  • Natural substance supporting joint cartilage and fluid

Glucosamine is one of those natural compounds that the body needs to build & maintain cartilage, that is the stuff that surrounds your joints & lets them move smoothly. It also helps keep joint fluid in check, this stuff that stops your joints from grinding against each other.

Benefits of Glucosamine for Dogs

  • Reduces joint inflammation and pain
  • Improves joint lubrication and cartilage repair
  • Enhances mobility, especially in aging or large breeds


Glucosamine can make a really big difference for dogs, particularly those dealing with joint issues or arthritis. It works by helping to ease joint inflammation and pain, all by supporting the body’s own repair processes – it’s like nature’s own painkiller. With that pain under control, dogs can move around a whole lot more easily and with way less stiffness, which makes a huge difference to their overall quality of life. 

Glucosamine also plays a key role in getting the joint lubrication right, by helping to boost the production of that soggy synovial fluid that cushions and protects the joints when you move. Plus it’s got some other tricks up its sleeve too – it really helps with cartilage repair and maintenance, which can help to slow down those degenerative joint diseases like osteoarthritis from getting any worse. That’s especially good news for older dogs and the big breeds – they’re the ones that get joint wear and tear just through growing up. 

Now – it’s true that the research on glucosamine isn’t rock solid yet, but loads of vets swear by it as a safe and useful bit of kit for dog owners to add to their toolkit when it comes to looking after joint health. Used properly, and with the vet’s guidance, it can really make a big difference to your dog’s ability to get around and have a good time – and that’s got to be worth it in the end.

Dosage Guidelines

  • Based on dog’s weight (small, medium, large, giant categories)
  • Typically 250 mg to 1,500 mg daily depending on size
  • Consult a vet for precise dosing


Working out the right glucosamine dose for your dog is really all about getting it right for their weight.

This is what we know as a general guideline – the right amount is tied to how much your dog weighs & these are the weights most vets use to figure out the right dose:

  • Small dogs : under 25 lbs – You’re looking at a daily dose of anywhere from 250 to 500 mg
  • Medium dogs : 500 mg per day
  • Large dogs :  about 1000mg per day
  • Big dogs : You can give up to 1,500 mg per day

Some vets suggest you start with a ‘loading dose’ – this can be roughly two times what they’d recommend as a maintenance dose – for the first 4 to 6 weeks to get that extra joint support in, before then switching to the maintenance level. Every single dog is a bit different though, depending on age, joint condition & overall health. Always get advice from your vet before you start giving any supplements to make sure you get the right dose for your dog. Giving the right dose could be the difference between getting the benefits – think reducing inflammation, getting joint lubrication going again, helping repair cartilage and so on – and getting unwanted side effects.

Safety and Side Effects

  • Generally safe with rare side effects like upset stomach or increased thirst
  • Avoid if dog has shellfish allergy (supplements usually derived from shellfish)

In​‍​‌‍​‍‌​‍​‌‍​‍‌ general, glucosamine poses little risk to the health of dogs and rather infrequently has mild side effects. Sensitivities of dogs’ stomachs, vomiting, diarrhea or cooling may increase as well as urination if a dog is given a supplement in the wrong dosage or is just starting with the supplement. 

Usually, these symptoms go away on their own during the period of adaptation to the supplement. Nevertheless, glucosamine supplements can be very harmful to dogs since they are mostly made from shellfish, thus canine shellfish allergic should not take such supplements and if necessary, should take alternative supplements so as not to develop an allergic reaction such as skin getting irritated, itching or getting more severe symptoms.

It is really important to watch your dog carefully when giving him glucosamine for the first time, particularly just after the first dose, to be able to detect and locate any adverse reactions at an early stage.

You should always talk to your vet before giving your dog glucosamine to make sure it is safe for your dog and also follow the instructions on the dosage very carefully. Such a stance not only minimizes possible dangers but also maximizes the positive effects on the joints, thus making glucosamine a handy, tolerable option for pretty much any dog suffering from arthritis or joint ​‍​‌‍​‍‌​‍​‌‍​‍‌pain.
