Which One Does Your Dog Need Right Now?
If your large or giant breed dog is between 8 and 30 months old, choose MoveGuard Growth — it is built for the developmental phase when joints are still being constructed. If your dog is a grown adult whose growth plates have closed, choose MoveGuard Adult — it is built for daily maintenance of joints that are already fully formed. They are not interchangeable. Same brand, entirely different biological targets, different active ingredients, different dosing logic. The single decision point is age and growth stage — not breed, not weight, not whether your dog currently has joint problems.

Shop MoveGuard Growth →MoveGuard Adult
24+ months · 8 actives · Eggshell Membrane 150mg + NZ Green-Lipped Mussel 300mg · Flat 2 chews/day for all 25–75 lb · 60 chews
Shop MoveGuard Adult →- MoveGuard Growth and MoveGuard Adult are purpose-built for different biological phases — they share a brand name and a commitment to label transparency, but they are not versions of the same supplement
- MoveGuard Growth leads with Antarctic Krill Oil (150mg) and NZ Green-Lipped Mussel (250mg) plus growth-phase co-factors — vitamin C, manganese, lower-dose hyaluronic acid — to support joints being built
- MoveGuard Adult leads with Eggshell Membrane (150mg) and higher-dose NZ Green-Lipped Mussel (300mg) plus substantially higher glucosamine (1000mg), chondroitin (800mg), and MSM (800mg) — to protect and maintain joints already formed
- The transition from Growth to Adult should happen after confirmed growth plate closure — for large breeds around 18–24 months, for giant breeds 24–30 months
- MoveGuard Growth doses by expected adult weight; MoveGuard Adult is a flat 2-chew daily serving for every dog 25–75 lb regardless of weight
- Both formulas disclose every active ingredient dose individually — no proprietary blends in either product
- Both are made in a GMP/NSF-certified facility in the USA and vet-reviewed
The Core Difference: Build vs Protect
The clearest way to understand MoveGuard Growth vs MoveGuard Adult is through the biological job each one is doing. These are not a "starter" and "premium" version of the same supplement. They are formulas designed around two distinct phases of joint biology — and the priorities of those phases are genuinely different.
MoveGuard Growth — The Construction Phase
- Growth plates are open — the skeleton is not yet complete
- Cartilage is actively being synthesised at high rate
- Collagen demand is elevated — the body needs co-factors for synthesis
- Synovial fluid is forming in joint spaces still under development
- Rapid weight gain is loading joints that are not yet fully mineralised
- The window is defined and finite — it closes and cannot be reopened
- Priority: supply the building blocks and anti-inflammatory support that construction demands
MoveGuard Adult — The Maintenance Phase
- Growth plates are closed — the skeleton is structurally complete
- Cartilage wears gradually under years of daily mechanical loading
- The joint matrix (collagen, elastin, glycosaminoglycans) needs ongoing nutritional support
- Inflammatory regulation remains important — daily activity generates ongoing low-level joint stress
- Synovial fluid quality supports comfortable movement but does not need the same development support
- The window is permanent — maintenance continues for the rest of the dog's life
- Priority: protect existing cartilage, support the joint matrix, regulate the inflammatory response daily
This is why giving an adult dog MoveGuard Growth, or a growing puppy MoveGuard Adult, is not merely suboptimal — it is providing the wrong formula for the wrong biological context. A puppy on an adult formula receives no growth-phase co-factors and lower doses of the structural actives it needs most during rapid development. An adult dog on a growth formula receives krill oil and growth-phase co-factors it no longer needs at the rates present in Growth, while missing the higher glucosamine doses and Eggshell Membrane that an adult maintenance formula should lead with.

Ingredient Deep Dive: Every Active, Both Formulas
Here is a complete ingredient-by-ingredient breakdown of both formulas — what each active does, why it is in one formula but not the other, and where the doses differ meaningfully.
| Ingredient | MoveGuard Growth | MoveGuard Adult | Why the difference |
|---|---|---|---|
| NZ Green-Lipped Mussel | 250mg | 300mg | Present in both but at a higher dose in Adult — the adult formula relies more heavily on GLM's ETA omega-3 since krill oil is not included. GLM also provides natural glycosaminoglycans and chondroitin in whole-food form, making it a dual-function ingredient in the adult formula. |
| Eggshell Membrane | Not present | 150mg | Eggshell Membrane — a natural source of collagen, elastin, and glycosaminoglycans — is specifically clinically studied for joint maintenance and comfort in adult dogs. Its primary application is protecting and supporting the existing joint matrix in adults. In the Growth formula, collagen support is handled by vitamin C and manganese as synthesis co-factors rather than a whole-food matrix ingredient. They are addressing the same biological system (collagen) from different angles appropriate to each life stage. |
| Glucosamine HCl | 400mg | 1000mg | The Growth formula doses glucosamine appropriately for the developmental phase — when the body is synthesising cartilage from precursor materials, moderate glucosamine supplementation is the correct approach. The Adult formula significantly increases the dose to 1000mg because in an adult dog, the priority shifts to replenishing the glucosamine that daily wear consumes from established cartilage. This is not simply a "bigger dose for a bigger dog" — it reflects a fundamentally different metabolic goal. |
| Chondroitin Sulfate | 300mg | 800mg | Same rationale as glucosamine — the adult formula substantially increases chondroitin because the maintenance target (protecting existing cartilage from enzymatic breakdown) requires a higher sustained dose than the developmental support target. Chondroitin at 800mg in an adult formula is the maintenance-tier dose; 300mg in the growth formula reflects development-tier supplementation. |
| MSM | 250mg | 800mg | MSM's role as a bioavailable sulfur source and antioxidant support ingredient is relevant in both phases, but the dose is substantially higher in the adult formula. Adult dogs generating daily low-grade inflammatory load from regular activity benefit from higher MSM doses for ongoing antioxidant balance. The growth formula uses a moderate dose appropriate for a puppy's developing system. |
| Antarctic Krill Oil | 150mg | Not present | Krill oil is a Growth-specific addition providing phospholipid-form EPA and DHA — a highly bioavailable marine omega-3 source that complements GLM's ETA pathway during the developmental window. In the Adult formula, the increased GLM dose at 300mg handles the primary marine omega-3 requirement. The krill oil's presence in Growth reflects the dual omega-3 strategy appropriate for developing joints under higher nutritional demand. |
| Hyaluronic Acid | 15mg | 25mg | Hyaluronic acid supports synovial fluid quality in both formulas — but the adult formula uses a higher dose. In developing joints, HA supplementation is a supporting role alongside the primary structural actives. In adult joints, where synovial fluid quality is a primary daily comfort factor, a higher HA dose is the appropriate maintenance approach. |
| Vitamin C | 50mg | 75mg | Vitamin C's role as a collagen synthesis co-factor is relevant throughout life, but the Growth formula includes it specifically because collagen synthesis demand is elevated during rapid tissue growth. The adult dose at 75mg maintains antioxidant and collagen-support functions without the growth-phase elevation rationale. |
| Vitamin E | 25 IU | 35 IU | Antioxidant support across both formulas, with a slightly higher adult dose reflecting adult dogs' longer daily antioxidant exposure. |
| Manganese | 2mg | Via Eggshell Membrane matrix | Manganese is a co-factor for glycosaminoglycan and connective tissue formation — particularly relevant during the construction phase when these structures are being synthesised. In the Adult formula, the Eggshell Membrane matrix provides structural support through its natural complex of glycosaminoglycans, reducing the need for a separate manganese addition. |
One of the most counterintuitive findings in this comparison: MoveGuard Adult contains more NZ Green-Lipped Mussel (300mg) than MoveGuard Growth (250mg). This is intentional. In the Growth formula, the marine omega-3 workload is shared between GLM and krill oil. In the Adult formula, krill oil is absent — so GLM carries the full marine omega-3 responsibility alongside its structural glycosaminoglycan role. The higher adult GLM dose compensates for the absence of krill oil while delivering more of GLM's specific ETA omega-3 benefit to a dog whose joints need daily inflammatory management under ongoing activity.

Take the Quiz →Why the Formulas Are So Different
If the two formulas were simply different dose levels of the same ingredients, the comparison would be straightforward. The more interesting question is why the ingredient lists themselves are different — why krill oil appears in Growth but not Adult, why eggshell membrane appears in Adult but not Growth, and why the glucosamine dose nearly triples between the two.
The Growth philosophy: supply what the body is demanding during construction
A large breed puppy between 8 and 30 months is synthesising cartilage, mineralising growth plates, building synovial joint spaces, and forming the connective tissue that holds the skeletal system together. Every one of these processes has specific nutritional demands. Vitamin C is required for collagen synthesis — and collagen synthesis demand is substantially elevated during rapid growth. Manganese is a co-factor for glycosaminoglycan formation. Hyaluronic acid supports the synovial fluid being produced in joints whose spaces are still developing. Antarctic Krill Oil provides phospholipid-form EPA and DHA — the most bioavailable marine omega-3 form for tissue that is actively incorporating fatty acids during development.
MoveGuard Growth does not provide these ingredients because they are generally beneficial — it provides them because each one addresses a specific biological demand that is uniquely elevated during the growth window.
The Adult philosophy: protect what has been built against daily attrition
An adult dog's joints are structurally complete. The priority shifts from synthesis to maintenance — protecting cartilage from the enzymatic breakdown and mechanical wear that daily activity generates, supporting the inflammatory response that accompanies normal activity, and maintaining the synovial fluid quality that keeps movement comfortable. Eggshell Membrane is the adult formula's hero active because it is a clinically studied, whole-food source of the exact components of the joint matrix (collagen, elastin, glycosaminoglycans) that undergo daily attrition. The substantially higher doses of glucosamine, chondroitin, and MSM in the adult formula reflect the maintenance-tier dosing strategy — providing a sustained daily supply of these compounds to replace what daily wear removes.
Dosing: How Each Formula Works
MoveGuard Growth — weight-based dosing by expected adult weight
MoveGuard Growth doses by expected adult weight — not current puppy weight. This is deliberate: an 8-month Labrador that currently weighs 50 lbs will be a 70 lb adult. The dose is set for where the dog is going, not where it is right now, because the supplement is supporting joint architecture that will carry that adult weight for the next decade.
- 50–80 lb expected adult weight → 2 chews per day → one 90-chew jar lasts approximately 45 days
- 80–100+ lb expected adult weight → 3 chews per day → one 90-chew jar lasts approximately 30 days
MoveGuard Adult — flat serving for all dogs 25–75 lb
MoveGuard Adult uses a flat serving of 2 chews per day for every medium and large adult dog in the 25–75 lb range. No weight chart required. One 60-chew jar lasts approximately 30 days for every dog in the target range.
Adult on Growth: The dog receives lower doses of glucosamine (400mg vs the 1000mg adult maintenance dose), lower MSM (250mg vs 800mg), no eggshell membrane, and a phospholipid krill oil supplement calibrated for developmental joint tissue rather than the maintenance support an adult needs. Not harmful — but providing sub-optimal maintenance support while missing the adult formula's primary differentiating ingredient.
Puppy on Adult: The growing puppy receives no krill oil (a key dual omega-3 source for development), no manganese, higher-than-appropriate glucosamine doses calibrated for an adult dog's maintenance needs rather than a puppy's developmental needs, and eggshell membrane — clinically studied for adult joint maintenance, not puppy joint development. Also not harmful, but providing the wrong nutritional support at the wrong biological stage, and missing the growth-phase co-factors that Growth includes specifically for the developmental window.
The Transition: When and How to Switch
The transition from MoveGuard Growth to MoveGuard Adult is the most common question for large breed puppy owners who started on Growth early. It is not a single date — it is a milestone defined by growth plate closure, which varies significantly by breed size.

Decision Tree: Which Formula Is Right?
Breed Guide: Growth Window Lengths by Breed
One of the most important variables in the Growth vs Adult decision is knowing how long your specific breed's growth window actually is. Dogs grow on very different timelines, and the range from smallest large breed to largest giant breed spans more than a year of additional growth window.
Short Growth Window
Boxer, Weimaraner, Rhodesian Ridgeback, Vizsla, Belgian Malinois, German Shorthaired Pointer. Transition to MoveGuard Adult earliest of any large breed — confirm closure at 16–18 months.
Standard Large Breed
Labrador Retriever, Golden Retriever, German Shepherd, Doberman Pinscher. Transition typically at 18–22 months. OFA evaluation at 24 months is standard for these breeds.
Large-Giant Breeds
Rottweiler, Cane Corso, Bullmastiff, Dogue de Bordeaux, Great Dane. Plates typically close 20–24 months. Continue Growth through 22–24 months minimum before transitioning.
Giant Breeds
Bernese Mountain Dog, Newfoundland, Saint Bernard, Mastiff, Leonberger. Some males extend to 28 months. Never transition before radiographic confirmation at this size.
Extreme Giant Breeds
Irish Wolfhound, Great Pyrenees, Anatolian Shepherd, Tibetan Mastiff, Boerboel. The longest growth windows of any breed group. Males especially can extend to 30–36 months. Radiographic confirmation is non-negotiable before transitioning.
MoveGuard Adult From Closure
Regardless of breed or how long the Growth window was — the transition to Adult happens immediately after confirmed growth plate closure. Adult continues for life with no further graduation.
The Bottom Line
Is your dog's skeleton still under construction? MoveGuard Growth. Is it complete? MoveGuard Adult. When in doubt about which side of the line your dog is on, continue Growth and confirm closure with your vet. The cost of staying on Growth slightly past closure is minimal. The cost of switching to Adult before closure — and missing the growth-phase co-factors during the final months of development — is not recoverable.

MoveGuard Growth is formulated for large and giant breed dogs between 8 and 30 months — the growth window when joints are still being built. It contains 9 actives including Antarctic Krill Oil, growth-phase co-factors (vitamin C, manganese), and NZ Green-Lipped Mussel at 250mg. MoveGuard Adult is formulated for adult dogs 25–75 lb whose growth is complete. It contains 8 actives led by Eggshell Membrane (150mg) and a higher GLM dose (300mg), plus substantially higher glucosamine (1000mg), chondroitin (800mg), and MSM (800mg) for adult maintenance. They are not versions of the same supplement — they serve different biological phases.
Transition to MoveGuard Adult after confirmed growth plate closure — not when your dog looks grown. For large breeds (50–80 lb adult), closure typically occurs between 16 and 22 months. For giant breeds (80–100+ lb adult), between 20 and 30 months. The most reliable confirmation is a radiograph; OFA hip evaluation at 24 months doubles as a growth plate check for most breeds. When in doubt, continue Growth and confirm with your vet before switching.
It is not the right formula for the growth window. MoveGuard Adult lacks krill oil, manganese, and growth-phase co-factors that MoveGuard Growth includes specifically for the developmental phase. It also does not contain Eggshell Membrane, which is clinically studied for adult joint maintenance — not puppy development. Adult glucosamine (1000mg) is a maintenance-tier dose rather than the development-tier dose appropriate for a growing puppy. The formulas serve different biological stages — Growth is the correct product for the growth window.
In MoveGuard Growth, the marine omega-3 workload is shared between NZ Green-Lipped Mussel (250mg) and Antarctic Krill Oil (150mg). In MoveGuard Adult, krill oil is not present — so the GLM dose is increased to 300mg to carry the full marine omega-3 responsibility, plus provide more of GLM's ETA omega-3 benefit for a dog generating ongoing daily inflammatory load from activity. The higher GLM dose in Adult compensates for the absence of krill while delivering more of GLM's unique anti-inflammatory pathway to dogs who need daily maintenance.
The glucosamine dose difference (400mg in Growth vs 1000mg in Adult) reflects a fundamentally different goal. During growth, the body is synthesising cartilage from precursor materials — moderate glucosamine supplementation supports that process. In an adult dog, the goal is replacing the glucosamine that daily mechanical wear removes from established cartilage — a higher sustained maintenance dose is the appropriate approach. This is not simply a larger dose for a larger dog; it represents a different metabolic strategy for a different biological phase.
No — MoveGuard Adult is made with oat flour and is not grain-free. MoveGuard Growth is grain-free. If your dog has a known grain sensitivity, confirm the allergen profile with your veterinarian before starting either product. MoveGuard Adult also contains egg (from the Eggshell Membrane ingredient), while MoveGuard Growth does not. Check the current label on each product for the complete allergen notice.
At 20 months, most Labradors are approaching or just past growth plate closure — but not all. The safest approach is to continue MoveGuard Growth until your vet confirms closure, which can be done at a routine check with a hip/elbow X-ray. Staying on Growth a few extra months past closure carries no meaningful downside. Switching to Adult before plates close means missing the final months of growth-phase co-factor support during a still-active developmental period. When your vet confirms closure, switch to MoveGuard Adult immediately and continue for life.
