Why it matters
Your dog is aging 7 times faster than you.
Every year you share with your dog is seven years of biological change happening inside them. By the time most dog owners notice the signs — the stiff mornings, the shorter walks, the grey spreading across the muzzle — the underlying cellular decline has been underway for years. Understanding what aging actually is at a biological level is the first step to doing something meaningful about it.

The biology of canine aging
What is actually happening inside your dog.
Aging is not a mystery. It is a biological process driven by compounding cellular decline across multiple systems. Here is what is happening inside every aging dog — and why it accelerates without support.
1
Joint cartilage breakdown
Cartilage — the cushioning tissue between joints — breaks down faster than the body can rebuild it. The enzymes responsible for this breakdown increase with age. Without targeted support every step your dog takes accelerates the damage. This is why stiffness after rest is one of the first visible signs of aging in dogs.
2
Cellular energy decline
Every cell in your dog's body requires NAD+ to function. It powers DNA repair, energy production, and cellular maintenance. By middle age NAD+ levels have dropped significantly. When cells cannot maintain themselves everything slows down — mobility, cognition, immunity, energy. This is why aging dogs seem to decline across multiple systems simultaneously.
3
Gut microbiome disruption
The canine gut microbiome shifts significantly with age. Beneficial bacteria decline. Inflammatory strains increase. The gut-brain axis — which influences mood, cognition, and immune response — becomes less stable. This is why many aging dogs become more anxious, less engaged, and more prone to digestive issues simultaneously.
4
Systemic inflammation
Chronic low-grade inflammation is now understood to be one of the primary drivers of aging across all mammals. It damages healthy tissue, accelerates joint decline, impairs cognitive function, and weakens immune response. Omega-3 fatty acids and targeted antioxidants are the most evidence-backed tools for reducing it.
5
Cognitive and neurological changes
DHA — the Omega-3 fatty acid found primarily in fish oil — is the primary structural fat in brain tissue. As dogs age and DHA levels decline cognitive sharpness follows. Dogs become less responsive, less engaged, and in some cases develop Canine Cognitive Dysfunction. Early supplementation is the most effective preventative measure available.
The formula
Five ingredients. Five systems. One daily chew.
Every active ingredient in Give More Years is chosen because the research specifically on dogs is solid — not because it works in humans and might translate. Here is exactly what is in every chew and why it is there.
Glucosamine HCl and Chondroitin Sulfate550mg
The most clinically studied combination in canine joint health. Glucosamine is the building block of cartilage — it provides the raw material the body needs to rebuild joint tissue. Chondroitin works by inhibiting the enzymes that break cartilage down. Together they address joint decline from two directions simultaneously. At 550mg this is a therapeutic dose — most budget supplements include 100 to 200mg which falls below the threshold for meaningful effect.
Premium Fish Oil — Omega-3 EPA and DHA200mg
EPA reduces systemic inflammation — the chronic low-grade inflammatory state that accelerates aging across every system in the body. DHA is the primary structural fat in brain tissue and is directly associated with cognitive function and sharpness in aging dogs. Together they are the most evidence-backed anti-inflammatory intervention available without a prescription.
Bacillus subtilis — Spore-forming Probiotic1 Billion CFU
Most probiotic supplements use standard strains that are destroyed by stomach acid before they reach the gut. Bacillus subtilis is a spore-forming strain — it survives digestion and actively colonises the intestinal tract. At 1 Billion CFU per chew it delivers meaningful gut microbiome support. The gut-brain axis in dogs means gut health directly influences cognitive engagement, immune response, and even mood.
B-Complex and Vitamin E — 10 active compounds25mg
Ten compounds in one blend: B1, B2, B3, B5, B6, B12, Biotin, Folic Acid, Manganese, and D-Alpha Tocopherol. B vitamins power every energy-producing reaction in the body — from nerve signalling to muscle function. Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. Biotin supports skin, coat, and nail health.
Vitamin C — Ascorbic AcidImmune support
Dogs synthesise some Vitamin C naturally but aging, stress, and illness deplete it rapidly. Supplemented Vitamin C supports immune resilience, collagen production for healthy joints and skin, and the antioxidant pathways that neutralise the free radicals that accelerate cellular aging.

Veterinary perspective
What veterinary advisors say about this.
Give More Years is formulated in consultation with Canadian veterinary advisors. Here is the perspective on joint health, gut support, and anti-aging supplementation in aging dogs.
"Joint health supplementation with Glucosamine and Chondroitin is one of the most evidence-backed interventions we have for aging dogs. The key is dose — at therapeutic levels the research consistently shows meaningful improvements in mobility and comfort. The addition of Omega-3 EPA and DHA addresses the inflammatory component that joint supplements alone do not target. This is a comprehensive approach."
Veterinary advisor perspective — Give More Years formulation team
When to start anti-aging support
Most veterinarians recommend starting joint and cellular support from age 5 in medium to large breeds and from age 7 in small breeds. Large and giant breeds — Labradors, German Shepherds, Bernese Mountain Dogs — age faster and benefit from earlier intervention. The goal is to support healthy tissue before decline accelerates, not react to it after the damage is done.
Safety and dosing
Give More Years is formulated for dogs of all breeds and sizes with weight-based dosing. All active ingredients are within established safe ranges for canine supplementation. The formula is produced in a GMP-certified facility. If your dog has existing health conditions or is on prescription medication we recommend consulting your veterinarian before starting any new supplement.
Common questions
What Canadian dog parents ask most.
How long before I see a difference in my dog?
Most Canadian dog parents report noticeable changes in energy and engagement within 3 to 6 weeks. Mobility improvements typically emerge by weeks 4 to 8 as joint support compounds. Cognitive improvements can take 8 to 12 weeks. Results build month over month — the longer your dog is on Give More Years the more pronounced the benefit.
Is this safe alongside my dog's current medication?
Give More Years is formulated from ingredients with well-established safety profiles in dogs. Glucosamine and Chondroitin are commonly recommended alongside prescription joint medications. Omega-3 fish oil has a strong safety record. If your dog is on blood thinners or has a diagnosed condition we recommend checking with your vet before starting.
Why does my dog need a supplement — isn't their food enough?
Standard commercial dog food meets baseline nutritional requirements but is not formulated to address the accelerated cellular and joint decline of aging specifically. The therapeutic doses of Glucosamine, Chondroitin, and Omega-3 required to have meaningful effect on aging joints and inflammation are not present in standard kibble at any price point. Supplementation is how you bridge that gap.
My dog has a shellfish allergy — can they still take this?
The Glucosamine in Give More Years is derived from shellfish. If your dog has a confirmed shellfish allergy please consult your veterinarian before starting. All other actives are plant, animal, or fermentation-derived with no common allergen concerns.
What age should my dog start Give More Years?
We recommend starting from age 5 for medium to large breeds and age 7 for small breeds. You do not need to wait until your dog shows visible signs of slowing down — the earlier you support cellular health, joint tissue, and gut function the more there is to protect. Anti-aging support works best as prevention, not reaction.
Does this ship across all of Canada including Quebec?
Yes — free shipping to every province and territory in Canada. Orders are processed the next business day. Quebec customers: our packaging and inserts include French as required. Most Canadian orders arrive within 3 to 7 business days depending on your province.
