the building isn't done: the skeleton is still laying down new cartilage and bone, and the recognized structural building blocks are exactly what that construction draws on.
Supported by: Glucosamine, Chondroitin & Manganese
A bigger skeleton simply needs more raw material
A Newfoundland builds roughly ten times the skeleton of a terrier — more bone, more cartilage surface, more tendon and ligament, all assembled from nutritional raw material. The body sources those building blocks from what you feed it, every day, for the entire runway. Supplying recognized cartilage and connective-tissue precursors daily means the construction site never waits on materials. It's the same logic as any big build: the bigger the structure, the more the supply chain matters.
Supported by: Glucosamine, MSM, Vitamin C & Manganese
Support should scale with the dog — which is why dosing by adult weight matters
A 55-pound Golden-to-be and a 140-pound Dane-to-be are not the same project, so they shouldn't get the same serving. MoveGuard Growth doses by expected adult weight — 2 chews a day for dogs maturing to 50-80 lb, 3 a day for 80-100+ lb — so the support is scaled to the frame actually being built, not to a one-size-fits-all average. Combined with the 8-30 month window formulation, that's support matched to both the size of the build and the length of the build. Big dogs get a formula that respects the fact that they're big.
Supported by: Antarctic Krill Oil, NZ Green-Lipped Mussel & Vitamin E
Big dogs build more joint, over a longer runway, under more weight — and MoveGuard Growth is the formula that takes all three seriously. Nine transparently dosed actives — NZ Green-Lipped Mussel, Antarctic Krill Oil, glucosamine, chondroitin, MSM, hyaluronic acid, manganese, and vitamins C and E — support normal joint development and everyday mobility across the full 8-30 month big-dog window, dosed by expected adult weight so a future 140-pounder gets support scaled to the frame it's assembling. Owners of Danes, Mastiffs, Newfoundlands, Leonbergers and Shepherds rate it 4.9 stars. About $1 a day on Subscribe & Save, vet-reviewed, 60-day money-back guarantee. Raising a big one is a bigger project — support it like one.
The building timeline
The big-dog building timeline: 8 to 30 months.
Here's what's actually happening under all that fur — and how daily support lines up with each phase. From 8 to 12 months, rapid lengthening is still underway: growth plates are open, bones are extending, cartilage surfaces are being laid down, and weight is climbing fast. Large breeds approach most of their adult height; giants are just hitting their stride.
That makes 8 months the ideal starting age. Daily structural building blocks — glucosamine, chondroitin, manganese — supply the active construction, while GLM and krill omega-3s support comfortable everyday movement. From there, the job changes phase by phase as the frame fills out.
- 12-18 months The heaviest-load phaseLarge breeds reach roughly full height and their plates begin hardening; giants keep lengthening — near-adult weight riding on joints still maturing underneath. Hyaluronic acid supports joint-fluid cushioning while chondroitin helps cartilage stay spongy and resilient.
- 18-24 months Giants still under constructionGiant-breed growth plates close through this stretch while muscle and bulk keep building onto the frame. MSM keeps feeding connective-tissue formation as tendons and ligaments finish developing.
- 24-30 months The giants' final stretchThe last of the skeletal maturing wraps up and the adult frame settles in — the tail of the window that only the very biggest dogs use.
When the build is complete, graduate: MoveGuard Adult continues the same transparent, GLM-anchored philosophy for the grown dog's maintenance years.
Find your tier
The Big-Dog Size Check
Is your pup a large or a giant — and where are they on the big-dog building timeline? Three quick questions. This is a general sizing and readiness guide, not a medical assessment, and it can't detect or diagnose anything. (MoveGuard Growth is formulated for dogs maturing to 50 lb and up.)
You're in the big-dog building window
Your pup is squarely in the phase this formula was built for: a big frame actively laying down cartilage and connective tissue, with growth plates open on a big-dog schedule. Dose by expected adult weight — 2 chews a day for dogs maturing to 50-80 lb, 3 a day for 80-100+ lb — so the support scales to the frame actually being built. A 90-chew jar runs about 30-45 days depending on tier, it works out to about $1 a day on Subscribe & Save, it's vet-reviewed, and it's backed by a 60-day money-back guarantee.

Almost time — the window opens at 8 months
You're ahead of schedule, which is the best place to be. 8 months is the ideal age to start MoveGuard Growth for most large and giant breeds — if your pup's growth spurt comes early, it's fine to begin a little sooner. Bookmark this page, note their 8-month date, and you'll be supporting the build from the very start of the window.

Build complete — time for the maintenance formula
Your big dog has finished the building years, so the Growth formula's development-stage dosing is no longer the right match. MoveGuard Adult carries the same philosophy forward — transparent, properly dosed actives including NZ Green-Lipped Mussel — tuned to support ongoing mobility and everyday comfort in grown dogs. Same vet-reviewed approach, same 60-day guarantee.

“Joint support works best before the stiffness — during the growth window, not after. Big and giant breeds are still building those joints out past two years. MoveGuard Growth supports those growing joints while the frame is still forming — with real doses of glucosamine, green-lipped mussel and krill oil, printed right on the jar.”

Honest questions, honest answers
What big-dog parents ask before they start.
My puppy already weighs 90 lb at 12 months — is it too late to start?
No. Giant frames keep building toward 24-30 months, with growth plates open into the 18-24 month range and sometimes beyond. If your dog is inside the 8-30 month window, the construction is still underway — and daily building blocks still have a job to do.
Why does a big dog need a different formula than a small dog?
Because size rewrites the project: a big dog builds more joint (a 100+ lb frame carries roughly ten times the skeleton of a toy breed), over a longer window (up to 30 months vs 6-8 for the smallest dogs), under more weight arriving before the joints are finished. MoveGuard Growth is formulated and dosed for exactly that combination.
How many chews does my dog need, and how long does a jar last?
Dose by EXPECTED adult weight: 2 soft chews a day for dogs maturing to 50-80 lb, 3 a day for 80-100+ lb. Each jar holds 90 chews — about 45 days for the large tier, about 30 for the giant tier.
When does my dog graduate to MoveGuard Adult?
When the build is complete — around 24 months for most large breeds and closer to 30 for giants. MoveGuard Adult continues the same transparent, GLM-anchored approach, tuned for a grown dog's maintenance years.
My dog will be under 50 lb — is this for us?
MoveGuard Growth is formulated and dosed specifically for dogs maturing to 50 lb and up, because big frames build longer and carry more. For a smaller pup, ask your veterinarian what stage-appropriate support makes sense — smaller breeds finish growing much earlier and their needs differ.
Is this a medical product?
No. MoveGuard Growth is a daily supplement that supports normal joint development in growing large and giant breeds. It is vet-reviewed, made in the USA in a GMP-certified, NSF facility, about $1/day on Subscribe & Save with a 60-day money-back guarantee — and it is not intended to diagnose, treat, cure, or prevent any disease. Consult your veterinarian about your puppy's individual needs.

The big build is happening now
Raising a big one is a bigger project. Support it like one.
More joint to build, a longer runway to build it on, and adult-sized weight arriving early — that's the project you signed up for when you fell for the giant paws. The good news: it runs on a schedule you already know, and the support is one small daily habit dosed to the dog he's becoming. Give the big frame its building blocks while the building is happening — starting today.
