How much glucosamine for a dog? Daily amounts by weight
There is no single official glucosamine dose for dogs. The one commonly cited maintenance figure, from a 2017 dvm360 article, is about 15 mg per kg a day: roughly 410 mg for a 60 lb dog. Product labels vary and often give more. Follow your product's label and check with your vet.
| Official canine dose | None established |
|---|---|
| Commonly cited maintenance figure | About 15 mg/kg/day (one source) |
| Conversion | 1 kg = 2.2046 lb |
| 60 lb dog at 15 mg/kg | About 410 mg/day |
| MSM dose for dogs | No established canine dose |
Is there an official glucosamine dose for dogs?
No. There is no universal or official glucosamine dose for dogs. Cornell's canine health center says there is "no universal recommendation" for how much of these ingredients a dog needs (Cornell). The AKC and PetMD both leave the amount to your vet and the product label (AKC; PetMD).
What you will find instead:
- One commonly cited maintenance figure. A 2017 dvm360 article gives 500 to 1,000 mg a day for a 75 lb dog, "which works out to about 15 mg/kg" (dvm360). That is the low end of the range: 1,000 mg for a 75 lb dog is about 29 mg/kg. This is a single source, not a consensus.
- Trial doses that are hard to pin down. A 2017 review found canine glucosamine studies used different manufacturers, salt forms, doses and durations (Bhathal et al.; Vet Times). The abstract of the best-known trial, Moreau et al. 2003 (71 dogs with osteoarthritis), does not report the dose of the glucosamine product it tested (Moreau et al.).
- Label doses that vary. Each brand sets its own amount per chew and chews per day.
Keep in mind that the research behind glucosamine is mixed. Our guide to the evidence on dog joint supplements covers what the trials found.
How do you work out glucosamine mg per kg for your dog?
Use this formula:
- Your dog's weight in kg = weight in lb ÷ 2.2046
- mg per kg = total daily mg of glucosamine ÷ weight in kg
Per pound, 15 mg/kg is about 6.8 mg per lb.
Glucosamine dosage for dogs by weight chart
This chart shows the 15 mg/kg figure and what common daily totals work out to at each weight. It is arithmetic, not a recommendation.
| Dog weight | Weight in kg | At 15 mg/kg (cited figure) | 500 mg/day = | 1,000 mg/day = | 1,500 mg/day = | 2,000 mg/day = |
|---|---|---|---|---|---|---|
| 10 lb | 4.5 kg | about 70 mg | 110 mg/kg | 220 mg/kg | 331 mg/kg | 441 mg/kg |
| 30 lb | 13.6 kg | about 205 mg | 37 mg/kg | 73 mg/kg | 110 mg/kg | 147 mg/kg |
| 50 lb | 22.7 kg | about 340 mg | 22 mg/kg | 44 mg/kg | 66 mg/kg | 88 mg/kg |
| 60 lb | 27.2 kg | about 410 mg | 18 mg/kg | 37 mg/kg | 55 mg/kg | 73 mg/kg |
| 75 lb | 34.0 kg | about 510 mg | 15 mg/kg | 29 mg/kg | 44 mg/kg | 59 mg/kg |
| 100 lb | 45.4 kg | about 680 mg | 11 mg/kg | 22 mg/kg | 33 mg/kg | 44 mg/kg |
Calculated at 1 kg = 2.2046 lb, rounded. The 15 mg/kg figure is from a single 2017 dvm360 article.
Many joint chews, including ours, give more than 15 mg/kg at their label dose.
No trial we found shows that a higher daily amount works better.
How much glucosamine for a 10 lb dog?
A 10 lb dog weighs about 4.5 kg. At the commonly cited 15 mg/kg, that is about 70 mg a day. Small dogs can get far more than this from a single chew, because many chews are not made in small strengths.
One 500 mg chew is about 110 mg/kg for a 10 lb dog. That is well above the cited figure.
How much glucosamine for a 30 lb dog?
A 30 lb dog weighs about 13.6 kg. At 15 mg/kg, that is about 205 mg a day. A label that gives 1,000 mg a day works out to about 73 mg/kg.
How much glucosamine for a 50 lb dog?
A 50 lb dog weighs about 22.7 kg. At 15 mg/kg, that is about 340 mg a day. At 1,500 mg a day, the amount works out to about 66 mg/kg.
How much glucosamine for a 60 lb dog?
A 60 lb dog weighs about 27.2 kg. At 15 mg/kg, that is about 410 mg a day. That is below the 500 to 1,000 mg range dvm360 quotes for a 75 lb dog, as you would expect for a smaller dog. A label that gives 1,500 mg a day works out to about 55 mg/kg for a 60 lb dog.
How much glucosamine for a 75 lb dog?
A 75 lb dog weighs about 34 kg. At 15 mg/kg, that is about 510 mg a day, which matches the low end of the 500 to 1,000 mg range in the dvm360 article.
How much glucosamine for a 100 lb dog?
A 100 lb dog weighs about 45.4 kg. At 15 mg/kg, that is about 680 mg a day. Many labels give large dogs 3 or 4 chews a day, so check how long a container lasts.
What does GoodYears Mobility give at its label dose?
The table below shows our chew's label amounts. This is our product's label dose, not a universal recommendation. Each chew contains 500 mg glucosamine HCl, 400 mg MSM, 150 mg green-lipped mussel and 110 mg chondroitin sulfate.
| Dog weight | Chews a day | Glucosamine HCl | MSM | Green-lipped mussel | Chondroitin | One jar lasts |
|---|---|---|---|---|---|---|
| Up to 15 lbs | 1 | 500 mg | 400 mg | 150 mg | 110 mg | 60 days |
| 15 to 45 lbs | 2 | 1,000 mg | 800 mg | 300 mg | 220 mg | 30 days |
| 45 to 75 lbs | 3 | 1,500 mg | 1,200 mg | 450 mg | 330 mg | 20 days |
| Over 75 lbs | 4 | 2,000 mg | 1,600 mg | 600 mg | 440 mg | 15 days |
Daily amounts at the label dose of GoodYears Mobility (per chew: glucosamine HCl 500 mg, MSM 400 mg, green-lipped mussel 150 mg, chondroitin sulfate 110 mg). Contains shellfish. Check with your vet first if your dog takes any medication.
At our label dose, glucosamine works out to about 110 mg/kg for a 10 lb dog, 73 mg/kg at 30 lb, 66 mg/kg at 50 lb, 55 mg/kg at 60 lb, and 44 mg/kg at 75 and 100 lb. Glucosamine is the dose-led ingredient in our chew. Our green-lipped mussel and chondroitin are lower relative to the figures sources cite, and our why our amounts guide explains that openly. You can see the full label on the GoodYears Mobility page or check the daily amounts FAQ.
Does your dog need a loading dose?
Loading phases are mostly a brand practice with limited evidence behind them.
- The 2017 dvm360 article describes a loading amount of "two times maintenance for four to six weeks" (dvm360).
- Some brands build one into their labels. A Chewy Q&A answer for Cosequin soft chews gives dogs over 60 lb 3 chews a day for the first 4 to 6 weeks, then 1 to 2 (Chewy). A Wuffes blog post describes a four-week double-dose loading period (Wuffes).
- We did not find a canine trial that compared a glucosamine loading phase with no loading phase.
Glucosamine HCl vs sulfate: does the form change the dose?
Glucosamine comes as hydrochloride (HCl), sulfate or N-acetylglucosamine. The AKC cites a 2012 review of human studies in which the HCl form "had little effect" while the sulfate form performed better (AKC). That is human data and, in our research, a single source on this question.
We found no canine trial comparing the forms. GoodYears Mobility uses glucosamine HCl.
What about MSM and chondroitin dosing?
MSM. There is no established canine MSM dose. A dvm360 article says there is no published research on MSM in dogs, and a 2022 meta-analysis found MSM only inside multi-ingredient products (dvm360; Barbeau-Grégoire et al.). Any per-pound MSM figure you see is a label choice, not a research-based dose.
Chondroitin. The same dvm360 article says chondroitin's standalone dose is the same as glucosamine's, which would be about 15 mg/kg. That is again a single source. At our label dose, our 110 mg per chew gives about 15 mg/kg or more for most dogs up to about 30 lb, and roughly 10 to 16 mg/kg for most larger dogs, lower for very large dogs.
Green-lipped mussel, briefly: there are "no defined doses" (PetMD). A 2009 trial used 20 to 49 mg/kg a day for 10 days, then half (Hielm-Björkman et al.), and 77 mg/kg a day is a commonly cited figure from Cornell and dvm360. Our chew is below those amounts. Our glucosamine vs green-lipped mussel guide goes deeper.
Is glucosamine safe for every dog?
Glucosamine is generally well tolerated. VCA Animal Hospitals lists mild stomach upset, such as gas or soft stools, as the usual side effect, and says to stop and call your vet if you see signs of an allergic reaction (VCA). Check these first:
- Shellfish allergy. Many glucosamine products, including ours, come from shellfish. PetMD advises avoiding glucosamine in dogs with a known shellfish allergy (PetMD). Our chew also contains green-lipped mussel.
- Diabetic dogs. Sources conflict. dvm360 quotes a vet saying glucosamine can be given safely to diabetic dogs, while VCA lists insulin and other diabetes drugs as interactions to use with caution. Talk to your vet.
- Medications. VCA lists possible interactions with some NSAIDs (including carprofen), blood thinners such as warfarin and heparin, doxorubicin and sertraline.
- Pregnancy and breeding. Check with your vet first.
What to do next
- Weigh your dog and work out kg using the formula above.
- Follow your product's label, and ask your vet about the right amount if your dog has a health condition or takes medication.
- Give it time. Read how long joint supplements take to work, and track getting up, stairs and walk length for 60 to 90 days.
- Compare labels with our joint chew label checklist.
Questions owners ask
How much glucosamine should I give my dog per pound?
There is no official per-pound dose. The commonly cited maintenance figure of about 15 mg per kg works out to roughly 7 mg per pound of body weight a day, but that figure comes from a single 2017 dvm360 article. Many product labels give more than this. Follow your product's label, which is written for that product's strength, and ask your vet if your dog has a health condition or takes medication.
Can I give my dog human glucosamine?
Talk to your vet first. PetMD advises never giving a dog a supplement labeled for human use without veterinary guidance, because some human products contain ingredients that are dangerous for dogs. Human products are also dosed for people, so the amount per tablet may not suit your dog's weight. A product made for dogs with clear mg per chew is easier to dose correctly.
Do dogs need a loading dose of glucosamine?
Not necessarily. A 2017 dvm360 article describes a loading amount of twice maintenance for four to six weeks, and some brands use a higher starting amount on their labels. We did not find a trial that compared starting with a loading phase against not using one. GoodYears Mobility uses the same daily amount from day one. If your product's label includes a loading phase, follow the label.
Can a dog have too much glucosamine?
Glucosamine is generally well tolerated in canine trials, and mild stomach upset such as gas or soft stools is the main side effect listed by VCA Animal Hospitals. Do not give two doses at once to catch up after a missed one. If your dog eats a whole container, call your vet or a pet poison hotline, since the other ingredients and flavorings in the chew matter too.
Is glucosamine safe for diabetic dogs?
Sources disagree, so ask your vet. A 2017 dvm360 article quotes a vet saying glucosamine can be given safely to diabetic dogs. VCA Animal Hospitals lists insulin and other diabetes drugs among the medicines to use with caution alongside glucosamine and chondroitin. Your vet knows your dog's glucose control and can tell you whether to start, and whether to monitor more closely at first.
What is the MSM dosage for dogs per pound?
There is no established canine MSM dose, because there is no published canine efficacy research on MSM alone. A 2022 meta-analysis found MSM only inside multi-ingredient products. Labels set their own amounts. For reference, one GoodYears Mobility chew has 400 mg of MSM, which at our label dose works out to about 20 mg per pound for a 60 lb dog. That is our label amount, not a recommendation.
