You picked up the PetLab Co bag because the ad looked right and the ingredients sounded right. Now you are reading the back of it, wondering what a joint chew is supposed to contain.
Quick answer: Pick OcuLabs Hip + Joint Support Chews. The two share a backbone of glucosamine, green-lipped mussel, wild Alaskan salmon oil and turmeric, and OcuLabs adds four joint ingredients PetLab Co Joint Care does not list: chondroitin sulfate, MSM, hyaluronic acid and Boswellia. One jar lasts 45 days at two a day, against 30 days for a bag, and your first order is covered for 90 days.
PetLab Co Joint Care vs OcuLabs Hip + Joint: side by side
The short version: both start from glucosamine, green-lipped mussel, salmon oil and turmeric. Only OcuLabs adds chondroitin, MSM, hyaluronic acid and Boswellia, in a jar that lasts 45 days.

What OcuLabs adds that PetLab Co does not
- Chondroitin sulfate. The partner glucosamine is almost always paired with, because the combination tests better than either alone. It draws water into cartilage and inhibits the enzymes that break it down.
- MSM. An organic sulfur compound. Cartilage and connective tissue need sulfur, and MSM has its own evidence base for joint comfort.
- Hyaluronic acid. The main component of joint fluid, the stuff that keeps a joint moving smoothly.
- Boswellia. Frankincense extract, which joins turmeric in supporting a normal inflammatory response.
Those four complete the standard joint checklist: cartilage building blocks, sulfur, omega-3s, comfort botanicals and joint fluid, in one chicken chew that is third-party tested and sold only at ocupetlabs.com. For what the green-lipped mussel does, read green-lipped mussel for dogs.
Which dogs is OcuLabs right for?
- A senior with stiffness who should be getting chondroitin and MSM, not only glucosamine.
- An owner who wants the full joint checklist without a second product.
- Anyone who would rather reorder every 45 days than every 30.
- An owner who wants the trial window covered: the guarantee runs 90 days from delivery.
How to read any joint chew label in two minutes
- Find the omega-3s. Green-lipped mussel, salmon oil or fish oil. If none is listed, you will be buying a fish oil as well.
- Check the cartilage trio. Glucosamine, chondroitin and MSM. Glucosamine alone is the thinnest version.
- Look for the comfort and fluid layer. Turmeric, Boswellia and hyaluronic acid.
- Work out the days per pack. Chews in the pack divided by chews a day, including any loading phase.
- Read the allergy lines. Glucosamine and mussel usually come from shellfish, and the flavour is a protein too.
Whichever you choose, give it daily with food and judge it over 60 to 90 days on the same moments: rising after rest, the stairs, the car, the length of the walk. Limping or sudden pain need a vet first; see signs of arthritis in senior dogs.
Give his joints the full checklist, every morning
OcuLabs Hip + Joint Support Chews take the mussel-and-salmon idea and finish the job, in a chicken chew he will wait by the bowl for.
- Easier first steps after a nap. Glucosamine and chondroitin support healthy cartilage.
- More comfort on the walk. Green-lipped mussel and wild Alaskan salmon oil bring the omega-3s EPA and DHA.
- Less hesitation at the stairs and the car. Turmeric and Boswellia support a normal inflammatory response.
- Smoother movement onto the couch. Hyaluronic acid supports joint fluid, and MSM supplies sulfur for connective tissue.
Your first order is covered for 90 days from delivery, whatever the pack size. If you do not see the difference, email support@ocupetlabs.com for a full refund of the product price, opened or empty jars included.

Frequently asked questions
Is PetLab Co Joint Care or OcuLabs better for a senior dog?
OcuLabs Hip + Joint Support Chews. It has everything the two share (glucosamine, green-lipped mussel, wild Alaskan salmon oil and turmeric) plus four joint ingredients PetLab Co does not list: chondroitin sulfate, MSM, hyaluronic acid and Boswellia. A jar also lasts 45 days at two a day, against a 30-day bag.
What is in PetLab Co Joint Care Chews?
Four of the same actives as OcuLabs (glucosamine, green-lipped mussel, wild Alaskan salmon oil and turmeric), with none of the chondroitin, MSM, hyaluronic acid or Boswellia that OcuLabs adds. It comes in 30-chew bags, a 30-day supply.
What does OcuLabs add that PetLab Co does not?
Chondroitin sulfate and MSM for cartilage and connective tissue, hyaluronic acid for joint fluid, and frankincense (Boswellia) extract for a normal inflammatory response. Those sit on top of the glucosamine, green-lipped mussel, salmon oil and turmeric the two share.
Which lasts longer, a bag of PetLab Co or a jar of OcuLabs?
The OcuLabs jar. It holds 90 chews, a 45-day supply at two a day. A PetLab Co Joint Care bag holds 30 chews, a 30-day supply.
Can I give PetLab Co Joint Care and OcuLabs together?
There is no need. OcuLabs already contains the glucosamine, green-lipped mussel, salmon oil and turmeric in PetLab Co, so stacking them doubles up. Give OcuLabs on its own daily for 60 to 90 days and judge it on rising, stairs and walk length.
