The bottom line
PetLab Co's Joint Care Chews earn our top supplement grade because the label does what pet supplement labels are supposed to do: name every active ingredient with amounts, carry the NASC Quality Seal, and describe benefits in honest structure/function language — "supports hip and joint health," not "cures arthritis." If you're buying a joint supplement for a dog that's slowing down, this is the transparency bar the rest of the aisle should clear.

What it is
PetLab Co's Joint Care Chews are a daily soft-chew supplement formulated to support hip and joint health and help maintain joint mobility in dogs. The formula centers on the standard joint-support ingredients veterinarians actually recognize — glucosamine HCl, green-lipped mussel (MMP-50), omega-3s from anchovy oil, calcium fructoborate, and Curcugen® (a turmeric-derived ingredient) — in a pork-flavored chew most dogs take willingly.
PetLab Co states its formulas are developed with veterinarians and pet-health experts, and the brand is an NASC member — meaning its facilities are subject to the National Animal Supplement Council's audit and adverse-event reporting program. For the full explainer on what that seal does and doesn't certify, see our guide to what the NASC seal actually means.

Ingredient disclosure: Strong
This is where PetLab Co separates from most of the joint-support aisle. The label names each active ingredient — glucosamine HCl (from shellfish), MMP-50 green-lipped mussel, omega-3 fatty acids (EPA and DHA from anchovy oil), calcium fructoborate, and Curcugen® — with per-chew amounts stated. No "proprietary joint blend," no mystery powders.
The inactive ingredients are equally plain: apple cider vinegar, coconut glycerin, coconut oil, dried brewer's yeast, hickory smoke flavor, lecithin, maltodextrin, rosemary extract, salmon hydrolysate, sunflower oil, sweet potato. Nothing hidden, nothing you need a chemistry degree to parse. Learn to audit any label this way in our guide to reading a pet supplement label.
Feeding directions
The label's daily feeding guide is refreshingly specific: under 25 lbs — 1 soft chew; 25–75 lbs — 2 soft chews; over 75 lbs — 3 soft chews. Weight-banded dosing is another small honesty signal — it acknowledges that a Chihuahua and a Great Dane don't need the same serving.
Claim language: honest
PetLab Co describes these chews as supporting hip and joint health, helping maintain joint mobility, and supporting healthy joints and connective tissue — textbook structure/function language. You won't find "treats arthritis," "rebuilds cartilage," or "eliminates stiffness" on the compliant label copy. That's exactly the line: a supplement supports normal structure and function; it doesn't diagnose, treat, or cure disease.
What to keep in perspective
- Supplements are slow. Joint-support ingredients work over weeks of consistent daily use. A chew your dog won't eat every day is worthless no matter how good the formula — palatability is genuinely part of the product.
- This is support, not treatment. If your dog is limping, in visible pain, or has a diagnosed joint condition, that's a vet visit — not a shopping trip.
- Subscription economics. PetLab Co sells primarily by subscription, and it's easy to end up stacking multiple products (joint, probiotic, dental) into a meaningful monthly bill. Audit your stack with your vet; overlap is common.
- Shellfish source. The glucosamine is shellfish-derived — relevant if your dog has a known shellfish sensitivity. Check with your vet.
Pros and cons
Pros
- NASC member with the Quality Seal — the category's best third-party signal
- Every active ingredient named with per-chew amounts; no proprietary blends
- Weight-banded feeding directions
- Honest structure/function claim language throughout
- Soft-chew format most dogs take willingly
Cons
- Subscription-first sales model — watch for product stacking across their line
- Premium positioning; pricing varies, so compare cost per daily serving
- Glucosamine is shellfish-derived (flag for sensitive dogs)
- Like all joint supplements: support over weeks, not an overnight fix
Who should choose it
A great fit if: your dog is getting slower on stairs or long walks, you want a joint supplement with an auditable label and NASC certification, and your vet is on board. Talk to your vet first if: your dog has a diagnosed joint condition, is on medication, or you're already giving other supplements — stacking overlaps are the most common supplement mistake we see.
Frequently asked questions
Does PetLab Co Joint Care actually work?
The honest answer: the formula contains the joint-support ingredients most commonly recommended in veterinary practice, in stated amounts, from an NASC-certified maker. Supplements support normal joint structure and function over weeks of consistent use — they're not treatments for diagnosed disease. Individual results vary; discuss expectations with your vet.
Is PetLab Co NASC certified?
Yes — PetLab Co is a member of the National Animal Supplement Council, and its products carry the NASC Quality Seal, which indicates the company submits to facility audits and maintains adverse-event reporting. Here's what that seal means.
How long before I see a difference?
Joint-support supplements are typically given daily for several weeks before owners report noticing changes in mobility and comfort — and "noticing" is subjective. Keep a simple log (stairs, walk length, willingness to play) so you're judging change, not hope. And if your dog is in pain, see your vet first.
Can I give these with other supplements?
Ask your vet. Overlap between joint, mobility, and "senior" formulas is extremely common, and more isn't better. Bring the labels to your appointment.
