If your dog has started to slow down on walks or take a little longer to get up from their bed, it is natural to start looking at joint supplements. Flexadin and Dasuquin are two names that often come up side by side, and many owners want to know which one is "better".
The honest answer is that a blog post cannot crown a winner. The research behind this article does not list either product's ingredients, format, dose or guarantee, and we would rather say so than guess. What we can do is show you how to read two labels side by side, so you can make a calm, informed choice with your vet.
Think of this as a comparison guide rather than a verdict. By the end, you should know what to check, what to ask, and when a supplement is not the right first step.
Weighing up Flexadin: the six actives worth looking for
When owners compare Flexadin and Dasuquin, the most useful question is what each daily dose actually contains. A simple yardstick is six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. The table below uses it to score six products, including MedPaw, which is our own.
Flexadin and Dasuquin are not columns in this table, so we will not guess at their formulas. Use the table to see how the checklist works, then hold any label you are considering up against it.

MedPaw is the only product here with all six key actives. The nearest is NutraPaw with 4 of 6, then YuMOVE and Nutraquin+ with 3 each, and Seraquin and Synoquin EFA with 2. For a dog that is slower on walks or stiff getting up, one chew covering all six gives broad daily support for joints, mobility and comfort.
To judge Flexadin, check its pack or the manufacturer's page for each of the six actives and count them. MedPaw's 6 of 6 is the score to compare against. MedPaw also adds omega-3, vitamins C and E and zinc in a soft daily chew, with a 60-day money-back guarantee and Subscribe & Save.

Why there is no single "winner" for every dog
Every dog with joint problems is an individual. The cause of the discomfort, your dog's age, size, weight and lifestyle, and any other health conditions all shape what a sensible plan looks like. What suits one dog may not suit another.
That is why a generic "Product A beats Product B" claim deserves a little caution. A label can tell you what is in a product. It cannot tell you how your dog will get on, and it cannot replace an examination by your vet.
What we can and cannot say about Flexadin and Dasuquin
Flexadin and Dasuquin are both joint supplements that owners commonly compare. That is as far as we can responsibly go here.
The sources we used do not state the formula, format, feeding guide, guarantee or price of either product. We have not listed their ingredients, because we cannot verify them and formulas can change over time. If you see a detailed ingredient list for either product elsewhere, check it against the pack in your hand.
Please check the current label or the manufacturer's own website for the full ingredient list, the amount of each active, the format and the feeding guide. Then ask your vet which approach suits your dog.
A quick look at what is going on inside a stiff joint
A few basics make it easier to judge what a supplement can reasonably do. They also explain why your vet matters so much.
What arthritis actually is
Arthritis, also called degenerative joint disease, is the way a joint responds to damage. Several things can happen together:
- inflammation in and around the joint
- wearing down of the cartilage
- damage to the lining of the joint
- growth of scar tissue and bone tissue as the body tries to repair the damage
It has many possible causes
Joint instability, ligament and tendon damage and broken bones are all recognised causes. For some dogs, surgery may be one of the options a vet discusses. Only a vet can judge whether that applies to your dog.
It is a long-term condition
Arthritis is a long-term condition, but a great deal can be done to help keep a dog comfortable and to look after their mobility day to day. That is encouraging, and it is a good reason to talk to your vet rather than rely on guesswork.
How to compare two joint supplement labels like for like
Put the two labels next to each other, ideally on the table with a pen and paper. The aim is to compare what each product gives your dog in a day, not how the front of the pack looks.
What to check on any dog joint supplement label
| What to check | Why it matters | Where to look |
|---|---|---|
| Active ingredients and amount of each | Two products can name the same ingredient but provide different amounts per day | Composition and analytical constituents on the label |
| Format | Tablet, chew, capsule or powder, and whether your dog will take it daily | Front of pack and product page |
| Feeding guide by bodyweight | Sets how many servings your dog needs, which affects cost per day | Feeding instructions |
| Guarantee or returns policy | Tells you what happens if your dog will not take it or you are unsure | Manufacturer's website |
| Complementary feed labelling | Shows how the product is categorised for dogs in the UK | Label and manufacturer information |
| Ingredients your dog may react to | Avoids repeating a past sensitivity, such as shellfish or particular proteins | Full ingredient list |
For guidance only, not a diagnosis.
Work out the cost per day, not per pack
A pack that looks cheaper may hold fewer daily servings for a dog of your dog's weight. Check the feeding guide and work out how many servings your dog needs each day. Then divide the pack price by the number of days it will last. That gives you a much fairer comparison.
Think about the format
Supplements are made for regular use, so a routine your dog accepts really matters. A dog that fights tablets may do better with another format. A dog that takes a supplement happily every day gives you a far steadier routine than one you have to coax or disguise.
Check for sensitivities
Read the whole ingredient list, not just the headline actives. If your dog has reacted to shellfish, a particular protein or anything else in the past, ask your vet before starting. And if you are not sure whether an ingredient could be a problem, ask.
Introduce one change at a time
If you start a new supplement, change the diet and alter the walking routine all in the same fortnight, you will not know which change made a difference. Try to make one change at a time, and give it a fair run before changing anything else.
Keep a simple diary
Memory is not very reliable when changes are gradual. A few short notes each week are far more useful, for you and for your vet. Consider tracking:
- how easily your dog gets up after resting
- willingness to walk and to use stairs
- behaviour on the usual walk
- any stiffness after exercise
Dated notes or short phone videos of your dog getting up and walking help your vet judge change more reliably than recollection can.
Be patient but realistic
Supplements are meant for steady, regular use, not an overnight change. Follow the label's guidance on how long to give a product before judging it. Then share your diary with your vet at the next check-up, so you can decide together whether to carry on.
Tell your vet what your dog takes
Mention every supplement, treat and medicine at appointments. This matters most if your dog is on prescribed pain relief or other medication, because your vet needs the full picture to confirm that a supplement is suitable.
Support the basics alongside any supplement
A supplement is only one part of looking after a dog's mobility. Every dog's plan is individual, so these are sensible things to raise with your vet:
- body weight, and whether your dog is at a healthy size
- the type and amount of exercise, including whether short, regular walks suit better than occasional long ones
- comfortable, supportive bedding
- grip on slippery floors, such as rugs or mats on laminate and tiles
These are general points rather than claims about any product, and your vet can tailor them to your dog.
When to see your vet
A joint supplement should never delay a proper diagnosis. Your vet can assess your dog through examination and x-ray to help identify the cause and guide management.
How quickly to seek veterinary advice
Slowing down, not yet examined
Book an appointment before starting a supplement, especially if your dog has never been checked for joint problems.
Changes in mobility or signs of discomfort
Difficulty rising, climbing stairs or jumping into the car, reluctance to be touched or lifted, or licking at a joint all deserve a prompt appointment. So does no change, or a worsening, after starting a supplement.
Sudden or severe limp
If your dog will not put weight on a leg, cries out in pain, or has had an injury, seek same-day or emergency veterinary attention.
Also speak to your vet if your dog has other health conditions or takes regular medication, so they can confirm a supplement is suitable. If your dog seems unwell after starting a new product, with vomiting, diarrhoea, itching or loss of appetite, stop it and call your vet.
Injuries matter too. Damage to ligaments, tendons or bones is a recognised cause of later joint problems, so mention any past injury at your next visit.
Where MedPaw fits
This section is about MedPaw's own product only. It is not Flexadin or Dasuquin, it does not share a formula with either, and we are not saying it is better or worse than them. We simply hold no verified facts to compare them.
MedPaw Hip & Joint Chews Max is a daily soft chew and a complementary feed for dogs, made to support joints and mobility alongside veterinary care.
- Key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata.
- Also contains: omega-3 from green-lipped mussel and flax seed, vitamins C and E, and zinc. It is made with rapeseed oil and glycerine.
- Feeding: 1 chew a day up to 4kg, 2 for 5-17kg, and 2-3 for 18kg and over. The amount is doubled for the first three weeks, and 2-3 months of daily use is recommended.
- Guarantee and purchase: a 60-day money-back guarantee, with Subscribe & Save available.
As with any supplement, check the label against your dog's needs and ask your vet if you are unsure.
Bringing it all together
Choosing between Flexadin and Dasuquin is less about finding a champion and more about finding what suits your dog. Read each current label closely, compare the actives, the format, the feeding guide and the guarantee, and work out the cost per day for your dog's weight.
Make one change at a time, keep a short diary, and share it with your vet. If anything about your dog's mobility worries you, a vet visit comes first, and the supplement decision can follow from there.
Is Flexadin or Dasuquin better for dogs?
We cannot responsibly name a winner, because every dog is different and we do not hold verified facts on the formula, format, dose or guarantee of either product. The best approach is to read each current label, compare the actives, the format, the feeding guide and the cost per day for your dog's weight, then ask your vet which suits your dog.
What should I compare when choosing between two dog joint supplements?
Look at the active ingredients and the amount of each per daily serving, the format, the feeding guide for your dog's bodyweight, and the guarantee or returns policy. It also helps to check the full ingredient list for anything your dog has reacted to before, such as shellfish. Your vet can help you judge whether a product is suitable.
How do I work out the cost per day of a dog joint supplement?
Check the feeding guide for your dog's weight and work out how many servings they need each day. Then divide the pack price by the number of days the pack will last at that amount. This gives a much fairer comparison than the pack price alone, because a cheaper pack may hold fewer daily servings.
How long should I give a joint supplement before deciding if it suits my dog?
Supplements are designed for steady, regular use rather than an overnight change, so follow the guidance on the label. For MedPaw Hip & Joint Chews Max, the label recommends 2-3 months of daily use. Keeping a short diary of how your dog gets up, walks and manages stairs can help you and your vet review how things are going.
How many MedPaw chews would a 20kg dog have each day?
The label guides 2-3 chews a day for dogs of 18kg and over, doubled for the first three weeks. Your dog's exact amount within that range is worth confirming against the label on your tub. Please speak to your vet if you are unsure what is right for your dog.
Should I see my vet before starting a joint supplement?
Yes, particularly if your dog is slowing down, struggling to get up or has never been examined for joint problems. A supplement should never delay a proper diagnosis, and your vet can check whether it is suitable alongside any other health conditions or medication. A sudden or severe limp needs same-day veterinary attention.
