Quick answer: yes, Equine America has discontinued its Canine & Feline Cortaflex capsules (the sprinkle capsules many owners know as Cortaflex HA capsules). There's no direct capsule replacement: Equine America points owners to its Canine Cortaflex Working Dog Jointcare powder or its Canine Inflamex liquid, and the dog range also includes Cortaflex Senior Jointcare Dog Chews. None of them is the same formula. If you're looking for a new joint supplement anyway, we'd recommend trying MedPaw Hip & Joint Chews instead: a soft chew given like a treat, with all six key joint actives and a 60-day money-back guarantee with nothing to send back.

What happened to the Cortaflex capsules?
Equine America's Canine & Feline Cortaflex Capsules page now says: "Due to the growing popularity of other products in our Pet Jointcare Range we have taken the decision to discontinue our Canine & Feline Capsules." It adds that past buyers "should have received an e-mail notifying you of this news and the alternative options in our Range." The page doesn't give a date.
The capsules weren't among the dog products we saw on cortaflex.co.uk, which showed the Working Dog Jointcare powder, Canine Inflamex Solution, Canine Omega Oil and Senior Jointcare Dog Chews. Other sellers may still have old stock for a while.
It isn't the first change to the dog range. Back in 2020, Trustpilot reviewers complained when the powder was replaced by capsules: "Now nothing is available for dogs except these fancy new very expensive capsules" (Trustpilot reviewer, 1 star, February 2020). For the other complaints and drawbacks, see our Cortaflex dog reviews.
What replaced the Cortaflex capsules?
Here's how the discontinued capsule compares with the products Equine America now sells for dogs, using the amounts on its own product pages.
The discontinued capsule vs the current Cortaflex dog range (per serving, as published)
| Ingredient | Capsules (discontinued), per capsule | Working Dog powder, per 3g | Senior chews, per 2 chews | Inflamex, per 5ml |
|---|---|---|---|---|
| Glucosamine HCl | 348mg | 700mg | 700mg | None |
| Chondroitin sulphate | 47.6mg | 96mg | 100mg | None |
| Hyaluronic acid | 4.4mg | 9mg | 9mg | None |
| Boswellia extract | 20mg | 40mg | 100mg | 20mg |
| Curcumin | 50mg | None | None | 265mg |
| Black pepper extract | 2.5mg | None | None | None |
| UC-II collagen | None | 40mg | 40mg | None |
| Other | Vitamin C 20mg | Vitamin C 40mg, manganese 2mg | Vitamin C 40mg, manganese 2.1mg | Marshmallow 330mg |
Sources: Working Dog powder, Senior chews and Inflamex.
What changed, in short:
- The powder and chews drop curcumin and black pepper, and add UC-II collagen. The powder is mixed into food; the chews are given as treats.
- Inflamex isn't a glucosamine product. It's a liquid with curcumin, marshmallow and Boswellia, and its composition lists soya bean oil.
- Cats are no longer covered. The capsule was sold for dogs and cats; the current joint products are labelled for dogs.
- Allergens: there's no allergen statement on the powder or chews. The chews' glucosamine comes from crustaceans, the chondroitin is porcine and the collagen is from poultry, and they contain salmon oil and brewer's yeast.
Why Cortaflex customers switch to MedPaw
If your dog's capsules have gone and you're choosing again anyway, here's how MedPaw differs from the current Cortaflex range.
The current Cortaflex dog range vs MedPaw
| The issue | Cortaflex | MedPaw |
|---|---|---|
| Format | No capsules now; powder to mix into food, a liquid, or chews | Soft chicken and bacon chew, given from your hand like a treat |
| What's in it | No MSM or green-lipped mussel listed | All six key joint actives, with the main amounts per chew on the label: MSM 185mg, glucosamine 170mg, chondroitin 70mg, green-lipped mussel 70mg, Boswellia 30mg, plus hyaluronic acid |
| Getting your money back | 30 days, first purchase of the powder or Inflamex only; Senior chews not listed; post back unused product at your cost | 60 days from delivery, for any reason; email us and keep the tub |
| Cancelling a subscription | Offered on some products; no cancellation terms published | Pause, change or cancel any time from your account, or just email us |
To be fair to Cortaflex, its powder and Senior chews give more glucosamine and Boswellia per serving than a MedPaw chew, include UC-II collagen, and have no loading phase. MedPaw contains green-lipped mussel (a mollusc) and gluten from brewer's yeast, so like the Cortaflex chews it isn't suitable for a dog with a shellfish allergy.
Our recommendation: if your dog was on the Cortaflex capsules and you'd rather not switch to a powder or liquid, try MedPaw. Start the day after the last capsule, give double for the first three weeks, and allow six to eight weeks to judge it. If you're not happy, email us within 60 days and we'll refund you. Try MedPaw Hip & Joint Chews.
If nothing has worked so far
If your dog is still stiff or sore after a fair trial of any supplement, see your vet. They may suggest pain relief, weight loss or an omega-3 fish oil at a proper dose, which has the strongest evidence for dogs with arthritis. Read what you can safely give a dog for joint pain and the best fish oil for dogs' joints.

Have Cortaflex HA capsules for dogs been discontinued?
Yes. Equine America's product page says it has "taken the decision to discontinue our Canine & Feline Capsules" because of the growing popularity of other products in its pet joint range.
What replaced the Cortaflex capsules?
There's no direct capsule replacement. Equine America points owners to Canine Cortaflex Working Dog Jointcare powder or Canine Inflamex Solution. Its dog range also includes Cortaflex Senior Jointcare Dog Chews. Each has a different formula from the capsules.
Is the Cortaflex Working Dog powder the same as the capsules?
No. Per serving, the powder has more glucosamine, chondroitin, hyaluronic acid and Boswellia, adds UC-II collagen, and drops the curcumin and black pepper extract the capsules contained. It's mixed into food rather than given as a capsule.
Can I still buy Cortaflex capsules for my dog?
Not from Equine America, which has discontinued them, and they weren't in the dog range we saw on cortaflex.co.uk. Some other sellers may still have old stock.
What's the best alternative to Cortaflex capsules?
If you'd rather not move to a powder or liquid, we'd recommend MedPaw Hip & Joint Chews: a soft chew given like a treat, with all six key joint actives, the main amounts per chew on the label, and a 60-day money-back guarantee with nothing to send back.
Can I switch from Cortaflex to MedPaw straight away?
Yes. Start MedPaw the day after your dog's last Cortaflex dose. There's no need for a gap, and you shouldn't give both. Check with your vet first if your dog takes any medication.
