Quick answer: we've read the reviews, complaints and small print for 34 dog joint supplement brands sold in the UK. The same problems come up again and again: subscriptions that are hard to cancel, dogs refusing tablets, amounts per dose that aren't published, money-back guarantees with conditions attached, and owners who simply see no difference. Pick a brand below for the full picture. If you've hit any of those problems, we'd recommend trying MedPaw Hip & Joint Chews instead: a soft chew dogs take like a treat, the main amounts per chew on the label, a subscription you can pause or cancel any time, and a 60-day money-back guarantee with nothing to send back.

UK dog joint supplement brands: reviews and guides
The complaints that come up across brands
Subscriptions that are hard to stop
For several of the larger brands, the biggest source of one-star reviews isn't the supplement itself but the subscription: deliveries arriving more often than expected, cut-off dates before the next order, and orders that can't be cancelled once they've been charged. Our cancelling guides set out each brand's own terms, step by step.
Dogs that won't take tablets
A supplement only helps if it gets eaten every day. Many brands are tablets, capsules or powders, and a steady stream of owners report dogs picking them out of their food.
Labels that don't show the amounts
Several brands list their ingredients but not how much of each active is in a dose, which makes it hard to compare products or know what your dog is getting.
Guarantees with conditions
Some guarantees only apply to first orders, to orders from the brand's own website, or if you phone first and send back the packaging. A few brands have no money-back guarantee at all.
No difference
Every brand gets reviews from owners who saw no change. Sometimes that's a short trial or a missed loading phase; sometimes the dog needs a vet rather than a supplement. Our "not working" guides go through the usual reasons.
Why owners switch to MedPaw
The common complaints, and how MedPaw handles them
| The complaint | MedPaw |
|---|---|
| Hard to cancel | Pause, change or cancel any time from your account, or just email us |
| Dog won't take tablets | Soft chicken and bacon chew, given from your hand like a treat |
| Amounts not published | 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 |
| Guarantee conditions | 60 days from delivery, for any reason; email us and keep the tub |
| Long loading phase | Double for just the first three weeks |
Our recommendation: if your current supplement has let you down on any of these points, switch to MedPaw. Swap rather than stack: stop the old product and start MedPaw the next day. Give it six to eight weeks, and if you're not happy, email us within 60 days and we'll refund you. MedPaw contains green-lipped mussel and brewer's yeast, so it isn't suitable for dogs with a shellfish allergy. 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.

Which dog joint supplement brands have the most complaints?
The biggest brands get the most complaints simply because they sell the most. In the reviews we read, the most common problems across brands were subscriptions, dogs refusing tablets, a lack of results and guarantee conditions. Each brand page above shows that brand's own complaints.
Are dog joint supplement reviews reliable?
Partly. Many headline ratings cover a whole store, including delivery and other products, and some brands have very few or very old reviews. Look for reviews that describe the dog's mobility after several weeks, not just fast delivery.
What's the best alternative if my dog's supplement isn't working?
First check you've given it long enough at the right dose, and see your vet if your dog is limping or in pain. If you want to try something else, we'd recommend MedPaw Hip & Joint Chews: a soft chew with all six key joint actives and a 60-day money-back guarantee.
Can I switch joint supplements straight away?
Yes. Stop the old one and start the new one the next day. There's no need for a gap, and you shouldn't give both. Check with your vet first if your dog takes any medication.
How long should I give a joint supplement before judging it?
Six to eight weeks, and up to three months for older dogs. Keep a weekly note of how your dog gets up, walks and handles stairs so you can compare fairly.
