Dr. Ferg's Mobility Soft Chews for Dogs Test

The Joint & Hip Soft Chew Your Dog Actually Deserves

Formulated by a vet. Built around the science. Made in New Zealand with human-grade ingredients — because your dog's joints deserve the same standard we hold ourselves to.

Every ingredient has a reason.

We don't do proprietary blends. Every active ingredient is named, sourced, and there for a specific reason we can explain at the kitchen table.

Type II Collagen — 30mg (NZ grass-fed beef cartilage · CollaMex®) The structural protein of joint cartilage. Our Type II Collagen comes from New Zealand free-range, grass-fed bovine cartilage — the same collagen type found in your dog's joints. Research shows meaningful joint support at doses consistent with what your dog receives in every chew. This is the ingredient that does the real work.

Greenshell™ Mussel — 32mg (New Zealand defatted powder) New Zealand's most celebrated marine ingredient. A natural source of omega-3 fatty acids (including the rare ETA), glycosaminoglycans, and chondroitin sulphate — all in one whole-food ingredient. Nowhere else on earth produces it quite like the Greenshell waters of New Zealand.

Glycosaminoglycans — 16mg (NZ beef cartilage) The natural building blocks of healthy cartilage and synovial fluid. GAGs help support the structural integrity of your dog's joints and contribute to the cushioning that keeps movement comfortable.

Calcium — 30mg (MCHCal® bone powder · NZ sourced) Not just any calcium. MCHCal® is a microcrystalline hydroxyapatite calcium — the same crystalline form found in healthy bone — and it includes bioactive growth factors and bone proteins alongside the mineral itself.

Type I Collagen — 24mg (NZ grass-fed bone powder) The collagen of bones and tendons. Works alongside Type II Collagen to support the connective tissue framework that keeps joints properly supported and aligned.

We lead with what actually works.

Most joint supplements put glucosamine front and center. We lead with Type II Collagen — because that's what the clinical evidence points to. Research shows meaningful joint support at doses consistent with what your dog receives in every chew of Dr. Ferg's.

The Greenshell™ Mussel is there because it's one of the most complete natural joint-support ingredients on earth. As a whole-food source of omega-3s, chondroitin, and GAGs alongside a strong collagen base, it earns its place in this formula.

We use "supports" language throughout because that's honest. These chews support joint health. They don't treat disease. If your dog has a serious mobility condition, please talk to your vet — that's what we'd tell you if you asked us in person.

How to use

Dog Weight	Daily Dose	Pack Duration
Under 50 lbs	1 chew per day	60-day supply
50 lbs and over	2 chews per day	30-day supply

For best results, allow 4–6 weeks of consistent daily use. Joint support supplements work gradually — the dogs that see the biggest difference are the ones whose owners don't miss a day.

Why New Zealand?

New Zealand's pasture farming system, clean water, and stringent biosecurity standards consistently produce animal-derived ingredients of exceptional purity. Our ingredient partner has been supplying human-grade nutraceutical ingredients since 1987 — they make ingredients for human health products, and we hold our pet ingredients to the same standard. Every active ingredient in Dr. Ferg's is traceable back to the farm it came from. That traceability matters to us.

What dog owners are telling us

"Daisy is a 9-year-old Cavalier and she's been reluctant to jump on the couch for over a year. Six weeks on these chews and she's jumping again. I nearly cried the first time I saw it." — Sarah K., verified buyer

"I work in health care, I read labels. Dr. Ferg's is the first pet supplement where I actually trust what's on the label — the sourcing, the honest dosing guide that doesn't overclaim. More of this please." — Michael T., verified buyer

"My vet recommended I try a collagen-based joint supplement before we talked about pain meds. Found Dr. Ferg's and figured a vet-made product was a good place to start. Eight weeks later, we haven't had to have that conversation." — Amanda L., verified buyer

Common questions

How quickly will I see results? Joint supplements are a long game. The collagen and supporting ingredients in Dr. Ferg's work by supporting your dog's natural cartilage maintenance over time — not by masking pain acutely. Most owners notice meaningful changes in willingness to move, ease of getting up, and general comfort between 4 and 6 weeks of daily use. Consistency is everything.

Why is Type II Collagen the lead ingredient? Most dog joint supplements lead with glucosamine. We've chosen to lead with Type II Collagen because the clinical evidence for it is genuinely strong at the dose your dog receives in every chew. It's the structural protein of joint cartilage itself — the same type found in your dog's joints.

Are these safe for long-term daily use? Yes. The ingredients — Type II Collagen, Greenshell™ Mussel, bone-derived calcium, and glycosaminoglycans — are all natural, food-grade compounds with excellent safety profiles. No synthetic additives, no artificial preservatives, nothing that accumulates harmfully with daily use.

Can I use these alongside my dog's current medication? For most dogs, yes. Our ingredients are natural food-grade compounds with no known interactions with common veterinary medications. If your dog is on prescription pain management or has a diagnosed joint condition, please check with your vet first. That's genuinely what we'd tell you in person.

What if my dog doesn't like the taste? Dr. Ferg's chews are soft with a natural, real beef-forward flavour. The vast majority of dogs take them as a treat with no encouragement. If your dog is genuinely fussy, try crumbling into food. If after two weeks they still won't take them, we'll refund you — no hoops.
