If you are searching for an alternative to a Johnson's 4Joints product, the chances are your dog has started to slow down. Perhaps they are stiff after a nap, hesitate at the bottom of the stairs, or cut a walk short when they used to lead the way. Wanting to help is completely natural.
Maybe you have tried a supplement already and are not sure it suits your dog. Or you would like a clearer feeding guide, a different format, or a longer ingredient list. Whatever the reason, the most useful skill is knowing how to compare any two joint supplements fairly, rather than simply swapping one brand name for another.
This guide covers what to look for on a label, how some well-known products differ, how to switch safely, and when to call your vet. A supplement is a complementary feed that sits alongside veterinary care. It never replaces it.
Switching joint supplement? Start with the list of actives
If you are weighing up a change from Johnson's 4Joints, the most useful first step is to compare declared actives on the label rather than the claims on the front of the pack. The table below does that for MedPaw, our own product, and five other well-known UK joint supplements.
It opens with a score out of six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata.

MedPaw is the only product of the six to list all six key joint actives, scoring 6 of 6. NutraPaw scores 4, YuMOVE and Nutraquin+ score 3 each, and Seraquin and Synoquin EFA score 2 each. For a dog who is slowing down, that breadth puts more of the ingredients owners look for into one daily routine, to support joints, mobility and comfort.
MedPaw is also a soft chew, which makes a daily habit simple to keep, and feeding is by weight: the amount is doubled for the first three weeks, with 2-3 months of daily use recommended for optimal results.
If you decide to try it, there is a 60-day money-back guarantee, and Subscribe & Save is available. Use it alongside your vet's advice.

Why owners start looking for an alternative
Most owners who look for a different joint supplement fall into one of a few groups. Knowing which group you are in makes the comparison much easier.
- Your dog is slowing down and you want to start a daily routine for the first time.
- You have used a supplement but are unsure it is the right match for your dog.
- You want more detail on ingredients, or a feeding guide that is easy to follow by weight.
- Your dog is fussy about the format and spits out tablets, capsules or granules.
Keep one thing in mind. Within a single brand, different products can have quite different formulations. If you have been using a particular product, check the label of that exact one rather than assuming it matches another product with a similar name. That way you are comparing like with like.
What to look for on a joint supplement label
The front of the pack tells you very little. The useful information is on the back, in the ingredient and analysis panel and the feeding guide. Here is a simple checklist you can use on any product.
A simple label checklist for any dog joint supplement
| Question to ask | Why it matters | What to look for |
|---|---|---|
| Which joint-support ingredients are listed? | Products vary a great deal in what they contain. | The ingredient named clearly on the label, not just implied by the marketing. |
| What format is it? | A supplement can only support your dog if they eat it every day. | A soft chew, tablet, capsule or powder your dog will actually accept. |
| Is there a feeding guide for my dog's weight? | Under or over-feeding makes consistency harder. | Clear weight bands and any loading period explained. |
| What is the guarantee? | It lets you try the product with less risk. | The length of the guarantee and how a refund works. |
For guidance only, not a diagnosis.
Ingredients
Some supplements contain just a few ingredients, while others combine several. More is not automatically better for every dog, but you deserve to know exactly what you are choosing between. If you want a particular ingredient, such as MSM, Boswellia or hyaluronic acid, look for it by name.
Also look at how an ingredient is listed. Chondroitin, for example, can appear as its own ingredient in one product and only as part of green-lipped mussel in another. The label will tell you which.
Format
Soft chews, tablets, chewable tablets and capsules all exist, and none is right for every dog. A dog who spits out tablets may do better with a soft chew. A dog who happily swallows a tablet hidden in food may not mind either way. The best format is the one your dog takes without a fuss, every single day.
Feeding guide and guarantee
A clear feeding guide for your dog's weight takes the guesswork out of daily use. Check whether there is a loading period at the start, as some products ask you to give a higher amount for the first few weeks.
Guarantees vary too, from several weeks to a few months, and some products do not state one at all. A guarantee will not tell you whether a product suits your dog, but it does lower the risk of trying it.
How some well-known options differ
The details below come from each manufacturer's published information as of September 2026. Each of these products suits some dogs and owners. The aim here is simply to show how much labels can vary.
- NutraPaw Joint Support is a tablet. It lists glucosamine, MSM, green-lipped mussel, hyaluronic acid, turmeric and collagen, with omega-3 from the mussel and manganese. It does not list chondroitin or Boswellia. It has a 90-day guarantee.
- YuMOVE Joint Support PLUS Max is a tablet. It lists glucosamine, green-lipped mussel, hyaluronic acid and fish oil, with chondroitin only via the mussel, plus vitamins C and E and manganese. It does not list MSM, Boswellia, turmeric or collagen. It has a 6-week guarantee.
- Seraquin Joint is a chewable tablet. It lists glucosamine, chondroitin and turmeric. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, omega-3 or collagen. A guarantee is not stated.
- Synoquin EFA comes as a tablet or capsule. It lists glucosamine, chondroitin and krill oil, plus vitamin C and zinc. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, turmeric or collagen. A guarantee is not stated.
- Nutraquin+ is a capsule. It lists glucosamine, chondroitin and Boswellia, plus vitamin C and zinc. It does not list MSM, green-lipped mussel, hyaluronic acid, omega-3, turmeric or collagen. A guarantee is not stated.
Looking across these, formats range from tablets and capsules to chewable tablets. Only some products list MSM, Boswellia, hyaluronic acid or green-lipped mussel. Guarantees run from 6 weeks to 90 days, with several not stated at all. None of this makes one product poor. It simply shows why reading the label matters.
Where MedPaw Hip & Joint Chews Max fits
MedPaw Hip & Joint Chews Max is a daily soft chew and a complementary feed for dogs. It combines six key joint-support ingredients: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. These are there to support healthy joints and mobility as part of your dog's wider care.
It also contains omega-3 from green-lipped mussel and flax seed, vitamins C and E, and zinc. The chews are made with rapeseed oil and glycerine.
Feeding guide
The feeding guide is by weight, with three bands:
- 1 chew a day for dogs up to 4kg
- 2 chews a day for dogs of 5-17kg
- 2-3 chews a day for dogs of 18kg and over
The amount is doubled for the first three weeks, then continued at the daily level. We recommend 2-3 months of daily use before you judge how things are going. If your dog falls between 4kg and 5kg, follow the pack guidance or contact the MedPaw team rather than guessing.
Guarantee and ordering
There is a 60-day money-back guarantee, and Subscribe & Save is available if you would like regular deliveries. To be fair, NutraPaw's published guarantee is longer than ours at 90 days, and YuMOVE's is shorter at 6 weeks. Which matters more depends on how you like to trial a product.
How to switch supplements safely
If you decide to change, the principle is to swap, not stack. Giving two joint supplements at once makes it hard to know what is working for your dog, and it can mean doubling up on similar ingredients.
- Stop the old supplement and start the new one on the same day, or the next.
- Follow the new product's feeding guide from day one, including any loading period.
- Keep it consistent. Joint supplements are meant for daily use over weeks, not days.
- Give it a fair trial. With MedPaw, that means 2-3 months before judging.
- Keep notes or short phone videos of how your dog gets up, climbs stairs and walks, so you can compare over time.
It also helps to write down your dog's current signs before you begin. Stiffness after rest, hesitation on stairs and shorter walks are all useful things to track. Memory is unreliable when changes are gradual.
If your dog takes any medication or has an existing health condition, please ask your vet before changing anything.
Everyday joint care matters as much as the supplement
A chew or tablet is only one part of the picture. These everyday habits play just as big a part in keeping a stiff or senior dog comfortable, and our complete guide to dog joint health goes into more detail.
- Healthy weight. Extra weight puts more load on joints. Ask your vet to check your dog's body condition and suggest a feeding plan if needed.
- Regular, gentle exercise. Short, steady walks usually suit a stiff dog better than occasional long ones. Avoid repeated ball-chasing and sudden twisting or jumping.
- Non-slip surfaces. Rugs or runners on laminate and tiles give weak or sore back legs something to grip.
- Comfortable bedding. A supportive, warm bed away from draughts helps older dogs rest well.
- Ramps and steps. These let your dog get into the car or onto the sofa without jumping.
- Nail care. Overgrown nails can change how a dog stands and walks.
- Warm-up and cool-down. A few minutes of slow walking before and after exercise suits stiff dogs.
One important safety point: never give human painkillers such as ibuprofen or paracetamol to a dog unless your vet has specifically told you to. Some are dangerous to dogs.
When to see your vet
A supplement should never delay a vet visit. Persistent stiffness or soreness deserves a proper examination, and your vet is the right person to decide whether a joint supplement is suitable alongside any other care, particularly if your dog is on medication.
How quickly should you act? A rough guide
Mild, early slowing down
Some stiffness after rest that eases with gentle movement. Mention it at your next vet check, and keep notes on how your dog moves.
Book a prompt appointment
Limping lasting more than a day or two or keeps returning, stiffness getting worse, reluctance on stairs or to jump into the car, licking at a joint, a swollen or warm joint, muscle loss in the back legs, behaviour changes, or little improvement after a fair supplement trial.
Seek urgent veterinary care
Sudden, severe lameness or refusing to put weight on a leg, collapse or being unable to stand, crying out, trembling or panting at rest, or lameness after an accident or injury.
Yelping, flinching or snapping when touched or lifted also deserves a prompt call. Your vet may recommend an examination, tests, pain relief, weight management or other options, and a supplement can sit alongside that plan if they agree it suits your dog.
Choosing a joint supplement does not need to be complicated. Read the full label, pick a format your dog will take every day, check the feeding guide and guarantee, and give it a consistent trial. Pair it with a healthy weight, gentle exercise and a comfortable home, and keep your vet closely involved.
What is a good alternative to Johnson's 4Joints for dogs in the UK?
There is no single best option, because it depends on your dog's format preference, the ingredients you want to see on the label and how you like to trial a product. Brands such as NutraPaw, YuMOVE, Seraquin, Synoquin and Nutraquin+ all differ in what they list, so compare the back of the pack rather than the front. MedPaw Hip & Joint Chews Max is a soft chew that lists glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata in one product.
How do I switch my dog from one joint supplement to another?
Swap rather than stack, so stop the old supplement and start the new one on the same day or the next. Follow the new product's feeding guide from day one, including any loading period, and keep it consistent so you can judge it fairly. If your dog takes medication or has a health condition, ask your vet before changing anything.
How many MedPaw chews does a 20kg dog need each day?
On the printed label, dogs of 18kg and over have 2-3 chews a day, and the amount is doubled for the first three weeks. MedPaw recommends 2-3 months of daily use before you judge how things are going. Each tub holds 60 chews, so check the label bands and count how long a tub will last at the amount you are feeding.
Does it matter whether a joint supplement is a chew, tablet or capsule?
It matters mainly because a supplement can only support your dog if they actually eat it every day. Some dogs spit out tablets or capsules, whilst others take them hidden in food without any fuss. MedPaw is a soft chew, and the best format is simply whichever one your dog accepts consistently.
Can I give my dog two joint supplements at once?
It is best not to, as giving two at once makes it hard to tell what is working and can mean doubling up on similar ingredients. Choose one product, follow its feeding guide and give it a fair, consistent trial. If you are unsure, your vet can advise on what suits your dog, especially if they are on any medication.
When should I see a vet rather than just try a supplement?
A supplement is a complementary feed and should never delay a vet visit. If your dog has limping that lasts more than a day or two, worsening stiffness, a swollen or warm joint, or is reluctant to use stairs, book an appointment. Sudden severe lameness, collapse or crying out needs urgent veterinary care.
